1. A seal anchor member, comprising:
- a housing, the housing including leading and trailing ends, the housing defining a longitudinal axis along a length of the seal anchor member, the length extending between the 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, wherein at least two of the lumens are straight and non-parallel relative to each other, the trailing end defining a substantially linear groove leading into at least one of the plurality of lumens, wherein the substantially linear groove extends radially outward from an end portion of the at least one of the plurality of lumens, the substantially linear groove defined entirely within the trailing end, wherein the linear groove linearly extends orthogonal to the longitudinal axis of the housing, wherein the linear groove has a cylindrical configuration.

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.

14. A surgical device comprising:
-
a seal anchor member, the seal anchor member including a leading end defining a distal-most surface and a trailing end defining a proximal-most surface, the seal anchor member defining a longitudinal axis, the seal anchor member defining 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 plurality of lumens are straight and non-parallel relative to each other and to the longitudinal axis when the seal anchor member is in an at-rest condition, wherein a proximal-most portion of the seal anchor member is arcuate and defines a stabilization structure proximal to at least one of the plurality of lumens to stabilize the instrument as the instrument is being inserted into the at least one of the plurality of lumens wherein at least a portion of the stabilization structure is disposed radially inward of at least one of the plurality of lumens, wherein the stabilization structure includes a non-circular transverse cross-section, wherein the stabilization structure has a half-cylindrical configuration. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
