    摘要: 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.

    摘要: 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.
