A biocompatible composite material and a method for its production are provided, wherein the composite material is made of a plastic matrix having a felt of collagen fibers contained therein, wherein the collagen fibers project out of a surface of the composite material, wherein the composite material is produced by a process involving:

Biocompatible composite material and process for its production

An improved instrument for destroying concretions within the body of living tissue, with a focusing chamber which is a part of an ellipsoid of revolution and at one focus of which shock waves are generated by arc discharge, the improvement comprising that a pad (8) filled with degassed water and of which the front and rear sides thereof (10 and 12 respectively) are composed of shape-adapting, acoustically matched thin foils, is located between the liquid-filled focusing chamber (16) and the coupling site (6) to the body (2), the pad permitting simultaneous introduction of X-rays or ultrasonic waves to locate the concretion and to monitor the success in comminuting, and a second water pad (24) similar to the first pad is located at the body decoupling site and encloses the body over a large area, the rear side thereof being fastened by means of a damping or diffusely reflecting layer (26), for instance foam rubber, to a rigid dish (28) composed of one or more parts.
