Product catalog summary
Overview: The document discusses the PM FLOW Plus Heparin bioactive coating applied to ePTFE vascular prostheses. This coating provides a dual mechanism of action: an antithrombogenic effect and reduced neointimal hyperplasia, enhancing hemocompatibility and preventing stenosis and thrombosis.
Antithrombogenic Effect: The Heparin coating binds to antithrombin III (AT III), causing a conformational change that activates AT III. This activation leads to the inactivation of thrombin and Factor Xa, preventing clot formation. The coating ensures significant coagulation inhibition on the luminal surface for at least seven days.
Reduced Neointimal Hyperplasia: Heparin is known to reduce neointimal hyperplasia, which helps prevent progressive perianastomotic stenosis that could lead to late thrombosis.
In-Vivo Study: A comparative study on pigs demonstrated the long-lasting antithrombogenic activity of the PM FLOW Plus Heparin prosthesis. No thrombus formation was observed in the anastomosis and medial areas of the PM FLOW Plus Heparin prosthesis, unlike the control ePTFE.
Clotting Time Evaluation: The PM FLOW Plus Heparin prosthesis showed a significant reduction in whole blood clotting time compared to conventional ePTFE grafts, indicating its superior thromboresistance.
Product Specifications: The prosthesis is available in various sizes and diameters, with options for thin wall and helical reinforcement. It is CE marked, ensuring compliance with European standards.
Conclusion: The PM FLOW Plus Heparin bioactive coating offers a durable and effective solution for peripheral vascular reconstructions, providing enhanced antithrombogenic properties and reduced risk of neointimal hyperplasia.

ePTFE vascular prosthesis with B ioactive luminal coating with double mechanism of action 1 ) Antithrombogenic effect for advanced hemocompatibility Injured vessel Initiation phase Fibrinogen Cross-linked Fibrin Clot Propagation phase Clot formation PM FLOW Plus Heparin Inhibition of Thrombin Propagation phase Cross-linked Fibrin Clot Heparin binds to the antithrombin  III (AT III) thanks to its bioactive site causing its conformational change and its activation. The activated AT III then inactivates proteases involved in blood clotting, most notably thrombin and Faxtor Xa. A : The formation of a complex between AT III, thrombin, and heparin results in the inactivation of thrombin. B : The conformational change in AT III on heparin-binding lead to its inhibition effect on factor Xa. Prevention of thrombosis and blood clot formation R 2 ) educed neointimal hyperplasia Heparin molecule is known to reduce neotimal hyperplasia phenomenon (1). Thus PM FLOW Plus Heparin bioactive coating helps to prevent progressive perianastomotic stenosis development which could lead to late thrombosis.
