Abstract:
A method for establishing an end-to-side anastomosis between a severed end of a first hollow organ and a side-wall of a second hollow organ, the method comprising:(a) introducing a catheter, having proximal and distal ends, into the first hollow organ and passing the catheter through the first organ until the distal end of the catheter is substantially adjacent to the severed end of the first hollow organ, the catheter having a selectively operable cutter adapted to remove a portion of the side-wall of the second hollow organ;(b) positioning the severed end of the first hollow organ in proximity with the site for anastomosis of the second hollow organ;(c) adhering the severed end of the first hollow organ to the side-wall of the second hollow organ, thereby defining a region of securement on a side-wall of the second hollow organ; and(d) activating the cutter to remove a portion of a side-wall of the second hollow organ thereby creating an opening within the region of securement defined by the engagement of the severed end of the first hollow organ with the side-wall of the second hollow organ.
