Abstract:
A ligation device comprising:a cannula having a proximal end, a distal end, and at least two lumens extending longitudinally from said proximal end to said distal end; a first extendable member slidably received in said first cannula lumen, said first extendable member having a distal end and being movable in said first lumen from a retracted position in which said first extendable member distal end is proximal said cannula distal end, and an extended position in which said first extendable member distal end is distal of said cannula distal end, said first extendable member including a detachable element at said first extendable member distal end; a second extendable member slidably received in said second cannula lumen, said second extendable member having a distal end and being movable in said second lumen from a retracted position in which said second extendable member distal end is proximal said cannula distal end, and an extended position in which said second extendable member distal end is distal of said cannula distal end, said second extendable member including a snare at said the distal end of the second extendable member distal end; at least one of said the first extendable member and said second extendable member including a portion which extends laterally across said cannula when said at least one of said first extendable member and said second extendable member is in said extended position; and a vessel detector located on the distal end of the cannula.
