Surgical devices and methods using magnetic force to form an anastomosis
First Claim
1. A method for forming an anastomosis between first and second organs in a patient, comprising:
- forming a first opening in the first organ;
forming a second opening in the second organ;
inserting an inflatable receptacle into the second organ;
injecting a magnetic material into the inflatable receptacle to inflate the receptacle within the second organ;
positioning the second organ-adjacent to the first organ; and
using magnetic force to draw the inflated receptacle toward the first organ such that the inflated receptacle retains the second organ in sealing contact with the first organ while creating an anastomosis between the first and second organs.

Abstract
A method for forming an anastomosis between first and second organs in a patient using a hollow receptacle that is inflatable with magnetic material. The method may include forming openings through the first and second organs utilizing a hole-forming instrument inserted into the organs through a natural orifice in the patient. The hollow receptacle may be supported on a catheter assembly that is also inserted through the patient'"'"'s natural orifice and through the openings in the first and second organs and is positioned within the second organ. The hollow receptacle is then inflated with magnetic material and magnetic force is applied within the force organ to draw the inflated receptacle toward the first organ such that the inflated receptacle retains the second organ in sealing contact with the first organ while maintaining the alignment between the first and second openings to create an anastomosis between the first and second organs.

13. A method for forming an anastomosis between first and second organs in a patient, comprising:
-
inserting a hole-forming instrument through a natural orifice in the patient to form aligned holes through the first and second organs; withdrawing the hole-forming instrument out through the natural orifice; inserting a catheter assembly supporting an inflatable receptacle thereon through the natural orifice and the aligned holes to position the inflatable receptacle within the second organ; injecting the inflatable receptacle with magnetic material; using magnetic force to attract the receptacle inflated with magnetic material into sealing engagement with a corresponding portion of the first organ while maintaining the alignment between the first and second holes to create an anastomosis between the first and second organs; and withdrawing a proximal portion of the catheter assembly out through the natural orifice.

14. A surgical instrument for creating an anastomosis between two organs, comprising:
-
a catheter assembly having a distal end portion and a proximal end portion and configured for insertion through a first organ into a second organ adjacent the first organ, said catheter assembly further having a supply lumen extending therethrough; magnetic material supported within said supply lumen; an inflatable receptacle extending around a portion of said distal end portion of said catheter assembly and defining a substantially fluid-tight hollow space therebetween, wherein said space is in communication with said supply lumen and is configured to receive said magnetic material therein upon application of a pressure medium to said supply lumen; and a magnet movably receivable on a proximal portion of said catheter assembly located within the first organ such that said magnet may be positioned within the first organ and magnetically attract the receptacle inflated with said magnetic material thereto and thereby draw a portion of the second organ containing the inflated receptacle toward a corresponding portion of the first organ into sealing engagement therewith. - View Dependent Claims (15, 16, 17, 18, 19, 20)
