Abstract:
A method for forming an anastomosis between first and second adjacent hollow viscera, comprising the steps of:(a) selecting the area where the anastomosis is to be formed; (b) providing a tract from outside of the body, to the interior of the first hollow viscus and through the adjacent walls of the first and second hollow viscera in the area where the anastomosis is to be formed; (c) providing an anchor assembly comprising a suture having a stationary anchor secured to its distal end and a sliding anchor slidably attached to the suture proximal to the stationary anchor; (d) attaching said sliding anchor to said suture such that it does not move relative to the suture unless a force is applied to the sliding anchor in a direction longitudinally along the suture; (e) positioning the anchor assembly, through said tract, in the area where the anastomosis is to be formed; (f) depositing said stationary anchor in said second hollow viscus; (g) depositing said sliding anchor in said first hollow viscus; (h) placing the anchor by applying a force to said sliding anchor through said track to position said sliding anchor against the wall of said first hollow viscus with the adjacent walls of the viscera held flush together between the stationary and sliding anchors; (i) providing a tract from outside of the body, through which the anastomosis is to be formed, to the area where the anastomosis is to be formed and adjacent to where the walls of the viscera have been anchored together; (j) piercing the adjacent walls of the hollow viscera in the area where the anastomosis is to be formed and adjacent to where the anchor was placed; (k) dilating the aperture formed by piercing the adjacent walls of the hollow viscera to form the anastomosis of the size desired.
