Abstract
Abstract A system and method for delivering a surgical clip to a surgical site within a patient's body to compress body tissue is disclosed. In one embodiment for the system of the present invention, the system includes an endoscopic device that has an endoscope cap disposed on a distal end of the endoscopic device. A surgical clip is removably disposed on an outside surface of the endoscope cap. A deployment device is associated with the surgical clip for deploying the surgical clip from the endoscope cap to the body tissue that is to be compressed. The surgical clip can be a deformable clip that is deployed in a non deformed configuration, and is then deformed so as to apply compression on selected tissue. The surgical clip can be a multi legged clip, having a plurality of legs that can be locked in a closed position to apply compression to body tissue.
