Abstract
Implantable adjuncts for use with a surgical instrument are disclosed. The implantable adjunct includes a first mesh positioned about a first side of the longitudinal knife slot and a second mesh positioned about a second side of the longitudinal knife slot such that the first and second meshes define a gap substantially aligned with the longitudinal knife slot of the staple cartridge body.
Claims19
An implantable adjunct for use with a surgical instrument, the implantable adjunct comprising:
- a longitudinal knife slot along a longitudinal axis of the implantable adjunct;
- a first mesh positioned about a first side of the longitudinal knife slot;
- and
- a second mesh positioned about a second side of the longitudinal knife slot,
- wherein the first mesh and the second mesh comprise a plurality of first fibers that form a three-dimensional structure and comprise a first material;
- wherein the first mesh and the second mesh define a gap substantially aligned with a longitudinal knife slot of a staple cartridge body, and
- wherein the first and second meshes comprise:
- a medial portion proximal to the longitudinal knife slot and a lateral portion proximal to a lateral side of the respective mesh, and the medial portion comprises a higher density of first fibers relative to the density of first fibers in the lateral portion.
An implantable adjunct for use with a surgical instrument, the implantable adjunct comprising:
- a longitudinal knife slot along a longitudinal axis of the implantable adjunct;
- a first mesh positioned about a first side of the longitudinal knife slot;
- and
- a second mesh positioned about a second side of the longitudinal knife slot, wherein the first mesh and the second mesh comprise a plurality of first fibers comprising a first material and a plurality of second fibers comprising a second material, the second material different than the first material, and wherein the first and second meshes comprise:
- a medial portion proximal to the longitudinal knife slot and a lateral portion proximal to a lateral side of the respective mesh, and the medial portion comprises a higher density of the fibers than the density of the respective fibers in the lateral portion.
