Composite Medical Textile Material and Implantable Devices Made Therefrom

Abstract

An implantable composite medical device having a longitudinal length a woven textile portion having yarns interlaced in a woven pattern, a knitted textile portion 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. The woven portion may have a permeability from about 30 to about 500 ml/min/cm 2 , and the knitted portion may have a permeability from about 30 to about 15,000 ml/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. A knitted portion with a resiliently longitudinal stretchability from about 5 to about 200 linear percent over its quiescent longitudinal dimension is also useful.
