Disappearing Clips That Make Gall Bladder Surgery Safer

In laparoscopic removal of the gallbladder, a surgeon inserts a tiny video camera and operating tools through an inch-wide incision near the navel. A short hospital stay, quicker return to work, and minimal scarring have made this approach popular. But if the metal clips that are used to seal ducts and arteries become dislodged during or soon after surgery, heavy bleeding or bile leakage may result. And since metal clips don't dissolve, they can distort X-rays and MRI and CAT scans later on.

Davis & Geck International, a division of American Cyanamid, has designed a polymer clip that grips twice as tightly as metal, then is absorbed by the body. The polymer clip might also be used in hysterectomies and hernia repair, where blood vessels need to be tightly closed. Unlike the applicator used for metal clips, Davis & Geck's can be sterilized and reused, cutting down on costs and medical waste. The FDA has just approved commercial sale of the Lapro-Clip Ligating Clip, which G. Martin Wynkoop, Davis & Geck's product manager, estimates is 30% less expensive to use than metal clips.
