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 flexible seal anchor member defining a longitudinal axis and comprising an arcuate distal surface, an arcuate proximal surface, and an intermediate portion extending therebetween, wherein the intermediate portion has a proximal section that tapers inwardly in a distal direction and a distal section that tapers outwardly in the distal direction;

the seal anchor member further comprising a protruding portion disposed along a periphery of each of the arcuate proximal surface and the arcuate distal surface;

the seal anchor member defining at least a first lumen, a second lumen and a third lumen extending from the arcuate proximal surface and through the intermediate portion to the arcuate distal surface, wherein the first lumen is parallel relative to the longitudinal axis of the seal anchor member and the second and third lumen are non-parallel relative to the longitudinal axis of the seal anchor member; and

wherein at least one of the arcuate proximal surface or the arcuate distal surface defines first and second cutouts, the entire first cutout extending linearly outward from the second lumen in a first direction and the entire second cutout extending linearly outward from the third lumen in a second direction.

2. The surgical device of claim 1, wherein the anchor seal member comprises at least one of a pliable, compressible and a shape memory material.

3. The surgical device of claim 1, wherein at least one of the arcuate proximal surface or the arcuate distal surface is concave.

4. The surgical device of claim 1, wherein at least one of a relative position or shape of at least a portion of at least one of the first, second, or third lumen is adjustable by a force exerted by a surgical instrument.

5. The surgical device of claim 1, wherein the seal anchor member is adapted to transition between a first condition in which at least a portion of the seal anchor member is insertable within an opening in a body of a patient, and a second condition in which at least a portion of the seal anchor member is in substantial sealing relation with tissue surfaces defining the opening.

6. The surgical device of claim 1, wherein at least one of the first or second cutouts is configured to facilitate stabilization of a surgical instrument.

7. The surgical device of claim 1, wherein at least a portion of at least one of first lumen, second lumen, or third lumen is configured for sealed reception of a surgical instrument.

8. The surgical device of claim 1, wherein the seal anchor member is configured for insertion into an opening during a laparoscopic surgical procedure, and wherein at least one of the first lumen, second lumen, or third lumen is configured to inhibit escape of insufflation gases from within a body cavity.

9. The surgical device of claim 1, further comprising an insufflation tube positioned within at least one of the first lumen, second lumen, or third lumen.

10. A surgical device comprising:

a flexible seal anchor member defining a longitudinal axis and comprising a first surface, a second surface and a body extending therebetween;

the seal anchor member defining at least a first port, a second port and a third port extending from the first surface and through the seal anchor member to the second surface, wherein at least a portion of at least one of the first port, second port, or third port is transitionable between a closed configuration to an open configuration upon introduction of an instrument;

wherein at least one of the first or second surfaces defines first and second cutouts, the entire first cutout extending linearly outward from the second port in a first direction and the entire second cutout extending linearly outward from the third port in a second direction; and

an insufflation tube positionable within at least one of the first port, the second port, and the third port.

11. The surgical device of claim 10, wherein the first port is parallel to the longitudinal axis and the second and third ports are each nonparallel to the longitudinal axis.

12. The surgical device of claim 10, wherein the first surface is the same shape and size as the second surface and, at least one of the first or second surfaces includes a protruding edge extending about its circumference.

13. The surgical device of claim 10, wherein the first cutout and a portion of the second port defines an elliptical shape.

14. The surgical device of claim 10, wherein the first and second surfaces are arcuate.

15. The surgical device of claim 10, wherein the anchor seal member comprises at least one of a pliable, compressible and a shape memory material.

16. The surgical device of claim 10, wherein at least one of a shape or a position of at least part of at least one of the first, second or third ports is adjustable by a force exerted by the introduction of the instrument.

17. The surgical device of claim 10, wherein a cross section of the body taken perpendicular to the longitudinal axis and at the midpoint between the first and second surfaces has a smaller area than the area of either the first surface or the second surface.

18. The surgical device of claim 17, wherein the body has a proximal section that tapers inwardly in a distal direction and a distal section that tapers outwardly in the distal direction.

19. The surgical device of claim 10, wherein the first and second cutouts are configured to lead the instrument into the respective second and third ports.
