    摘要： An apparatus includes a housing a platform, and a first buttress assembly. The housing defines a gap configured to receive a portion of an end effector of a surgical stapler. The housing includes proximal and distal portions. A portion of the platform is exposed within the gap defined by the housing. The platform includes proximal and distal portions. The first buttress assembly is positioned on at least the proximal portion of the platform. The first buttress assembly is exposed in the gap defined by the housing. At least one of the distal portion of the platform or the distal portion of the housing includes a cavity configured to receive a curved distal tip of the end effector.

    摘要： Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

    摘要： A surgical staple including at least two deformable members which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable members can include a non-circular cross-section which can dictate the direction and manner in which the deformable members are bent. In at least one embodiment, the non-circular cross-section can include a flat portion which can cause the deformable members to bend in the direction of the flat portion. In various embodiments, the at least two deformable members can be connected by a dissolvable or bioabsorbable crown. In at least one various embodiment, the crown can dissolve and can, depending on the cross-sectional geometry of the deformable members, reduce the force or pressure applied to soft tissue captured within the staple by the bent deformable member.
