Fistula Repair Device with Extendable Barbs and Therapeutic Cell Delivery

摘要

A fistula repair system includes a debriding member that may be inserted into a fistula to debride the fistula wall. The debriding member may include a plurality of selectively extendable barbs. The barbs may be hollow to deliver a medical fluid within the fistula. The debriding member may also include a plurality of openings configured to communicate the medical fluid within the fistula. The barbs may extend through the openings. The openings may include associated protrusions that are configured to debride the fistula wall. The medical fluid may include a slurry of tissue and a scaffold material. The tissue in the slurry may comprise minced tissue that was harvested from the patient afflicted with the fistula. A balloon may be used to at least temporarily seal one end of the fistula. An RF probe or mechanical hook member may be used to seal the other end of the fistula.
