Abstract
A surgical instrument, for forming an anastomosis between first and second lumens in a patient, includes a first catheter, a second catheter, a hollow needle, a guide wire, an inflatable member, and a hollow sleeve. The first catheter includes at least one first opening, which may be configured to slidably receive the hollow needle and the guide wire, which may be disposed within the hollow portion of the needle, and at least one second opening. The hollow needle includes a rotary needle. The inflatable member is mounted near the distal end of the first catheter and is in fluid communication with the second opening. The magnet is polarized such that magnetic attraction occurs perpendicular to an axis of the cylindrical body. The hollow sleeve is configured to retain at least a portion of the inflatable member, the guide wire, the hollow needle, and the magnet.
