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
Applicator Unit
The Disposable Set
Preparing Vivostat
The Processor Unit
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.
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.
Applicator Unit
The Applicator Unit is a non-sterile, reusable, fully automated device that controls the delivery of the Vivostat® Fibrin Sealant or Vivostat PRF®.
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
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
Preparing Vivostat
1-2-3 Spray
Three easy steps to prepare Vivostat® Fibrin Sealant or Vivostat PRF®
1. Draw blood from the Patient
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
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
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.
