PolymailleFlowPlus Heparin Peripheral Bypass - 1

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.
