WHAT IS REGENERATIVE MEDICINE?

DISCOVER MORE

Regenerative Medicine encompasses many medical fields – Orthopedics and Spine Surgery, Sports Medicine, Gynecology, Urology, Oncology, Dermatology, Plastic surgery, Vascular Surgery, Cardiac surgery, etc. Regenerative Medicine is the branch of medicine that develops methods to regrow, repair or replace damaged or diseased cells, organs or tissues. Regenerative medicine includes the generation and use of therapeutic stem cells, tissue engineering and the production of artificial organs. It uses autologous blood, bone marrow or adipose components to stimulate the body’s own repair processes. A common source for regenerative cells and growth factors are bone marrow aspirate concentrate (BMAC), platelet rich plasma (obtained from one’s own blood) and adipose derived stem cells.

PATHOLOGY

DRY EYE

Dry eye is a condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Dry eye is a common and often chronic problem, particularly in older adults.

With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose. Dry eyes can occur when tear production and drainage is not in balance.

People with dry eyes either do not produce enough tears or their tears are of a poor quality:Layers of tears

  • Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.
  • Poor quality of tears. Tears are made up of three layers: oil, water and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop.

    The most common form of dry eyes occurs when the water layer of tears is inadequate. This condition, called keratoconjunctivitis sicca (KCS), is also referred to as dry eye syndrome.

People with dry eyes may experience irritated, gritty, scratchy or burning eyes; a feeling of something in their eyes; excess watering; and blurred vision. Advanced dry eyes may damage the front surface of the eye and impair vision.

Treatments for dry eyes aim to restore or maintain the normal amount of tears in the eye to minimize dryness and related discomfort and to maintain eye health.

What causes dry eyes?

Dry Eyes

Dry eyes can develop for many reasons, including:

  • Age. Dry eyes are a part of the natural aging process. The majority of people over age 65 experience some symptoms of dry eyes.
  • Gender. Women are more likely to develop dry eyes due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause.
  • Medications. Certain medicines, including antihistamines, decongestants, blood pressure medications and antidepressants, can reduce tear production.
  • Medical conditions. People with rheumatoid arthritis, diabetes and thyroid problems are more likely to have symptoms of dry eyes. Also, problems with inflammation of the eyelids (blepharitis), inflammation of the surfaces of the eye, or the inward or outward turning of eyelids can cause dry eyes to develop.
  • Environmental conditions. Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms. Failure to blink regularly, such as when staring at a computer screen for long periods of time, can also contribute to drying of the eyes.
  • Other factors. Long-term use of contact lenses can be a factor in the development of dry eyes. Refractive eye surgeries, such as LASIK, can decrease tear production and contribute to dry eyes.

THE VIVOSTAT® SYSTEM

The uniqueness of the Vivostat® system is a novel patented biotechnological process that enables reliable and reproducible preparation of autologous Fibrin Sealant or Platelet Rich Fibrin (PRF®) without using cryoprecipitation and without the need for a separate thrombin component.

THE FULLY AUTOMATED VIVOSTAT® SYSTEM CONSISTS OF THREE COMPONENTS:

  • The Processor Unit is a non-sterile, reusable, fully automated device that controls the biochemical process.
  • The Processor Unit is used to process the patient’s blood and prepare the Vivostat® Fibrin Sealant or Vivostat PRF® solution.
Vivostat Processor Product
  • The Processor Unit is operated by a single button and a display keeps the nurse informed of the remaining process time and status at all times. No specific installation is required and the large wheelbase makes moving it easy.
  • The Processor Unit can be located in any room or corridor in the operating department. It is most often placed centrally between the operating theatres. This way one Processor Unit can supply a number of operating theatres.
  • In approx.  25 min a concentrated fibrin sealant or PRF® solution is prepared from the patient’s whole blood.
  • The Applicator Unit is a non-sterile, reusable, fully automated device that controls the delivery of the Vivostat® Fibrin Sealant or Vivostat PRF®.
Vivostat Processor Product
  • The large display and integrated microprocessor automatically primes the Spraypen® and informs the surgeon of the remaining volume of fibrin sealant/PRF® throughout the entire process.
  • Different spray modes can be selected depending on the actual procedure or area to be covered. Like the Processor Unit it has a large wheelbase and can easily be moved if required.
  • The disposable set comprises of two parts: A Preparation Kit used to prepare the fibrin sealant or PRF® solution before surgery, and an Application Kit used to activate and apply the fibrin sealant/PRF® solution.

 

  • Preparation Kit
    The Preparation Kit contains the specially designed Preparation Unit – a sterile disposable device in which the patient’s blood is collected, the biochemical process carried out, and the fibrin sealant or PRF® solution harvested.

 

  • The Application Kit
    The Application Kit contains the Spraypen®1 and all other items required to prepare the system for the delivery of the fibrin sealant or PRF® solution. The Spraypen® is a sterile, disposable, hand held device which delivers the fibrin sealant or PRF® solution to the tissue. The revolutionary and patented design offers the surgeon unparalleled freedom in controlling the application unlike any other product on the market today.

 

1Besides the Spraypen®, the Vivostat® system offers different types of applicators, e.g. the Endoscopic Applicator. For a full list of application devices click here

Three easy steps to prepare Vivostat® Fibrin Sealant or Vivostat PRF®

1. Draw blood from the Patient

Fibrin Prep With Blood Inside

At the time of surgery or up to 24 hours before1, citrate (supplied with the kit) is added to the Preparation Unit. 120 ml of the patient’s own blood is then drawn into the same unit.

2. Process the patient’s blood

Vivostat Processor 800

The Preparation Unit is placed in the Processor Unit. At the touch of a button the process starts; after approx. 25 minutes, an autologous fibrin or PRF® solution is ready for use. No thrombin or bovine components are added to the blood at any time.

3. Load the Applicator Unit and spray

Vivostat Display Applicator

The Fibrin or PRF® solution is easily loaded into the Applicator Unit and applied to the surgical site using one of the unique application devices (e.g. the Spraypen). 1This depends on the type of kit being used. Always consult the “Instructions for Use” supplied with the kit to determine the correct preparation.

The following video illustrates how to prepare and apply autologous fibrin sealant.
