    Abstract: The vascular graft is for implantation within a body and has a PTFE tube structure (12b) including a length and inner and outer wall surfaces. The tube structure (12b) has a non-expanded portion (50, 54, 58, 60, 64, 70, 76, 78, 84, 86, 88, 92, 94) formed from sintering a PTFE green tube extrudate and an expanded portion (23b, 24b) formed subsequent to the sintering. The expanded (24b) and non-expanded portions (50) are of the same extrudate. The expanded portion (24b) has a region which adjoins the non-expanded portion (50) wherein a degree of expansion of the region is limited by the non-expanded portion (50). The limiting of the expansion by the non-expanded portion (50) is attenuated at a location of the region which is remote from the non-expanded portion (50). A method for making the vascular graft facilitates the formation of the non-expanded and expanded portions of the PTFE tube structure.

    Abstract: An implantable composite medical device (10) having a longitudinal length a woven textile portion (26a, b) having yarns interlaced in a woven pattern, a knitted textile portion (24) having yarns interlooped in a knitted pattern. The woven and knitted portions are securably attached to one and the other to provide a composite woven and knitted textile surface along the longitudinal length of the device. Further, a crimped woven portion with a resiliently longitudinal stretchability from about 10 to about 100 linear percent over its quiescent longitudinal dimension or an uncrimped woven portion with a resiliently longitudinal stretchability of less than about 10 linear percent over its quiescent longitudinal dimension are useful. A knitted portion with a resiliently longitudinal stretchability from about 5 to about 200 linear percent over its quiescent longitudinal dimension is also useful.

The woven and knitted portions are securably attached to one and the other to provide a composite woven and knitted textile surface along the longitudinal length of the device. The woven portion may have a permeability from about 30 to about 500 m1/min/cm 2 , and the knitted portion may have a permeability from about 30 to about 15,000 m1/min/cm 2 . Further, a crimped woven portion with a resiliently longitudinal stretchability from about 10 to about 100 linear percent over its quiescent longitudinal dimension or an uncrimped woven portion with a resiliently longitudinal stretchability of less than about 10 linear percent over its quiescent longitudinal dimension are useful.
