RADIALLY EXPANDABLE TUBULAR POLYTETRAFLUOROETHYLENE GRAFTS AND METHOD OF MAKING SAME |
摘要 |
Tubular ePTFE materials which are capable of being radially expanded under the influence of a radially outward force applied from the lumen of the ePTFE tubular material to substantially uniformly radially deform the ePTFE material. The ePTFE material is radially expandable to a diameter 700 % its unexpanded diameter under the influence of pressures less than 6 atm while retaining the structural integrity of the ePTFE microstructure. Conservation of the structural integrity of the ePTFE material is determined by conservation of the ePTFE microstructure structural integrity. 00000 |
