Abstract: An endoscopic surgical instrument has a distal end configured to perform an action on tissue; a proximal end; a beam; a drive rod; and at least one rail supporting at least one bearing, the at least one bearing movable relative to the at least one rail. The distal end of the instrument is configured to receive at least a portion of the beam, the beam movable longitudinally in response to an action on the drive rod. The at least one rail is shaped and configured to contact the beam tangentially to prevent the beam from buckling as the beam is moved longitudinally.

Abstract: A surgical staple, stapler, and related methods are disclosed. A surgical staple has a pair of staple legs and a backspan positioned between the pair of staple legs, the backspan and the pair of staple legs formed by bending a wire. At least one recess is positioned in the wire to influence a folding direction of at least one staple leg during tissue stapling. The surgical staple is configured to pierce tissue only once with each staple leg during the tissue stapling.

Abstract: A surgical stapler and related components and methods are disclosed. The stapler has an anvil having a staple pocket, and a cartridge. The cartridge supports a staple pusher and a B-form staple, the B-form staple having a backspan, a proximal leg, and a distal leg, the backspan having a proximal portion coupled to the proximal leg, a distal portion coupled to the distal leg, and a central portion therebetween. The surgical stapler is configured to cold work at least a portion of the backspan during a deployment of the surgical staple.

Abstract: A device for use in laparoscopic surgery is provided. The device has a sheath, a surgical action mechanism configured to deliver an action and to limit the device to a single use, at least one telescoping section configured to structurally support the surgical action mechanism, a first spacer, and a second spacer. The surgical action mechanism, the telescoping section, the first spacer, and the second spacer are configured to move within the sheath from a pre-action configuration, to an action configuration, and to a return configuration.
