Hemorrhoids are blood-engorged enlargements around the anus that cause discomfort, pain, and bleeding. While more than thirteen million Americans suffer from hemorrhoids, most do not undergo treatment, because current treatments are either ineffective or extremely painful.

This E-Team is developing a device that is effective yet almost painless, and can be used outside the operating room, without anesthesia. The device, which is the size of an index finger, is inserted into the anus, whereupon a Doppler sensor in its tip locates the hemorrhoidal artery, which feeds the blood-filled hemorrhoid. The device then fires a staple-like clip that compresses the hemorhoidal artery, preventing blood flow to the hemorrhoid and causing the hemorrhoid to rapidly recede completely.
