Abstract: A surgical access device includes a cannula body, a fixation mechanism, and an illumination mechanism. The fixation mechanism includes a collar, a sleeve, an expandable member, and a distal ring. The illumination mechanism includes at least one light disposed on the expandable member, and a switch. Distal translation of the collar relative to an elongated portion of the cannula body causes the expandable member to move from a first position defining a first gap between a mid-portion of the expandable member and the elongated portion of the cannula body, to a second position defining a second gap between the mid-portion of the expandable member and the elongated portion of the cannula body, the second gap being greater than the first gap.

Abstract: An evacuation adapter for use with a surgical access device includes a distal section selectively engageable with a proximal section. The distal section and the proximal section each include a base, an outer ring, and an inner ring. Each base defines a central opening. Each outer ring defines at least one opening. Each inner ring defines at least one opening. The outer ring of the proximal section includes a port. The proximal section is rotatable relative to the distal section between a first position where fluid is able to flow from the central opening of the distal section through the port, and a second position where fluid is blocked from flowing from the central opening of the distal section through the port.

Abstract: A surgical access device includes a check valve having baffling discs, a tube, and a housing. The housing has first and second housing halves. Baffling discs are configured to form a lumen. Each baffling disc is a conical annulus and is stacked adjacent to another baffling disc and spaced apart via spacers disposed on each baffling disc. The spacers help define a first gap between adjacent baffling discs for defining a first fluid path. A cover is coupled to the housing and permits access to the surgical access device. The housing is configured to receive the tube and the baffling discs, and the baffling discs are spaced apart from the first and second housing halves defining a second gap therebetween for defining a second fluid path. The first and second gaps form fluid convection channels for guiding fluid flowing in a proximal direction back into itself.

Abstract: A purse string suture instrument includes an end effector with first and second jaws disposed at a distal portion of an elongate tubular shaft. The first and second jaws are pivotably coupled to each other and to the elongate tubular shaft. The first and second jaws are spaced apart and define a gap therebetween. First and second pluralities of teeth extend perpendicularly from the first and second jaws respectively, and the first plurality of teeth is longitudinally offset from the second plurality of teeth. The first and second jaws are transitionable between open and approximated configurations. The approximated configuration is adapted to clamp tissue in the gap between the first and second jaws, thereby displacing sections of tissue outwardly between the first and second pluralities of teeth.

Abstract: An obturator includes an elongate shaft with proximal and distal portions. A button is located in the proximal portion of the elongate shaft. A cable has first and second wires and extends from the proximal portion of the elongate shaft and is attachable to a source of electrical energy. A plate is positioned in the distal portion of the elongate shaft and is coupled to the first wire. An electrode is located in the distal portion of the elongate shaft and is coupled to the second wire. An insulator is disposed in the distal portion of the elongate shaft and electrically isolates the plate from the electrode. The obturator is capable of tunneling through body tissue.

Abstract: A surgical access assembly includes an instrument valve housing defining a cavity, and a seal assembly disposed within the cavity of the instrument valve housing. The seal assembly includes a flange seal member and a centering mechanism. The flange seal member includes an annular member, a flange portion extending from the annular member, and a seal portion supported by the annular member and defining an opening dimensioned to receive a surgical instrument in a sealing relation. The flange portion includes first and second arcuate portions adjustably engaging the instrument valve housing in a sealing relation. The first and second arcuate portions have a parabolic profile. The centering mechanism maintains the seal assembly centered within the cavity of the instrument valve housing.

Abstract: In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.

Abstract: A ligation clip includes first and second beams that are movable in relation to each other from an open position to a clamped position to define an opening that is dimensioned to be received about end portions of vessel portions to be joined together during an anastomosis procedure to secure the end portions to an anvil shaft and/or an anvil retainer of a circular stapling device. The use of ligation clips to perform this function obviates the need to form a purse suture in the end portions of the vessel portions during the anastomosis procedure and reduces the amount of time required to perform an anastomosis procedure.
