Abstract:
1. A reinforcement device for use with a circular stapler that is adapted to create and seal a surgical opening in a patient comprising: a buttress material adapted for mounting on the circular stapler, the stapler having an anvil that is larger in diameter than the surgical opening that is created by the stapler, wherein following stapling with the stapler, the buttress material reinforces the surgical opening created by the stapler in the patient; the buttress material comprising a central region and a surrounding region and wherein the density of the material in the central region is higher than the density of the material in the surrounding region, wherein following stapling with the stapler at least a portion of the central region of the buttress material is configured to be severed from the surrounding buttress material to form at least one adaptive circular opening which corresponds to the surgical opening in the patient which is configured to be smaller in diameter than the anvil, and wherein following stapling with the stapler the adaptive opening in the surrounding buttress material is configured to allow the anvil to be removed therethrough without causing permanent alteration to the surrounding buttress material.
