Abstract
A system for delivering a flowable substance capable of changing from liquid to solid for use as implants and surgical sealants includes a first reservoir containing a first flowable substance including a bulking agent, a second reservoir containing a second flowable substance including a reacting agent, and a cannula. A method of delivering flowable substance that changes from liquid to solid for use as implants and surgical sealants includes introducing a cannula having first and second lumens into the body, passing a flowable substance including a bulking agent through the first lumen, passing a second flowable substance including a reacting agent through the second lumen, mixing the first and second flowable substances in the cannula so that the bulking agent reacts with the reacting agent to form a flexible elongated fiber in the cannula, and moving the fiber through the opening in the cannula and into the body to form at least one of an implant and surgical seal.
