about the product


Unique Formulation

InQu’s composition of a resorbable polymer, PLGA, integrated with a biologic molecule, hyaluronic acid, creates a biosynthetic scaffold ideal for bone regeneration.

Tailored Resorption Time

PLGA provides a biopolymer scaffold with a resorption profile tailored to match the rate of new bone formation.

Rapid Cell Binding

Hyaluronic acid creates a cell-friendly microenvironment with a favorable pH, allowing InQu to bind up to 78% of MSCs within 20 minutes.

InQu Bone Graft Extender & Substitute combines a biologic molecule with the consistency and cost effectiveness of a synthetic to create a new category of bone graft: Biosynthetic.

Proven Efficacy

Clinically proven fusion rates of 94%, outperforming fusion rates for ICBG at 12 months.


Integrated PLGA and hyaluronic acid creates a cell-friendly microenvironment, binding MSCs and growth factors.

Success in Complex Cases

Demonstrated robust fusion, even in challenging high-risk patients.

Faster Fusion

Shorter time to fusion vs. traditional synthetic bone grafts AND superior overall fusion rates at 12 months: 93% vs. 68%

Use with Confidence

InQu offers a cost-effective, on-label solution for fusion throughout the spine.

Exceptional Handling

A cohesive, moldable putty providing ease-of-use for a variety of applications.

A Faster Path to Healing

InQu partners with the body’s natural processes to form bone in a shorter period of time without inciting an immune response. In contrast, traditional synthetics rely on inflammation and recruitment of specialized cells to digest the mineral scaffold before new bone formation can begin.

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 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.
