摘要 |
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 t he 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 th e fully deployed position. Methods for providing anchored access to a cavity within a patient are also disclosed.
