Abstract
Abstract A method for use in laparascopic surgery comprises the steps of (a) piercing an abdominal skin surface of a patient to form a hole in the skin surface, (b) inserting through the hole a tensile member, (c) lifting the abdominal wall of the patient away from a backside of the patient by exerting tension on the tensile member, and (d) drawing air into the abdominal cavity of the patient during the step of lifting.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
A method for use in laparascopic surgery to expand an abdominal cavity without positively pressurizing that cavity, comprising the steps of: piercing an abdominal skin surface of a patient to form a plurality of spaced holes in said skin surface; inserting through said holes respective tensile members; lifting the abdominal wall of said patient away from a backside of said patient by exerting tension on said tensile members; drawing air into the abdominal cavity of said patient during said step of lifting; inserting a laparoscopic instrument through at least one of said holes so that a distal end of said instrument projects into the patient's abdomen; maintaining tension on said tensile members, and thereby a predetermined elevation of the abdominal wall of said patient, during the insertion of said instrument through said one of said holes and during a subsequent surgical operation by said laparoscopic instrument; and maintaining the patient's abdomen at essentially atmospheric pressure during said surgical operation.
Claim 2
Independent Claim
159 words
A method for use in laparascopic surgery to expand an abdominal cavity without positively pressurizing that cavity, comprising the steps of: piercing an abdominal skin surface of a patient to form a plurality of spaced holes in said skin surface; inserting through said holes respective tensile members; lifting the abdominal wall of said patient away from a backside of said patient by exerting tension on said tensile members; drawing air into the abdominal cavity of said patient during said step of lifting; inserting a laparoscopic instrument through at least one of said holes so that a distal end of said instrument projects into the patient's abdomen; maintaining tension on said tensile members, and thereby a predetermined elevation of the abdominal wall of said patient, during the insertion of said instrument through said one of said holes and during a subsequent surgical operation by said laparoscopic instrument; and maintaining the patient's abdomen at essentially atmospheric pressure during said surgical operation.
Claim 3
Dependent Claim
18 words
The method recited in claim 1 wherein at least one of said tensile members is a rigid member.
Claim 4
Dependent Claim
39 words
The method recited in claim 2 wherein said rigid member is provided with means expandable from a closed configuration to an opened configuration for engaging, in said opened configuration, an enlarged area of the abdominal wall of said patient.
Claim 5
Dependent Claim
16 words
The method recited in claim 3 wherein said means for engaging includes an inflatable balloon member.
Claim 6
Dependent Claim
15 words
The method recited in claim 3 wherein said means for engaging includes a folding linkage.
