Access assembly including inflatable seal member

摘要

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.

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 positionable within the longitudinal opening of the flexible outer sleeve, the inflatable member including a first inflatable lobe attached to a second inflatable lobe at a common point prior to inflation of the first and second inflatable lobes, the first inflatable lobe and second inflatable lobe defining a shared longitudinal slot therebetween configured to selectively receive at least one surgical device therethrough, the first inflatable lobe expandable toward the second inflatable lobe and inflatable independently from the second inflatable lobe.
