Circular stapler buttress combination

A kit for use in a circular stapling procedure employing a circular stapler instrument that comprises a staple cartridge component having a central recessed aperture and a corresponding anvil component having a central recessed aperture,

• the kit comprising one or more generally circular portions of buttress material adapted to be a) stably positioned upon the staple cartridge and/or anvil components of the stapler instrument prior to, or at the time of, use, b) while in position upon the stapler component(s), to then be delivered to a tissue site in combination with the stapler components, c) upon delivery of the components and positioned material portion(s) to the tissue site, to provide a first region of buttress material as a staple line buttress seal between joined tissue sections upon activation of the stapler, and optionally, d) to permit the removal of one or more portions of the second region of the buttress material upon activation of a stapler knife provided by the stapler, wherein the buttress material portion adapted to fit the cartridge component comprises a circumferential disc having an integral raised center portion adapted to fit the central recessed aperture of the cartridge, and the buttress material portion adapted to fit the anvil component comprises a circumferential disc having an integral raised center portion adapted to fit the central recessed aperture of the anvil.

A combination medical device comprising:

• a) a circular stapler instrument, comprising a staple cartridge component and corresponding anvil component, and
• b) one or more portions of buttress material adapted to be a) stably positioned upon the staple cartridge and/or anvil components of the stapler instrument prior to, or at the time of, use, b) while in position upon the stapler instrument component(s), to then be delivered to a tissue site in combination with the stapler instrument components, c) upon delivery of the components and positioned material portion(s) to the tissue site, to provide a first region of buttress material as a staple line buttress seal between joined tissue sections upon activation of the stapler instrument, and optionally, d) to permit the removal of one or more portions of a second region of the buttress material upon activation of a stapler instrument knife provided by the stapler instrument,
• wherein at least one of the buttress material portions comprises two or more regions, including a first region adapted to serve as the staple line buttress itself, together with a second region adapted to assist in positioning and/or retaining the buttress material upon a stapler component, and wherein one or more portions of the second region are adapted to be removed from the tissue site upon formation of the staple seam and activation of a stapler knife, the second region being generally concentric to the first region, the first and second regions cooperating to provide a desired three dimensional and/or topographic structure adapted to position and/or retain the materials in place upon the respective stapler component.
