<p>A suturing apparatus (100) comprises an elongated body (102), at least one arms (204) movable relative to the elongated body (102) and at least one needle (216) movable relative to the elongated body (102). The arm (204) releasably holds an end portion of a length of suture (234). The arm (204) has a sharp end portion (208) adapted to pierce an inner surface of a wall of a biological structure and pass an end portion of the suture (234) through the inner surface. The needle (216) is adapted to pierce the inner surface of such biological structure at a location proximal to the location where the end portion of the suture (234) was inserted. The needle (216) captures an end portion of the suture (234) from the arm and (234) draws the end portion of the suture (234) back through the inner surface. The end of the suture (234) is then drawn out of the biological structure by removing the elongated body (102).</p> |
