摘要:
A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a cartridge when in an open position. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a matrix including glue beads suspended in the matrix. The staples are driven through the matrix to secure the matrix to tissue. The glue beads are activated when the matrix is secured to the tissue, such that the activated adhesive further secures the staple line in the tissue.

A surgical instrument includes an end effector and a staple cartridge that is insertable into the end effector. The staple cartridge includes a buttress material that is selectively coupled to the staple cartridge. In some versions the buttress material may be stapled to the staple cartridge by one or more attachment staples. Such attachment staples may be inserted into staple apertures formed through an upper deck of the staple cartridge. The attachment staples may include resiliently biased legs to frictionally resist removal. In some versions the attachment staples may be sized to form an interference fit in the staple apertures. Alternatively, the attachment staples may include barbs. A staple driver may be used to decouple the attachment staples. The staple driver may include staple forming pockets to bend the legs of the attachment staple when decoupling the attachment staple.
摘要:
A method for identifying molecules which mimic an idiotype of an autoimmune disease-associated auto-antibody (autoantibodies). The method comprises the following steps: (a) purifying autoantibodies from sera of one or more patients afflicted with the autoimmune disease; (b) binding the autoantibodies to a solid phase to form an affinity matrix; (c) contacting pooled plasma or B cells comprising immunoglobulins with the affinity matrix followed by removal of unbound plasma components; (d) eluting bound immunoglobulins, being anti-Idiotypic antibodies (anti-Id) to autoantibodies, from the matrix; (e) providing a molecular library comprising a plurality of molecule members; and (e) contacting the anti-Id with the molecular library and isolating those bound molecules which are bound by the anti-Id, the bound molecules being molecules which mimic an idiotype of autoantibodies. Also disclosed are such molecules.
