Abstract: A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a trocar mechanism that includes a trocar member that is at least one of rotatable or articulable relative to a housing of the trocar assembly.

Abstract: Embodiments of the present invention provide an improved vascular occlusion device for occlusion of a passageway, cavity, or the like. According to one embodiment, a medical device for occluding a left atrial appendage is provided. The medical device includes a first portion having at least one plane of occlusion that is configured to be positioned outside of the left atrial appendage, and a second portion having at least one plane of occlusion that is configured to be at least partially positioned within a cavity defined by the left atrial appendage.

Abstract: A device for furling a tissue specimen retrieval bag includes a housing supporting a spindle assembly therein, the spindle assembly including a drive shaft having a proximal end, a distal end, and a gear disposed therebetween. An activation switch is pivotably coupled to the housing and is configured for selective, operable engagement with the gear. The activation switch is selectively positionable relative to the gear between a first position wherein the gear and drive shaft are locked from rotation in a first direction and a second position wherein the gear and drive shaft are free to rotate in the first direction. An elongated shaft is operably coupled to the distal end of the drive shaft and is configured for rotation therewith. A biasing element is configured to provide a rotational load to the drive shaft.

Abstract: A surgical instrument and method of manipulating colon tissue of a patient includes a body having a firing mechanism, a shaft assembly, and an end effector operatively connected to the firing mechanism via the shaft assembly. The end effector is configured to receive a cartridge selectively actuated by the selective manipulation of the firing mechanism. A distal end portion of the end effector includes a first end, a second end laterally opposite the first end, and a distal crest laterally positioned between the first and second ends that projects distally beyond the first and second ends. The distal end portion also includes an arcuate distal surface extending along the distal with a radius of curvature configured to be received against the pelvic bowl of the patient to position the end effector relative to colon tissue for manipulating the colon tissue with the cartridge.
