  • 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.

  • Patent number: 11166725
    Abstract: A surgical system and related methods includes a buttress applier cartridge, a first buttress assembly, and a second buttress assembly. The buttress applier cartridge has a housing and a platform. The first and second buttress assemblies respectively includes first and second buttresses and first and second adhesive layers thereon. The first adhesive layer is parallel to the first buttress and defines a first adhesive pattern having a first outer adhesive profile. The second adhesive layer is parallel to the second buttress and defines a second adhesive pattern having a second outer adhesive profile. The exposed second outer adhesive profile in the transverse direction is the same as the exposed first outer adhesive profile in an opposite transverse direction such that the first and second buttress assemblies are interchangeable with the first and second portions of the end effector of the surgical instrument.

  • Patent number: 11103243
    Abstract: A buttress applier cartridge assembly includes buttress assemblies and a buttress applier cartridge for use with an end effector of a surgical stapler. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The buttress applier cartridge includes a housing and a platform that extends longitudinally and supports the buttress assemblies. The buttress applier cartridge further includes a predefined pocket in the platform between each buttress assembly that allows a curved tip of the end effector to pass through. The platform is thinner along a central axis and becomes progressively thicker in the lateral direction. In some examples the predefined pocket is a slit in the platform.

  • Patent number: 11033269
    Abstract: A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

  • Patent number: 10905424
    Abstract: A buttress applier cartridge assembly includes buttress assemblies and a buttress applier cartridge for use with an end effector of a surgical stapler. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The buttress applier cartridge includes a housing, a platform that extends longitudinally and supports the buttress assemblies, and an opening to accommodate a curved tip of the end effector when clamping the end effector onto the platform to transfer the buttress assemblies to the end effector. A proximal alignment feature of the buttress applier cartridge contacts the end effector to align the end effector with the buttress assemblies prior to attaching the buttress assemblies to the end effector.
