MIT GARN UMWICKELTE ROHRFÖRMIGE PTFE PROTHESE |
摘要 |
An implantable microporous ePTFE tubular vascular graft exhibits long-term patency, superior radial tensile strength, reduction in tear propagation, and increases in suture retention strength and crush resistance. The graft includes an ePTFE tubular structure having a preselected microporous structure. The tubular structure is wrapped externally with a PTFE yarn in a helical fashion. The helical wrap of yarn is bonded to the exterior surface of the tubular structure by application of heat or heat in combination with force to form a composite structure which substantially maintains the porosity of the underlying tubular structure while increasing the suture retention strength, radial tensile strength, crush resistance, and tear propagation resistance. |
