Gastric bypass surgery is often performed using the Endo GIA Universal Stapler, which simultaneously cuts and seals tissue by placing three lines of staples on either side of the incision. However, these staples are often unable to completely seal the tissue, and bleeding occurs along the staple-line.
Our top need is to develop a device that minimizes bleeding in laparoscopic (roux-en-y) gastric bypass surgeries in order to decrease the need for multiple sealing methods during surgery, follow-up care and/or follow-up surgery, and patient mortality rates.
