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 housing including proximal and distal ends, the housing defining a central longitudinal axis and at least three lumens extending between the proximal and distal ends, the at least three lumens being straight and non-parallel with respect to each other and with respect to the central longitudinal axis, each lumen of the at least three lumens configured for sealed reception of a surgical object inserted therethrough, the housing including a structure configured to stabilize the surgical object inserted through one lumen of the at least three lumens, wherein the entire structure is disposed in the proximal end, the entire structure extending outwardly from the one lumen of the at least three lumens in a single direction transverse with respect to a central longitudinal axis of the one lumen of the at least three lumens.

2. The surgical device according to claim 1, wherein the at least three lumens are non-parallel with respect to each other and with respect to the central longitudinal axis of the housing in the absence of a force applied to the housing.

3. The surgical device according to claim 1, wherein the housing includes a compressible material, whereby the housing is transitionable between an expanded condition and a compressed condition for insertion and securement of the housing within an opening.

4. The surgical device according to claim 1, wherein the housing includes at least one of a compressible or a shape memory material.

5. The surgical device according to claim 1, wherein the housing includes at least one of a foam or a gel.

6. The surgical device according to claim 1, wherein the structure is a cutout.

7. The surgical device according to claim 6, wherein the cutout is arcuate.

8. The surgical device according to claim 1, wherein the housing has an hourglass shape.

9. The surgical device according to claim 1, wherein each lumen of the at least three lumens is configured to inhibit escape of insufflation gases from within a body cavity in the absence of the surgical object inserted therein.

10. The surgical device according to claim 1, wherein the at least three lumens are laterally space apart adjacent the proximal end of the housing.

11. A surgical device comprising:

a housing formed of a compressible material, the housing having a proximal end, a distal end, and an intermediate portion including a proximal section that tapers inwardly in a distal direction and a distal section that tapers outwardly in the distal direction;

the housing defining a central longitudinal axis and at least three lumens extending between the proximal and distal ends, the at least three lumens being non-parallel with respect to the central longitudinal axis of the housing, the housing including at least one insertion feature disposed entirely in the proximal end of the housing, the at least one insertion feature extending outwardly in a single direction from a proximal end of at least one of the at least three lumens, the at least one insertion feature adapted to lead an instrument into the at least one of the at least three lumens and wherein the single direction is transverse to a central longitudinal axis of the at least one of the at least three lumens.

12. The surgical device according to claim 11, wherein the at least one insertion feature is one of a cutout or a groove.

13. The surgical device according to claim 11, wherein each lumen of the at least three lumens defines an axis, the axes of the at least three lumens are non-parallel with respect to each other.

14. The surgical device according to claim 13, wherein the axes of the at least three lumens are non-parallel with respect to each other in the absence of a force applied to the housing.

15. The surgical device according to claim 11, wherein the housing is formed from at least one of polyisoprene, urethane, or silicone.
