Abstract
Apparatus and methods for providing access to a body cavity without substantial loss of inflation gas therein. The apparatus includes an access assembly that has a tubular member having a proximal end, a distal end, an elastic portion interposed the proximal end and the distal end, and a lumen therethrough. An anchor sleeve is disposed coaxially over the tubular member and has a radially expandable region. The anchor sleeve is moveable between an axially elongated configuration and an axially shortened configuration and is biased toward the axially shortened configuration by a force exerted by the elastic portion of the tubular member. The axially shortened configuration corresponds to the anchor sleeve being in the fully deployed position. Methods for providing anchored access to a cavity within a patient are also disclosed.
