Abstract
Abstract A method of placing a tube through a body wall into a hollow body organ is provided. The method includes performing a laparoscopy, inserting a plurality of retraction device introducers through the body wall, fixing a like plurality of retraction devices to the body wall by means of the retraction device introducers, fixing the body organ to the interior surface of the body wall and inserting a tube through the body wall into the organ; and fixing the tube to the organ. In two applications, the method may be used with gastrostomy or jejunostomy.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
A method of placing a tube in a hollow body organ through a body wall having an interior surface juxtaposed with the body organ and separated therefrom by a space and an exterior surface outside the body comprising the steps of: (a) performing a laparoscopy through the body wall in a location so as to bring the organ under direct vision; (b) inserting a plurality of retraction device introducers through said body wall and into said space and into said organ under direct vision; (c) fixing a like plurality of retraction devices to said organ by means of said introducers; (d) fixing said body organ in contacting relation with said interior surface by means of said retraction devices; (e) inserting a hollow tube through said body wall into said body organ; and (f) fixing said tube in said body organ.
Claim 2
Independent Claim
140 words
A method of placing a tube in a hollow body organ through a body wall having an interior surface juxtaposed with the body organ and separated therefrom by a space and an exterior surface outside the body comprising the steps of: (a) performing a laparoscopy through the body wall in a location so as to bring the organ under direct vision; (b) inserting a plurality of retraction device introducers through said body wall and into said space and into said organ under direct vision; (c) fixing a like plurality of retraction devices to said organ by means of said introducers; (d) fixing said body organ in contacting relation with said interior surface by means of said retraction devices; (e) inserting a hollow tube through said body wall into said body organ; and (f) fixing said tube in said body organ.
Claim 3
Dependent Claim
45 words
The method of claim 1 wherein step (e) of said claim comprises: (a) inserting a tube introducer through said body wall and into said organ; (b) passing a tube having a balloon thereon over said tube introducer until said balloon is within said hollow organ.
Claim 4
Dependent Claim
37 words
The method of claim 2 wherein step (f) of claim 1 comprises the steps of: (a) inflating said balloon so as to fix said tube within said organ; and (b) withdrawing said tube introducer from said body.
Claim 5
Dependent Claim
31 words

Claim 6
Dependent Claim
22 words
The method of claim 4 further including the steps of using a series of progressively larger dilators to progressively enlarge said hole.
Claim 7
Dependent Claim
28 words
The method of claim 1 including the step of withdrawing said retraction device introducers from said body after the step of fixing said retraction devices to said organ.
Claim 8
Dependent Claim
25 words
The method of claim 1 including the step of insufflating the body organ prior to the step of fixing said plurality of retraction devices thereto.
Claim 9
Dependent Claim
16 words
The method of claim 1 further including the withdrawal of said tube introducer from said body.
Claim 10
Dependent Claim
30 words
