Abstract

A device for accessing a body cavity through an opening in tissue is provided. The access device includes a unitary compressible body configured to be received in an opening in tissue. The compressible body includes a central portion, an upper rim located on a proximal end of the body and a lower rim located on a distal end of the body. The central portion defines a slit configured to permit the passage of a hand therethrough in a sealing manner.

Claims

1. An access device for insertion through an opening in tissue, the access device comprising:

a body formed of a foam material, the body having;

a central portion with a proximal end and a distal end;

an upper rim located on the proximal end of the central portion; and

a lower rim located on the distal end of the central portion,

at least one of the upper rim or the lower rim having an oval cross-section relative to a longitudinal axis of the body when the body is in an at-rest state, the at least one of the upper rim or the lower rim defining a major axis and a minor axis, the body transitionable between a compressed condition adapted to facilitate insertion thereof through the opening in the tissue and an uncompressed condition adapted to secure the body within the opening in the tissue in a sealing relation, the at least one of the upper rim or the lower rim defining a slit between the upper and lower rims of the body, wherein the slit extends a substantial length of the at least one of the upper rim or the lower rim along the major axis, the slit extending between proximal and distal ends of the body.

2. The access device according to claim 1, wherein the central portion includes an oval cross-section.

3. The access device according to claim 1, wherein the body defines an hourglass shape.

4. The access device according to claim 1, wherein the upper and lower rims are integrally formed with the central portion.

5. The access device according to claim 2, wherein the central portion has the oval cross-section when the body is in the at-rest state.

6. The access device according to claim 1, wherein the oval cross-section of the at least one of the upper rim or the lower rim is transverse to the longitudinal axis of the body.
