Access Systems Including Collapsible Port Body For Intra-Abdominal Surgery
First Claim
1. An access system for accessing a patient'"'"'s peritoneal cavity from a body cavity accessible through a natural orifice, the peritoneal cavity and body cavity separated by an anatomical wall, said access system for use with an endoscope, said access system comprising:
- a) a tubular member having a proximal portion and a distal portion with a distal end, and a length therebetween sufficient to extend from a patient'"'"'s mouth to a patient'"'"'s stomach, said tubular member formed of a collapsible lubricious film permitting said tubular member to be at least partially collapsed in length, said tubular member defining a lumen for receiving the endoscope therethrough;
b) an anatomical wall securing system at said distal portion of said tubular member that includes expandable structure that temporarily secures said distal portion of said tubular member within a hole in the anatomical wall;
c) a handle at said proximal portion of said tubular member for operating said securing system; and
d) a coupling element for coupling said distal end of said tubular member to the endoscope.

Abstract
A natural orifice translucent endoscopic surgery (NOTES) comprises a thin, flexible body preferably made from a lubricious film. The port body also includes a coupler to removably attach the port body to an endoscope received through the port body. According to embodiments, the port body also includes a structurally modifiable port body that can be modified while the port body is within the patient. In one embodiment, the port body is constructed with a channel that preferably coils around the port body. The channel can be inflated and deflated to provide relative degrees of rigidity to the port body.

22. A system for accessing a patient'"'"'s peritoneal cavity from a body cavity accessible through a natural orifice, the peritoneal cavity and body cavity separated by an anatomical wall, said assembly comprising:
-
a) a flexible endoscope including an optical imaging system and a working channel and having a length sufficient to extend from a patient'"'"'s mouth to a patient'"'"'s stomach, the endoscope having a proximal end with a proximal handle and a distal end; and b) an access system for placement through the natural orifice of the patient and the body cavity accessible from the natural orifice, the access system including, i) a tubular member having a proximal portion and a distal portion with a distal end, and a length therebetween sufficient to extend from a patient'"'"'s mouth to a patient'"'"'s stomach, said tubular member formed of a collapsible lubricious film permitting said tubular member to be at least partially collapsed in length, said tubular member defining a lumen in which the distal portion of the endoscope is received, ii) a coupling element for coupling said distal portion of said tubular member to said distal portion of said endoscope, iii) an anatomical wall securing system at said distal portion of said tubular member that includes expandable structure that temporarily secures said distal portion of said tubular member within a hole in the anatomical wall, and iv) an access system handle at said proximal portion of said tubular member including a controller for said securing system. - View Dependent Claims (23, 24, 25, 26, 27, 28)
