Abstract

Abstract The present invention provides a surgical incision or wound closure implant device possessing an interior hollow core region while maintaining the mechanical beam characteristics of the overall structure. In the case of cored biodegradable implant devices the thickness of the cored region can be varied to regulate the speed at which the device is biodegraded. The core region may optionally be filled with a medicinal agent or a stabilizing material.
