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 seal anchor member, comprising:

a housing, the housing including a leading end and a trailing end, the housing defining a longitudinal axis; and

one or more lumens extending through the leading and trailing ends, the one or more lumens each being adapted for substantially sealed reception of an instrument therein, the one or more lumens defining an axis that is non-parallel with respect to the longitudinal axis of the housing in the absence of a force applied to the housing.

2. A seal anchor member, comprising:

a housing, the housing including leading and trailing ends; and

a plurality of lumens extending through the leading and trailing ends, each lumen being adapted for substantially sealed reception of an instrument therein, and defining an axis, wherein, in the absence of a force applied to the housing, at least two of the lumens define axes that are intersecting relative to each other when the housing is viewed in a side cross-sectional view.

3. A seal anchor member, comprising:

a housing, the housing including leading and trailing ends, the housing defining a longitudinal axis; and

a plurality of lumens extending through the leading and trailing ends, each lumen being adapted for substantially sealed reception of an instrument therein, wherein at least two of the lumens are straight and non-parallel relative to each other.

4. The seal anchor member of claim 3, wherein the lumens are laterally spaced apart.

5. The seal anchor member of claim 3, wherein the housing is formed from a compressible material, the instrument inserted within the lumen defines an angle with respect to the longitudinal axis of the housing, the angle being adjustable.

6. The seal anchor member of claim 3, wherein the lumens are non-parallel with respect to one another in the absence of a radial force exerted instruments received within the lumens.

7. The seal anchor member of claim 3, wherein the leading end includes a groove adjacent a proximal end of at least one of the lumens, the groove being adapted to stabilize instruments inserted into the at least one of the lumens.

8. The seal anchor member of claim 7, wherein the groove is generally arcuate.

9. The seal anchor member of claim 7, wherein the groove extends radially outward from the proximal end of at least one of the lumens.

10. The seal anchor member of claim 3, wherein the housing is adapted to transition between a first compressed condition to facilitate at least partial insertion of the seal anchor member within a tissue tract, and a second condition to facilitate securing of the seal anchor member within the tissue tract and in substantial relation with tissue surfaces defining the tissue tract.

11. The seal anchor of claim 3, wherein the housing defines a substantially hour-glass shape.

12. The seal anchor of claim 3, wherein the leading and trailing ends each has an arcuate configuration.

13. The seal anchor of claim 3, wherein proximal ends of the lumens are radially spaced apart about the trailing end.
