  • Adhesive distribution on buttress for surgical stapler
    Patent number: 11166724
    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.

  • SURGICAL STAPLER BUTTRESS WITH TISSUE IN-GROWTH PROMOTION
    Publication number: 20200205822
    Abstract: A buttress assembly for use with a surgical stapled site has a buttress and an adhesive on one side of the buttress. The buttress itself has a multi-layer construction with a mesh layer on one side, a film layer on the other side, and an adhesive film layer in between the mesh layer and film layer. The mesh layer is a knit material with multiple openings that provide space for and promote tissue ingrowth with the buttress. As such the buttress is oriented in use so that the mesh layer faces and contact the tissue at the surgically stapled site. Opposite to the mesh layer, the film layer faces away from the tissue at the surgically stapled site and acts as an adhesion barrier.
