Abstract
An endoscopic tissue grasper device includes a flexible tubular member, a flexible shaft extending through the tubular member, a proximal handle for moving the shaft and tubular member relative to each other, and a distal helical coil having a sharpened end for engaging tissue. The tissue grasper is advanced through a working channel of an endoscope, engaged relative to tissue, and retracted to pull tissue into a path of a movable needle coupled at a distal end of the endoscope so that the needle can be passed through the tissue. The needle is preferably provided with a suture so that as the needle is passed through the tissue a stitch is formed.
