Abstract: A retention mechanism for a surgical access assembly includes a first member having a first semi-circular body with first and second ends and a second member having a second semi-circular body with first and second ends. The first end of the first member defines a first recess and the second end of the first member includes a first male connector. The first end of the second member includes a second male connector configured to be received within the first recess and the second end of the second member defines a second recess configured to receive the first male connector. When the first male connector is received within the second recess and the second male connector is received within the first recess, the first and second members are configured to frictionally engage a cannula of the surgical access assembly.

Abstract: A surgical access assembly includes a cannula including an elongated shaft and a retention anchor movable position along the elongated shaft. The retention anchor includes an annular body and a wiper disposed at a distal end of the annular body. The annular body includes a proximally-facing surface, a distally-facing surface, an outer side surface, and an inner side surface. The inner side surface defines a channel for reception and passage of the elongated shaft therethrough and the proximally-facing surface defines a proximal opening into the channel. The wiper extends radially inwardly of the inner side surface and defines a distal opening into the channel for establishing a sealed relation about the elongated shaft. The distal opening has a smaller diameter than the proximal opening.

Abstract: A surgical access assembly includes elongated cannula member having proximal end portion and a distal end portion, a cannula housing coupled to the proximal end portion of the elongated cannula member, a balloon anchor coupled to the distal end portion of the elongated cannula member, and a collar having a port disposed along the elongated cannula member and in fluid communication with the balloon anchor. The port includes a first check valve, a second check valve, an actuatable button, and a release valve. The first check valve is disposed between a first end portion of the port and a second end portion of the port thereby defining a first chamber. The second check valve is coupled to the second end portion of the port and defines a second chamber between the second check valve and the first check valve. The actuatable button is configured to control flow of air into the balloon anchor. The release valve is configured to control flow of air out of the balloon anchor.

Abstract: A surgical access device includes a cannula body and a fixation mechanism. The cannula body includes a housing, and an elongated portion extending distally from the housing and defining a longitudinal axis. The fixation mechanism includes a flange, a fixation sleeve, and a proximal sleeve. The flange is rotatable about the longitudinal axis. The fixation sleeve extends distally from the flange and radially surrounds a portion of the elongated portion of the cannula body. The proximal sleeve extends distally from the flange and radially surrounds a proximal portion of the fixation sleeve. Rotation of the flange causes a radially-expandable portion of the fixation sleeve to move between a first position defining a first gap between the radially-expandable portion and the elongated portion, and a second position defining a second, greater, gap between the radially-expandable portion and the elongated portion.

Abstract: A surgical access system includes a clip, a cannula, and an obturator. The clip includes a first housing half and a second housing half. The first and second housing halves have first end portions pivotably coupled together and second end portions having respective first and second fastener portions. The clip is movable between an open position in which the second end portions are spaced apart from each other and a closed position in which the first and second fastener portions of the second end portions are engaged with each other. The cannula and the obturator are retained between the first and second housing halves when the clip is in the closed position.

Abstract: A foldable card for retaining a plurality of surgical instruments is disclosed. The foldable card includes a first panel, a second panel hingedly connected to the first panel, a third panel hingedly connected to the second panel, a fourth panel hingedly connected to the third panel, a fifth panel hingedly connected to the fourth panel, and a sixth panel hingedly connected to the fifth panel. The first panel defines a first opening configured to allow a portion of a first surgical instrument to pass therethrough, and a second opening configured to allow a portion of a second surgical instrument to pass therethrough. The third panel defines a first opening configured to allow a portion of the first surgical instrument to pass therethrough, and a second opening configured to allow a portion of the second surgical instrument to pass therethrough.

Abstract: A surgical instrument system includes a surgical fastener applier and a positioning guide. The positioning guide includes an implant guide. The implant guide defines a guide channel configured to receive a portion of an implant to support the implant relative to the end effector to enable the surgical fastener applier to fire one or more fasteners through the implant for securing the implant to tissue.

Abstract: A surgical cannula assembly includes an elongated cannula member, first and second expandable members mounted to respective proximal and distal portions of the cannula member, and a fluid-transfer assembly. The fluid-transfer assembly includes proximal and distal flanges coupled to the proximal portion of the cannula member. The first expandable member is disposed between the proximal and distal flanges such that movement of one of the proximal or distal flanges along the cannula member adjusts a pressure applied by the proximal and distal flanges on the first expandable member to transfer an inflation medium between the first and second expandable members.
