Abstract

A seal anchor member defines a housing defining a longitudinal axis, the housing having leading and trailing ends, and including a plurality of lumens extending between the leading and trailing ends, each lumen being adapted for substantially sealed reception of an object therein and defining a longitudinal axis, wherein at least two of the lumens define longitudinal axes that are non-parallel to facilitate angled, at-rest placement of multiple instruments within the seal anchor member.

Claims

1. A surgical device comprising:

a compressible housing defining a longitudinal axis, the compressible housing having arcuate leading and trailing ends;

the compressible housing defining a plurality of lumens extending between the leading and trailing ends, each lumen defining an axis, wherein at least a portion of each lumen is adapted to expand to accommodate an instrument in a substantially sealed manner, and wherein, in an at-rest condition, the axis of a first and the axis of a second lumen are nonparallel with respect to each other and with respect to the longitudinal axis of the compressible housing and a third lumen is parallel to the longitudinal axis of the compressible housing;

the compressible housing comprising a leading structure defined in at least one of the leading and trailing ends of the compressible housing, the leading structure extending linearly outward from at least one of proximal and distal ends of two of the plurality of lumens, the leading structure configured to lead an instrument into one of the two of the plurality of lumens, wherein the leading structure extends outward from the two of the plurality of lumens.

2. The surgical device of claim 1, wherein the compressible housing comprises an intermediate portion having a proximal section that tapers inwardly in a distal direction and a distal section that tapers outwardly in the distal direction.

3. The surgical device of claim 1, wherein the leading structure is at least one of a groove and a cut-out.

4. The surgical device of claim 1, wherein the compressible housing is formed from at least one of a foam and a gel.

5. The surgical device of claim 4, wherein the compressible housing is formed from polyisoprene, urethane or silicone.

6. The surgical device of claim 1, wherein the compressible housing is configured to help maintain insufflation pressure in a body cavity during a minimally invasive laparoscopic surgical procedure.

7. The surgical device of claim 1, further comprising an insufflation tube.
