20100072254SURGICAL STAPLING APPARATUS - A loading unit for use with a surgical stapling apparatus is provided and includes a tool assembly having a cartridge assembly and an anvil assembly that are movable in relation to one another; a surgical buttress releasably secured to a tissue contacting surface of the anvil assembly and/or the cartridge assembly, wherein each surgical buttress is secured to the anvil assembly and/or the cartridge assembly by at least one anchor; a release assembly associated with the anvil assembly and/or the cartridge assembly; and a drive assembly slidably translatable through the tool assembly between proximal and distal positions, wherein the drive assembly actuates the release assembly to thereby release the anchor to free the surgical buttress from the anvil assembly and/or the cartridge assembly.03-25-2010
20100147921Surgical Apparatus Including Surgical Buttress - A surgical buttress includes a body portion and a band disposed on each of the distal and proximal ends thereof. The surgical buttress is configured to attach to an end effector of a surgical stapling apparatus. The body portion, having perforations disposed thereon, overlies the working surface of one of the first or second jaws of the end effector. A resilient portion extends transversely beyond the side edges of the first or second jaws. Each band remains attached to the end effector following the firing thereof. The proximal band is removably attachable to a hook feature disposed on one of the first or second jaws of the end effector. The surgical buttress can be made from suitable degradable or non-degradable materials. One embodiment contemplates a detachable and disposable single use loading unit. A method of attaching the surgical buttress to a surgical apparatus is also envisioned.06-17-2010

20100243711Center Cinch And Release Of Buttress Material - A buttressed anvil assembly is provided for use with a surgical stapling instrument. The buttressed anvil assembly generally includes an anvil member having a strip of buttress material attached thereto by a pair of sutures. A tensioning mechanism is provided to secure or tension the buttress material to the anvil member prior to use and allow for release of the buttress material after stapling of tissue. The tensioning mechanism includes a cinch track engageable with one of the pair of sutures.09-30-2010
20100249805Crimp And Release Of Suture Holding Buttress Material - A mechanism is provided for crimping and releasing a suture securing a strip of buttress material to an end effector. The mechanism includes a retention member movably mounted within the end effector. The retention member is movable from a first position crimping the suture to the end effector to a second position releasing the suture from the end effector. The mechanism additionally includes a follower member, engageable with the retention member, and movable in response to actuation of a surgical instrument to move the retention member between the first and second positions. A lock mechanism is also provided to secure the retention member in the first position. The follower member operates to disengage the lock mechanism.09-30-2010
20100282816Stapler Cartridge and Channel Interlock - A surgical stapling device including a handle assembly, an endoscopic portion and an end effector is disclosed. The endoscopic portion extends distally from the handle assembly and defines a first longitudinal axis. The end effector defines a second longitudinal axis and includes an anvil assembly and a cartridge assembly. The end effector includes a cartridge channel configured and dimensioned to securely receive a cartridge therein.11-11-2010
20110084114Pair of Double Staple Pusher in Triple Row Stapler - A staple cartridge includes outer and inner rows of retention slots that are adapted and configured to retain staples. The staple cartridge further includes a staple pusher including a plurality of pusher plates. A staple pusher includes pusher plates that are laterally spaced apart to engage staples within the outer rows of at least three rows of retention slots.04-14-2011
