An apparatus for supporting tissue during compression prior to the insertion of a surgical element into the tissue has a substrate. The substrate is made from a predetermined material. The predetermined material has a thickness and a predetermined stress strain profile. The predetermined stress strain profile is complementary to a stress strain profile of the tissue and permits the substrate to support the tissue when the surgical element is delivered into the tissue. The substrate provides hemostasis control of the tissue when the surgical element is delivered into the tissue.

Mechanically tuned buttress material to assist with proper formation of surgical element in diseased tissue

Systems of releasably connecting staple line buttress material to the jaws of a surgical stapling instrument are provided. The systems include retainers configured to engage the buttress material and releasably retain the buttress material on the jaws of the surgical stapling instrument prior to stapling tissue. In certain embodiments, the retainers remain with the jaws of the instrument after stapling of tissue. In alternative embodiments, the retainers remain with the buttress material after being stapled to tissue.

Detachable buttress material retention systems for use with a surgical stapling device

Multilayer structures including a porous layer and a non-porous layer are useful as buttresses when associated with a surgical stapling apparatus.

Buttress and surgical stapling apparatus

A surgical stapler is provided having a pair of jaws including a staple containing cartridge and an anvil. Buttress material is releasable affixed to the staple containing cartridge and the anvil. One of the jaws includes a pair of longitudinal projections at a first end of the jaw and configured to frictionally engage corresponding slots in a first end the buttress material. One of the jaws includes a post at a second end of the jaw. The buttress material includes a hole in a second end of the buttress material for receipt of the post.

Interlocking buttress material retention system

A stabilizer is provided to secure and fix the position of a cannula assembly relative to tissue. The stabilizer is a liquid swellable member which expands within an incision in tissue in response to the absorption of a liquid. The stabilizer includes an inner adhesive layer to secure the stabilizer relative to a cannula assembly. The stabilizer is formed of a polymeric gel or foam. In one embodiment, the stabilizer is fixedly secured to an elongate tubular member of a cannula assembly. In an alternative embodiment, the stabilizer is mounted for longitudinal movement along an elongate tubular member of a cannula assembly.
