Abstract:
1. A surgical instrument for forming an anastomosis between two lumens, the surgical instrument comprising: a first catheter comprising a proximal end, a distal end, at least one first opening and at least one second opening, the at least one first opening configured to slidably receive a hollow needle from the proximal end to the distal end of the first catheter; a hollow sleeve slidably receivable over the distal end of the first catheter; a magnet defining an opening there-through, wherein the magnet is retained within the hollow sleeve; an inflatable member mounted near the distal end of the first catheter and in fluid communication with the at least one second opening, wherein the inflatable member is configured to pass through the opening of the magnet when the inflatable member is in a deflated state, retain the magnet when the inflatable member is in an inflated state, wherein the hollow sleeve retains at least a portion of the inflatable member in an inflated state, wherein the hollow sleeve is slidably removable from the magnet and the inflatable member, and be removed from the magnet when the inflatable member is in a deflated state; and wherein the inflatable member is inflatable to an inner diameter of the hollow sleeve, wherein the hollow sleeve prevents over inflation of the inflatable member, and wherein the inflatable member may be deflated when the hollow sleeve is slidably removed from the magnet and inflatable member.
