Abrasion Resistant Prosthetic Device.

摘要

An abrasion resistant prosthetic ligament or tendon 10 includes a strap-like element 30 formed of a stable biocompatible material which is attached at opposite ends to a patient. Attached to the strap-like element are one or more protective layers having sacrificial areas 36 and 38 which are positioned in areas where abrasion between the prosthetic ligament and the patient's bones is anticipated. The sacrificial areas 36, 38 can be substantially abraided before any significant loss of strength occurs, because the sacrificial areas are non-load-bearing, and protect the strap-like element 30 from abrasion.
