INFLATABLE ACCESS ASSEMBLY
An assembly for accessing a body cavity through an opening in tissue is provided. The access assembly includes a base having a substantially cylindrical compressible member defining at least a first lumen configured to receive a surgical instrument therethrough. The access assembly further includes an inflatable sleeve secured about the base. The inflatable sleeve is configured to selectively retain the access assembly with an opening in tissue.
1 . An access assembly comprising:
a base including a substantially cylindrical compressible member defining at least a first lumen extending therethrough; and
an elongated, generally cylindrical inflatable sleeve connected to and positioned circumferentially around the base, the inflatable sleeve having an inner surface to which the base is generally transverse, the inflatable sleeve being configured to selectively retain the access assembly within an opening in tissue.
2 . The access assembly of claim 1 , wherein the inflatable sleeve includes upper and lower rims.
3 . The access assembly of claim 1 , wherein at least on of the inflatable sleeve and base is composed of at least one of silicone, thermoplastic elastomers (TPE), rubber, foam, gel.
4 . The access assembly of claim 1 , wherein the base is selectively secured about the base.
5 . The access assembly of claim 1 , wherein the base is securely affixed to the base by adhesive, welding, bonding or mechanical fasteners.
6 . The access assembly of claim 1 , wherein the base includes at least one valve member in the at least first lumen.
7 . The access assembly of claim 1 , wherein the opening in the tissue is an incision.
8 . The access assembly of claim 1 , wherein the opening in tissue is a natural orifice.
9 . The access assembly of claim 1 , wherein the inflatable sleeve includes an inflated condition and a deflated condition.
10 . The access assembly of claim 1 , wherein the inflatable sleeve includes at least a first inflatable portion and a second inflatable portion.
11 . The access assembly of claim 10 , wherein the inflatable sleeve further includes a third inflatable portion.
12 . The access assembly of claim 1 , wherein the inflatable sleeve includes an inflation port configured for operable connection with a source of inflation fluid.
