  • Publication number: 20200205820
    Abstract: A buttress assembly for use with a surgical stapled site has a buttress and an adhesive on one side of the buttress. The adhesive on the buttress is applied in a pattern where the adhesive extends near or along the edges of the buttress while a center region of the buttress remains relatively free of adhesive. The adhesive is applied such that it extends continuously along the buttress and has a height such that the adhesive creates a sealing attachment with an end effector. The adhesive can be applied in an uneven distribution such that there is more adhesive applied at one end of the buttress than the other. The adhesive can also be applied in a symmetric or asymmetric distribution about a longitudinal axis of the buttress.

  • Publication number: 20200205823
    Abstract: A buttress applier cartridge assembly includes a buttress assembly and a buttress applier cartridge. The buttress assembly includes a buttress configured to support a staple formed therein as well an adhesive layer for adhering to an end effector. The buttress applier cartridge includes a housing defining a gap extending in a longitudinal direction as well as a platform. The platform extends longitudinally from a proximal portion to a distal portion and is exposed in a transverse direction adjacent to the gap. The proximal and distal portions respectively have a proximal stiffness and a different, distal stiffness in the transverse direction. Thereby, the proximal and distal portions support the buttress assembly thereon to deform with the proximal and distal stiffnesses and provide reactionary forces of at least the predetermined minimum force while receiving the end effector for accommodating various camber orientations of the end effector.
