Abstract

A percutaneous in-vig venous model was characterized by testing platelet deposition on standard vascular prosthetic materials in the baboon. The model detected significant difference in platelet deposition on ePTFE compared to Dacron. Low molecular weight dextran was administered following a baseline test period. A significant decrease in platelet depositionr occurred for both materials and coincided with a prolongation in bleeding time. No consistent decrease was found in control experiments which used no bolus or a saline bolus for treatment. Advantages of the model included ease of use and adaptability to test large numbers of materials. The model was suItable for in-vivo screening of platelet interactions with biomaterials placed in the bloodstream.
