Surgical devices and methods for forming an anastomosis between organs by gaining access thereto through a natural orifice in the body
First Claim
1. A surgical instrument for creating an anastomosis between two organs, comprising:
- a hollow outer sleeve having a distal end and a proximal end and defining a tool-receiving passage therein for receiving at least one surgical instrument therethrough, said hollow outer sleeve further having a distal pressure supply lumen and a proximal pressure supply lumen extending therethrough; and
a hollow anastomosis sleeve segment removably supported on said hollow outer sleeve adjacent said distal end thereof, said hollow anastomosis sleeve segment supporting a distal inflatable receptacle thereon in fluid communication with said distal pressure supply lumen and a proximal inflatable supply receptacle thereon in fluid communication with said proximal pressure supply lumen.

Abstract
A surgical instrument for creating an anastomosis between two organs. In various embodiments, the instrument may include a hollow outer sleeve for creating a tool-receiving passage between a natural orifice in the patient and the surgical site. The tool receiving passage may be used to operably accommodate various surgical instruments such as an endoscope, a hole-forming instrument, and suction and aeration tubes for assisting in the formation of the anastomosis. The hollow outer sleeve may further be used to position a hollow anastomosis sleeve segment within two aligned holes in the organs. The anastomosis sleeve segment supports an inflatable distal receptacle that is inflated within one of the organs and a proximal inflatable receptacle that is inflated in the other organ to retain the anastomosis sleeve segment in position. Thereafter, the hollow outer sleeve is withdrawn from the patient leaving the hollow anastomosis sleeve segment in position between the two organs.

8. A surgical instrument for creating an anastomosis between two organs comprising:
-
a hollow outer sleeve having a plurality of segments formed in a distal portion thereof that converge to form a substantially tapered distal end that can be selectively splayed open upon passage of an instrument therethrough; and an anastomosis sleeve segment removably supported on said hollow outer sleeve, said anastomosis sleeve segment supporting a distal inflatable receptacle thereon in fluid communication with a distal pressure supply lumen in said hollow outer sleeve and a proximal inflatable receptacle thereon in fluid communication with a proximal pressure supply lumen in said hollow outer sleeve. - View Dependent Claims (9, 10, 11)

12. A method for forming an anastomosis between a first organ and a second organ in a patient, comprising:
-
forming a hollow tool-receiving passage extending from a natural orifice in the patient into the first organ; supporting a hole-forming instrument within the hollow tool-receiving passage; forming a first hole through a wall of the first organ using the hole-forming instrument; forming a second hole through a wall of the second organ using the hole-forming instrument; positioning a hollow anastomosis sleeve segment having a distal inflatable receptacle and a proximal inflatable receptacle thereon within the first and second holes such that the distal inflatable receptacle is positioned within the second organ and the proximal inflatable receptacle is positioned within the first organ; inflating the distal inflatable receptacle and the proximal inflatable receptacle to retain the hollow anastomosis sleeve within the first and second holes. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
