ABSTRACT:
Devices and methods for providing access to a body cavity without substantial loss of inflation gas therein. The device comprises an access assembly 10 that may have a tubular member 12, at least one sleeve 16 coaxially disposed over the tubular member, a pneumostasis valve 13 attached to the tubular member, and an obturator 11 removably received in the tubular member. Sleeve 16 comprises expandable region 19 capable of forming an anchor 30 upon axial compression. A method to provide access using assembly 10 comprises insertion of the assembly 10 into the body cavity, expanding region 19, and insufflating the cavity with gas. Expandable region 19 on assembly 10 is axially compressed to form anchor 30 to seal against an interior wall of the body cavity. The method may further comprise either a second expanded anchor 50 or a non-expanding anchor 40 which clamps against an exterior wall of the body cavity to securely position and seal the access assembly 10.
