In vivo performance of a new biodegradable polyester urethane system used as a nerve guidance channel

Patrick Aebischer

Biodegradable nerve guidance channels (NGCs) represent a promising alternative to current clinical nerve repair procedures. To be suitable as a NGC material, the polymer system should possess elastomeric properties and degrade at a defined rate without int ...
