Abstract: A method is provided for applying an adjunct element to a surgical stapler end effector having first and second stapling surfaces using an applicator. The method includes providing the end effector in an open state in which the first and second stapling surfaces are spaced apart. With the end effector in the open state, at least a portion of the applicator is positioned between the first and second stapling surfaces. Without engaging a closure system input feature of the surgical stapler, a portion of the end effector is compressively engaged by the applicator to thereby secure the adjunct element to one of the first or second stapling surfaces. The applicator and the end effector are withdrawn relatively away from one another so that the adjunct element remains attached to the one of the first or second stapling surfaces of the end effector.

Abstract: An assembly includes an applicator, which includes a housing defining a gap configured to receive an end effector jaw of a surgical stapler. The applicator also includes a platform positioned within the gap. The assembly also includes a buttress assembly having a first length and positioned on the platform. The assembly further includes a trimming feature presented by the applicator or the buttress assembly, and configured to facilitate trimming of the buttress assembly from the first length to a predetermined second length.

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.

Abstract: Retainers and retainer systems for staple cartridges with implantable adjuncts are disclosed. The retainers and retainer systems enable a compressive force to be applied to implantable adjuncts on staple cartridges.

Abstract: The disclosed technology includes a surgical adjunct that includes bioabsorbable material such as a polyurethane foam. A volumetric ratio of the polyurethane foam to the total volume of the surgical adjunct may be in a range of about 0.125 to about 0.325. A glass transition temperature of the surgical adjunct may be about 0° C. to about 40° C.

Abstract: Compressible adjuncts for use with a surgical cartridge are provided. In one exemplary embodiment, a compressible adjunct includes a biocompatible adjunct material that is configured to be releasably retained on a staple cartridge and that is configured to be delivered to tissue by deployment of staples in the cartridge. The adjunct material includes a lattice main structure having at least one absorbable sub-structure formed in the lattice main structure, the at least one absorbable sub-structure configured to control fluid movement through the adjunct material such that the fluid movement impacts healing of tissue adjacent the adjunct material when the adjunct material is in a tissue deployed state. Stapling assemblies for use with a surgical stapler are also provided.

Abstract: An apparatus includes a body with a first body portion, a second body portion opposed from the first body portion, and a connecting portion that couples a proximal end of the first body portion with a proximal end of the second body portion. The connecting portion is configured to permit the first and second body portions to move toward and away from one another between a plurality of angular orientations. The first and second body portions define a distally opening angle. A first adjunct element and a second adjunct element are disposed on outwardly facing surfaces of the first and second body portions. The first and second body portions may be fixed in each of the angular orientations and may simultaneously apply the first and second adjunct elements to first and second jaws, respectively, of a surgical stapler end effector.
