Patent number: 9326761Abstract: An access device includes a body, a first tube, a second tube, and a mechanism. The first and second tubes extend through the body. The mechanism operably couples the first and second tubes such that at least one tube is pivotable about an axis with respect to the other tube. The body may form a substantially fluid-tight seal at the incision. In another embodiment, the access device further includes a third tube extending through the body and the mechanism operably couples the tubes together such that at least two tubes are pivotable about the axis with respect to the remaining tube.Type: GrantFiled: December 10, 2013Date of Patent: May 3, 2016Assignee: Covidien LPInventors: Thomas Wingardner, III, Gene A.

Publication number: 20140303640Abstract: A specimen retrieval pouch (pouch) is provided. The pouch including a closed bottom portion, an open upper portion and an elongated tube operably coupled to an interior wall of the pouch. The elongated tube has a plurality of openings positioned along a length thereof. A suture accessible at a proximal end of the pouch is positioned within the elongated tube and extends past a distal end thereof. The suture is movable within the elongated tube and relative to the pouch. The suture has either a needle or a loop at a distal end thereof for attaching to tissue and subsequently drawing the tissue into the pouch when the suture is pulled. One or more reinforced tabs are operably disposed on the pouch. The reinforced tab(s) is/are configured to be grasped by a user to provide a counter pull force as the suture is being pulled through the elongated tube.Type: ApplicationFiled: June 23, 2014Publication date: October 9, 2014Inventors: Emily Davis, Thomas Wingardner, III, Russell Pribanic
