Patent number: 9700295Abstract: A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus is configured to have different lengths. In one embodiment, the surgical includes a seal anchor member having two ends, and one of which is adapted to fold resulting in a plurality of folded states. Each folded state corresponds to a different length of the seal anchor member. The seal anchor member includes a slot to facilitate transition within the plurality of folded states. The seal anchor member further includes an aperture and a pin configured to further facilitate transition within the plurality of folded states.Type: GrantFiled: December 1, 2014Date of Patent: July 11, 2017Assignee: Covidien LPInventors: Gennady Kleyman, Gregory G.
