VIVOSTAT® AUTOLOGOUS FIBRIN SEALANT

For many years specialists have prepared autologous fibrin sealant based on thrombin and fibrinogen. The process is complicated, labour intensive and time consuming. With the Vivostat® system this process becomes fast and uncomplicated.

WHAT IS VIVOSTAT FIBRIN SEALANT

____________________________________________

The fully automated Vivostat® system prepares 5-6 ml of autologous fibrin sealant from 120 ml of the patient’s own blood in approx. 24 minutes.

Compared to conventional sealant products, Vivostat® Fibrin Sealant offers a multitude of benefits to both the patient and the surgeon:

  • Excellent safety profile and high biocompatibility

Vivostat® Fibrin Sealant is derived from the patient’s own blood and as such it demonstrates excellent biocompatibility. Unlike conventional products, which are most often based on single donor blood, pooled blood or bovine components (e.g. aprotinin), Vivostat® Fibrin Sealant does not contain any exogenous thrombin or bovine components. The autologous nature of Vivostat® efficiently eliminates the risks of bovine or human borne contaminants. This is the only way to protect the patient against viral diseases not yet identified.

  • Unique and versatile application devices

The wide selection of application devices provide the surgeon with unparalleled freedom in the use of fibrin sealant throughout surgery. The application devices can be used intermittently during the entire surgical procedure without experiencing the blockage that is common in conventional systems. Furthermore, Vivostat® Fibrin Sealant can be applied at very close range allowing for pinpoint application, and rapid polymerisation ensures that the fibrin remains where it is applied.

  • Superior physical properties

Clinical studies and comparative tests have demonstrated that Vivostat® Fibrin Sealant is superior to conventional fibrin sealants on important parameters such as time to haemostasis, elasticity, adhesion to tissue and impact on tissue.

VIVOSTAT® FIBRIN SEALANT OUTPERFORMS CONVENTIONALS PRODUCTS

____________________________________________________________________
The Vivostat® system offers a multitude of benefits to both the patient and the surgeon.

↓

  • As the fibrin sealant is autologous it shows excellent biocompatibility and efficiently eliminates the riscs of viral infection from products based on single donor blood, pooled blood or bovine components. This is the only way to guarantee the patient against viral diseases not yet identified.
  • In order to evaluate the clinically important physical properties of the fibrin sealant, a series of in-vitro rheological and tensile tests and ex-vivo tissue adhesion models were developed.
  • To read about the excellent physical properties of Vivostat® Fibrin Sealant, please select the area of interest in the menu to the left.

UNIQUE TECHNOLOGY ENSURES RAPID POLYMERISATION

An efficient sealant needs to polymerise quickly to build up its internal strength to provide a rapidly effective barrier.

Unlike other sealants, the polymerisation of Vivostat® Fibrin Sealant is activated by a simple pH change, and does not require an enzymic reaction. Polymerisation rates are therefore much faster than conventional fibrinogen/thrombin systems. Activation of the coagulation cascade initiates crosslinking of the fibrin polymer and Vivostat® Fibrin Sealant obtains 80% of its full strength within only 1 minute. The graph shows the polymerisation rate for Vivostat® Fibrin Sealant compared with two conventional sealants. Vivostat Polymerization Comparative kinetics of polymerisation of three fibrin sealants and influence on timing of tissue adhesion · Kjaergard H K et al. · Thrombosis Research 2000; 98: 221-228

VIVOSTAT® MOVES WITH THE TISSUE

Surgical sealants must be very flexible to move with the tissue.

This is especially important with e.g. lungs as the sealant might be applied when the lung is deflated. Unfortunately most compounds have an inverse relationship between strength and elasticity. Comparative tests have shown Vivostat® Fibrin Sealant to be extremely flexible, almost four times as flexible as competing products, without compromising strength. A high level of elasticity is particularly important for surgical procedures involving tissue that undergoes continual expansion or contraction such as the heart and lungs. The graph below shows the elongation at break (mm) for Vivostat® compared with two conventional fibrin sealants after 20 seconds. Comparative kinetics of polymerisation of three fibrin sealants and influence on timing of tissue adhesion · Kjaergard H K et al. · Thrombosis Research 2000; 98: 221-228

STRONG ADHESION TO TISSUES IS CLINICALLY RELEVANT

Many products focus on the tensile strength of the sealant, but neglect the most important parameter of adhesion to tissue.

Providing the internal strength of the sealant and the tissue itself are sufficiently high, it is the sealant:tissue adhesive strength that is the determining factor for tissue:tissue joint failure. A new test method was developed to measure adhesion properties. The test clearly demonstrated the superior performance of Vivostat® Fibrin Sealant compared to conventional products. The graph shows adhesion strength at first break after 20 seconds. Vivostat Tissue Adhesion Comparative kinetics of polymerisation of three fibrin sealants and influence on timing of tissue adhesion · Kjaergard H K et al. · Thrombosis Research 2000; 98: 221-228

VIVOSTAT® – ALWAYS THE SAME HIGH QUALITY

Unlike other patient-derived fibrin sealants, the fibrin concentration in the Vivostat® end-product is independent on the source or the plasma fibrinogen level.
Vivostat Processor 800 The Vivostat® Processor Unit is designed with specially developed sensors and software that carefully detect the individual patient fibrinogen level and automatically adjust the amount of diluting buffer to extract a fibrin sealant with a constant concentration of fibrinogen. In contrast the variation in fibrinogen concentration of conventional patient-derived sealants reflects the normal variation in the plasma fibrinogen level. The constant fibrinogen concentration in Vivostat® Fibrin Sealant guarantees the same excellent physical properties from patient to patient.

PLATELET RICH FIBRIN®
Platelets and growth factors have been used for many years to help regenerate tissue and stimulate bone formation in e.g. orthopaedic surgery.
Vivostat PRF Set

The thrombocyte solution used in these cases has traditionally been supplied by the blood bank.

Recently, a number of commercial products have entered the market with simpler and smaller devices that are still based on the same centrifugation technology. Most products still require sterile handling and have shortcomings in both the biophysical properties and the delivery system.

Vivostat has solved these problems by leveraging the revolutionary technology used in the Vivostat® system for the preparation and application of autologous fibrin sealant. By combining a fibrin sealant solution with a platelet concentrate, it is possible
to have a carrier, a controlled release and a medium for vascular ingrowth
– all in one product, Vivostat PRF® (Platelet Rich Fibrin).

A REVOLUTION IN TISSUE REGENERATION

  • Growth factors and fibrin are essential components when it comes to regeneration of tissue.

Using the Vivostat® system, you can prepare autologous platelets with multiple growth factors embedded in a fibrin sealant matrix. From 120 ml blood, 5-6 ml of Platelet Rich Fibrin (PRF®) is prepared. By combining a platelet concentrate with a fibrin sealant solution, it is possible to have a carrier, a controlled release and a medium for vascular ingrowth – all in one product, Vivostat PRF®. Compared to conventional PRP products, Vivostat PRF® has a number of advantages.

  • Combining the benefits of platelets and fibrin

With an average 7-fold increase over baseline blood levels, the platelet concentration in Vivostat PRF® exceeds the baseline platelet count of 1 million/μL, which has become a benchmark within platelet therapy. The fibrin matrix ensures a slow release of growth factors over time and effectively protects the growth factors against proteolytic degradation.

  • Superior application performance

The specially designed Vivostat® Spraypen® and the unique combination of platelets and fibrin ensures easy, accurate and efficient application of Vivostat PRF®. Due to instant polymerisation and excellent adhesive properties of the fibrin component, the PRF® solution remains where it is applied – even when applied on vertical or inverted surfaces. As the fibrin component in Vivostat PRF® is based on a fibrin 1 solution, there is no need to use a separate thrombin component.

THE IDEAL COMBINATION OF FIBRIN AND PLATELETS

 

Clinical studies have demonstrated the beneficial effect of combining a platelet concentrate with a high concentration of fibrin.

The Vivostat® system is the first and only system on the market to offer a convenient and fully automated process for the preparation of a platelet rich fibrin (PRF®).

Vivostat PRF® contains a variety of potent growth factors that stimulate fibroblast proliferation and tissue synthesis, e.g. TGF-β1,PDGF, VEGF, FGF-2 etc. Several in-vitro investigations confirm the unique characteristics of Vivostat PRF® and its ability to stimulate cell growth.

The unique combination provides the user with a number of benefits:

Benefits of Vivostat PRF

STIMULATION OF FIBROBLAST PROLIFERATION

 
Fibroblasts are fundamentally important in the process of tissue repair.

Apart from producing structural proteins such as collagen, they stimulate both angiogenesis and epithelialisation.

In-vitro studies have proven the positive effect of Vivostat PRF® on fibroblast proliferation. As illustrated, Vivostat PRF® increases the growth of normal human skin fibroblasts compared to control and performs significantly better than PDGF-BB (commercial growth factor).

Data for Fibroblast Cell Count

Bioactivity and stability of endogenous fibrogenic factors in platelet-rich fibrin, Lundquist R. et al., Wound Repair and Regeneration 2008; 16(3): 356-63

 

STIMULATION OF FIBROBLAST COLLAGEN SYNTHESIS

 

Collagen deposition is an essential component in the wound healing cascade.

In-vitro studies have illustrated the positive effect of Vivostat PRF® on the ability of fibroblasts to synthesise collagen. Vivostat PRF® performs better than PDGF-AB, the major PDGF isoform in human platelets. The reason for this may be that Vivostat PRF® contains multiple growth factors and not just PDGF-AB.

Data for Type 1 Procollagen

Bioactivity and stability of endogenous fibrogenic factors in platelet-rich fibrin, Lundquist R. et al., Wound Repair and Regeneration 2008; 16(3): 356-63

 

PROTECTION AGAINST PROTEOLYTIC DEGRADATION

 

The use of Vivostat PRF® in e.g. wound or orthopaedic procedures is largely dependent on the effect and stability of the PRF®-derived growth factors.

Controlling the release of platelet contents over several days requires not only a delivery media but also protection of the platelets against degradation.

The autologous fibrin matrix in Vivostat PRF® has shown to protect endogenous growth factors against proteolytic degradation and thereby preserve their biological activity.

Data on Growth Factor Levels of PDGF-ABData on Growth Factor Levels of PDGF-AB

Bioactivity and stability of endogenous fibrogenic factors in platelet-rich fibrin, Lundquist R. et al., Wound Repair and Regeneration 2008; 16(3): 356-63

 

RELEASE OF GROWTH FACTORS OVER TIME

Vivostat PRF® delivers a concentrate of growth factors embedded in a fibrin matrix.

Following application of the Vivostat PRF® solution, the fibrin matrix will naturally be broken down by fibrinolytic processes (fibrinolysis), and during this process the growth factors contained in the platelets are gradually released to the treatment site over a period of 4 days or more. In effect, the fibrin matrix is a delivery media that slowly releases growth factors over time.

IN ABDOMINAL SURGERY
Abdominal surgery covers a vast number of procedures. Many of these are performed with minimally invasive techniques, and the ability to use the Vivostat® Endoscopic Applicator has proven very useful. Vivostat® is being used in a wide range of these procedures – such as:

 

 

 

→LIVER PART RESECTION
→PANCREAS
→SPLEEN
→HERNIA MESH FIXATION
→FISTULA

 

 

Some general challenges that apply to most abdominal procedures are listed below:

  • Haemostasis
  • Sealing of the treatment area
  • Gluing e.g. hernia mesh fixation
  • Regeneration of tissue

Vivostat offers the surgeon a choice of two products which can help overcome these challenges. If haemostasis, sealing or gluing are the primary challenges, Vivostat® Fibrin Sealant is an excellent choice. If it is a combination of haemostasis, sealing, gluing and regeneration of tissue, Vivostat PRF® is the ideal product.

Vivostat Autologous Fibrin Sealant is an autologous sealant that outperforms other fibrin sealants on parameters such as polymerisation, elasticity, adhesion and impact on tissue.

Vivostat PRF® is a second generation platelet enriched product acting both as a haemostat/sealant while at the same time supporting tissue regeneration and wound healing.

VIVOSTAT PRF® IN BURNS
For decades fibrin sealant has been used for burns as a scaffold for re-epithelialization. Vivostat PRF® provides this scaffold and combines it with a high concentration of platelets relevant for tissue regeneration. 
Regenerative Medicine Skin Procedure

The high concentration of fibrin found in Vivostat PRF®, furthermore, acts as a glue enabling the surgeon to use Vivostat PRF® for graft fixations. Using Vivostat PRF® to fixate the graft allows the surgeon to use less staples or none at all depending on the location of the burn. The fibrin also acts as a haemostatic reducing the risk of haematoma formation, which may cause graft loss. Any remaining Vivostat PRF® can be applied to the graft harvest site to speed up tissue regeneration and reduce pain for the patient.

Vivostat® Applicator Kits

Skin cells/stem cells are expensive and it is crucial that they do not run off the burn or stick to the dressing. By using the Vivostat® system it is possible to glue the skin cells/stem cells to the burn with the Vivostat PRF® solution.

PRF® solution ensures that the cells stay where they are applied as the fibrin found in Vivostat PRF® polymerizes upon application.

IN CARDIAC SURGERY

For more than a decade, Vivostat® has been used in cardiac surgery. Cardiac surgeons find Vivostat® most useful for the following surgical procedures:

 

↓

 

  • Coronary artery bypass grafting (CABG)
  • Aortic anastomosis during CABG
  • Congenital heart surgery
  • Implantation of vascular prostheses
  • Operation for active endocarditis of the aortic root
  • Type A aortic dissection
  • Sternal wound healing
  • Surgery in high-risk patients, i.e. patients in anticoagulation therapy,
    Plavix therapy and diabetic patients

 

Cardiac Surgery

All though great advances in cardiac surgery have been made challenges still exist – some of these are:

  • Haemostasis of diffuse bleedings
  • Sealing of suture lines
  • Regeneration of tissue


 

Vivostat® offers the surgeon a choice of two products that can help with the above challenges. If haemostasis and/or sealing are the primary challenges, Vivostat® Fibrin Sealant is an excellent choice. If the primary challenge is tissue regeneration, Vivostat PRF® is the best choice

IN NEUROSURGERY
The Vivostat® application system possesses a number of features that are highly beneficial in neurosurgery: The Vivostat® application system offers different spray modes, e.g. “No Air” which means that it has low impact on tissue and vital organs/nerves in the skull. Furthermore, Vivostat® is applied with extreme accuracy through precision spraying.

NEUROSURGEONS MOST OFTEN CHOOSE VIVOSTAT® FOR:

 

  • Dural closure
  • Repair of dural defects
  • Spinal fusions
  • Tumor resections
  • Filler in “dead spaces”

 

 

One of the main challenges in neurosurgery is cerebrospinal fluid (CSF) leakage. Infections are another challenge. The risk of infections increases due to “dead spaces”. It is therefore preferable to fill
these with a sterile and autologous product.

Vivostat® offers the surgeon a choice of two products, which can help
overcome these challenges. If sealing, gluing and/or haemostasis
are the primary challenges, Vivostat® Fibrin Sealant is an excellent
choice. If it is a combination of sealing, gluing, haemostasis and regeneration
of tissue, Vivostat PRF® is the ideal solution.  

Vivostat Autologous Fibrin Sealant is an autologous sealant that
outperforms other fibrin sealants on parameters such as polymerisation,
elasticity, adhesion and impact on tissue.

Vivostat PRF® is a second generation platelet enriched product acting
both as a haemostat/sealant while at the same time supporting tissue

IN THORACIC SURGERY
One of the most common complications in thoracic surgery is prolonged air leakage. Fibrin sealant has been shown to reduce the incidence of prolonged air leaks and thereby enabling faster drain removal. 

 

An optimal product solution in this special surgical field provides a number of features that are important for a positive outcome:

  • The sealant must be very elastic, i.e. it must be possible to apply on a deflated lung without compromising physical properties when the lung is re-inflated
  • Polymerization must be very fast to ensure the sealant remains where applied

surgeon operating on open wound

Surgeons find Vivostat® Fibrin Sealant most useful for the following surgical procedures: 

  • Pulmonary resections
  • Extended resections
  • Post operative bronchopleural stump fistulae
  • Spontaneous pneumothorax
  • Bullous emphysema

Fibrin Sealant After Lung Resection

An added benefit of the Vivostat®system is the option of applying the special Endoscopic Applicator When using the Endoscopic Applicator, Vivostat® Fibrin Sealant is applied through the same unique nozzle as is the case with the Spraypen®. Due to the pre-bent nozzle, the spray tip can easily be pointed in many directions, offering the surgeon freedom of control of the application, which is not obtainable with conventional systems.

IN VASCULAR SURGERY

Vascular surgeons find Vivostat® Fibrin Sealant most useful for the following surgical procedures:

 

 

  • Aortic aneurysm resection

  • Peripheral bypass

  • Carotid endarterectomy

 

Fibrin Sealant has been used for centuries to handle challenges in vascular surgery such as:

  • Bleeding
  • Infections
  • Re-operations

Vivostat® Fibrin Sealant is an autologous sealant that outperforms other fibrin sealants on parameters such as polymerisation, elasticity, adhesion and impact on tissue.   

Vascular surgeons use Vivostat®  Fibrin Sealant because of its exceptional elastic and adhesive performance on the graft surface and its ability to improve haemostasis. With these product characteristics it is possible to protect the anastomosis and reduce the risk of re-operations.

Further, the surgeon is able to use Vivostat® Co-Delivery to apply a given substance with the Vivostat® Fibrin Sealant.

IN WOUND CARE
Platelets containing essential growth factors are increasingly used in treating challenging wounds. Vivostat Platelet Rich Fibrin (PRF® ) has successfully been used to treat:

 

 

  • Diabetic foot ulcers

  • Venous ulcers

  • Pressure ulcers

    • Surgical wounds

    • Skin grafts

 

The combination of platelets and fibrin in Vivostat PRF® is unique.
Not only does the fibrin protect the platelets from proteolytic degradation,
it also ensures the slow release of growth factors over time and makes
the PRF®solution polymerize immediately upon application, which means
that the platelets stay where they are applied.
Learn more about the Vivostat PRF®product characteristics here.

The Vivostat®fully automated processing system secures a consistent, high number of platelets
extracted from the patient’s own blood. Learn more about the Vivostat® system here

Vivostat A/S also offers wound care specialists the flexible wound treatment, Vivostat®Wound Therapy, that combines Growth Factors, Antibiotics and Vagus Stimulation. Vivostat®Wound Therapy consists of 3 scientifically proven techniques that separately or in a combination can effectively combat non-healing wounds!
