Abstract
Prosthesis suitable for replacing or supplementing damaged ligaments or tendons are prepared from polyethylene terephthalate strips by treating such strips with a shrinking agent under restraint in the longitudinal direction. The treatment reduces substantially the extensibility of the fabric in the longitudinal direction. Stiffness can be imparted to the strips by forming the strips into tubes which may have longitudinally-extending ridges thereon and heat-setting same.
