ABSTRACT:
A novel collagen condom consists of isotropically-strong, crosslinked, regenerated fiber collagen. A method of preparation involves the steps of at least twice dipping a mandrel into an acidic collagen dispersion; slowly removing the mandrel under spinning conditions; neutralizing and drying the membrane between dippings; crosslinking the finally dried membrane while on the mandrel and removing the membrane from the mandrel.
