Abstract
A cannula assembly is utilized during a minimally invasive surgery to provide sealed access of a surgical instrument to an insufflated body cavity. The cannula assembly includes a cannula sleeve and a suction cup that is adjustably positionable on the cannula sleeve. The suction cup is formed of a compressible material such that when the suction cup is compressed or pressed against tissue by a clinician, the suction cup creates suction and engages tissue in a sealing relation.
