摘要:
The present invention provides an implantable prosthesis and more specifically, an implantable tubular textile prosthesis comprising a biocompatible fabric having inner and outer surfaces and first and second ends the fabric having a textile construction comprising cold drawn PTFE yarns having a substantially uniform denier and high molecular orientation. Use of cold drawn PTFE yarns result in implantable prostheses that have excellent abrasion resistance, strength and lubricity properties. Useful textile constructions include weaves, knits, braids, filament windings, spun windings and combinations thereof. The prostheses of the present invention are lubricious and have characteristics that closely resemble the properties of a natural body lumen.
