System for implanting a cross-linked polysaccharide fiber and methods of forming and inserting the fiber

摘要

Systems and methods are disclosed for implanting and forming both a polysaccharide fiber and an implant formed of the fiber. In one system, a liquid including polysaccharide and a liquid including a cross linking agent are mixed in a cannula to form a cross linked polysaccharide fiber in the cannula. In another system, a carrier fluid delivers a previously manufactured fiber through a cannula. A cutter is optionally provided on the cannula to sever the fiber after a sufficient length of fiber is implanted. The disclosed methods include a method of forming a polysaccharide fiber in the cannula while the cannula is inserted in a body, and a method of making a cross linked polysaccharide fiber for loading in a delivery system.
