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.

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.

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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
