摘要： An apparatus for joining two hollow organ sections with an annular array of surgical staples includes a staple cartridge component, an anvil component, a buttress component and a fastening member. The staple cartridge component includes a plurality of surgical staples arranged in an annular array. The anvil component is movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp the organ sections between the staple cartridge and anvil components. The buttress components are configured and dimensioned to be positioned on a distal surface of the staple cartridge component and the proximal surface of the anvil component. In particular, the buttress component includes a buttress member and a plurality of circumferentially arranged tabs extending proximally from the buttress member. The fastening member is configured and dimensioned to engage the plurality of circumferentially arranged tabs to securely position the buttress component on the staple cartridge component.

摘要： A surgical stapling device for joining tissue portions includes a handle assembly, and a tubular body portion having a staple cartridge assembly containing a plurality of surgical staples in an annular array. The surgical stapling device includes an anvil assembly having a shaft for removably connecting the anvil assembly to the tubular body portion. The anvil assembly and the tubular body portion are juxtaposed with respect to one another along the shaft and are arranged so as to be approximated with respect to one another. The surgical stapling device includes a buttress material supported by the tubular body portion and disposed between the anvil assembly and the staple cartridge assembly. The surgical stapling device includes a suture material that is adapted for engagement with the tubular body portion and the buttress material to secure the buttress material to the tubular body portion.

摘要： Methods for making bioabsorbable copolymer filaments are provided herein. The methods include drying the polymer pellets to be extruded, melt extrusion of copolymer components, stretching the filaments in one or more draw steps and permitting the drawn filaments to relax. The copolymer preferably contains units derived from glycolide or glycolic acid and units derived from an alkylene carbonate, such as, for example, trimethylene carbonate.
