Abstract: Access assemblies include an instrument valve housing and a valve assembly disposed within the instrument valve housing. The valve assembly includes a guard assembly, and a seal assembly disposed adjacent the guard assembly. The seal assembly includes a plurality of seal segments defining a substantially hexagonal body. Each seal segment of the plurality of seal segments includes a base portion and a seal portion extending from the base portion. Each base portion including an outer edge formed of three segments. Each seal segment of the plurality of seal segments is disposed relative to an adjacent seal segment of the plurality of seal segments such that two of the three segments of the outer edge of the respective seal segments align with each other. The valve assembly also includes a centering mechanism for biasing the seal assembly and guard assembly towards a center of the cavity of the instrument valve.

Abstract: A surgical device includes gripping sleeves that can be secured to jaws of the surgical device to allow the device to function as a grasper. The gripping sleeves include nonslip surfaces which are brought into juxtaposed alignment with each other when the surgical device is moved from an open position to a clamped position to clamp tissue between the nonslip surfaces of the gripping sleeves.

Abstract: A surgical stapling device includes a channel member and a staple cartridge that is received within the channel member and is formed from a functional portion and a dummy portion that are coupled together. The functional portion of the staple cartridge defines a knife slot and a plurality of staple receiving pockets. Each of the staple receiving pockets supports a staple and a pusher that is movable within the respective staple receiving pocket to eject the staple from within the staple receiving pocket. The dummy portion of the staple cartridge defines a knife slot and is devoid of staples.

Abstract: A surgical access assembly includes a sleeve assembly, a base member, and a sealing assembly. The sleeve assembly includes a proximal ring, a distal ring, and a sleeve defining a passage therethrough. The base member includes an annular body including a coupling member. The annular body defines an opening in communication with the passage of the sleeve, and a circumferential groove configured to support the proximal ring of the sleeve assembly. The sealing assembly includes an annular frame and a seal dimensioned to cover the opening of the base member in a sealing relation. The coupling member of the base member releasably secures the sealing assembly to the base member. The annular frame of the sealing assembly is configured to be in registration with the annular body of the base member such that the proximal ring is interposed between the base member and the sealing assembly.

Abstract: A balloon trocar includes a housing and a cannula assembly. The housing includes an inflation port. The housing defines a cavity configured to receive a seal therein. The cannula assembly includes a tubular member extending from the housing, an inflatable balloon secured to the tubular member, and a pin. The tubular member defines a lumen, a fluid channel, and an actuation channel. The lumen is in communication with the cavity of the housing. The lumen is configured to receive a surgical instrument therethrough. The fluid channel provides fluid communication between the inflatable balloon and the inflation port. The actuation channel is configured to slidably receive the pin therein. The pin includes a tip configured to pierce the inflatable balloon to deflate the inflatable balloon.
