Abstract
Abstract A nonabsorbent holding member adapted for use within an abdominal cavity of a patient defined by an anterior wall, a posterior wall and two lateral walls to keep the patient's bowels out of the operative field during open pelvic surgery. The holding member is a substantially U-shaped planar member having a peripheral edge formed of a resiliently deformable material sized to be received within the abdominal cavity. The resilient deformation of at least a portion of the peripheral edge of the holding member results in a residual reactive force against the abdominal cavity to assist in positioning the holding member in the abdominal cavity. The peripheral edge includes a continuous groove lying in the plane of the holding member which circumscribes the elastically deformable peripheral edge to facilitate secure positioning of the holding member within the abdominal cavity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising: a U-shaped holding member adapted to be received in the patient's abdominal cavity and having a peripheral edge formed of a resiliently deformable polymer and a core formed from a polymer which has the same or greater rigidity than said resiliently deformable polymer, a resilient deformation of at least a portion of said edge of said holding member resulting in a residual reactive force against the abdominal cavity walls, said residual reactive force thereby assisting in positioning said holding member in the abdominal cavity and having a groove circumscribing said peripheral edge of said holding member.
Claim 2
Dependent Claim
123 words
Apparatus adapted for use within an abdominal cavity of a patient, said cavity defined by an anterior wall, a posterior wall and lateral walls, said apparatus comprising: a U-shaped holding member adapted to be received in the patient's abdominal cavity and having a peripheral edge formed of a resiliently deformable polymer and a core formed from a polymer which has the same or greater rigidity than said resiliently deformable polymer, a resilient deformation of at least a portion of said edge of said holding member resulting in a residual reactive force against the abdominal cavity walls, said residual reactive force thereby assisting in positioning said holding member in the abdominal cavity and having a groove circumscribing said peripheral edge of said holding member.
Claim 3
Dependent Claim
11 words
Apparatus of claim 1 wherein said edge is fabricated from foam.
Claim 4
Dependent Claim
30 words
Apparatus of claim 1 where said edge of said holding member is sized to extend beyond the cross-section of the patient's relaxed abdominal cavity to enhance said residual reactive force.
Claim 5
Dependent Claim
15 words
Apparatus of claim 1 wherein the holding member is coated by a layer of polymer.
Claim 6
Dependent Claim
13 words
Apparatus of claim 1 wherein said edge of the holding member is flat.
Claim 7
Dependent Claim
12 words
Apparatus of claim 1 wherein said holding member having a presized indentation.
Claim 8
Dependent Claim
19 words
Apparatus of claim 6 wherein said indentation is adapted to be positioned about the patient's aorta and vena cava.
Claim 9
Dependent Claim
14 words
Apparatus of claim 1 wherein said core is fabricated from a vulcanized silicone elastomer.
