Access assembly including inflatable seal member
First Claim
1. An access assembly for insertion through tissue, the access assembly comprising:
- a flexible outer sleeve having an upper rim formed on a proximal end, a lower rim formed on a distal end and defining a longitudinal opening extending therebetween; and
an inflatable member secured within the longitudinal opening of the outer sleeve, the inflatable member including at least three inflatable lobes secured to one another at a common point prior to inflation of the inflatable lobes, adjacent lobes having sidewalls and defining a shared longitudinal slot configured to selectively receive at least one surgical device in a sealing manner, the adjacent lobes being expandable toward each other such that the sidewalls are engageable with one another.

Abstract
An access assembly for insertion through an opening in tissue is provided. The access assembly includes a flexible outer sleeve having an upper rim formed on a proximal end, a lower rim formed on a distal end and defining a longitudinal opening extending therebetween. The lower rim may define an inflatable space that in a deflated state facilitates insertion of the lower rim through tissue and in an inflated state assists in retaining the access assembly in place relative to the tissue. The access assembly further includes an inflatable member secured within the longitudinal opening of the outer sleeve. The inflatable member includes a plurality of inflatable lobes configured to selectively receive at least one surgical device therebetween in a sealing manner.
