System for implanting a cross-linked polysaccharide fiber and methods of forming and inserting the fiber
First Claim
1. An implant system comprising:
- a first reservoir containing a first liquid including polysaccharide;
a second reservoir containing a second liquid including an ionic cross linking agent; and
a cannula includinga first lumen in fluid communication with the first liquid in the first reservoir,a second lumen in fluid communication with the second liquid in the second reservoir,a distal end portion wherein the first and second lumens fluidly communicate with one another to mix the first and second liquids and thereby form a cross linked elongate fiber, andan opening in the distal end portion allowing passage of the cross linked fiber therethrough.

Abstract
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.

19. A method of forming an implant in a body, comprising:
-
introducing a cannula into the body, the cannula including a first lumen, a second lumen, and an opening in a distal end portion of the cannula; passing a first liquid through the first lumen, the first liquid including polysaccharide; passing a second liquid through the second lumen, the second liquid including an ionic cross linking agent; mixing the first and second liquids in the cannula to form a flexible cross linked fiber; moving the fiber through the opening in the cannula; and contacting the fiber against body tissue to allow the fiber to bend and to form the implant in the body. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
