    摘要: A staple having a crown and first and second deformable members extending from the crown. In at least one embodiment, the staple further includes a base connecting the first and second deformable members where the base is not entirely co-planar with the first and second deformable members. In these embodiments, the crown can be overmolded onto, or attached to, the base and provide a larger and/or more stable tissue-contacting surface for supporting the tissue captured by the staple. As a result, the possibility of the staple being pulled through the tissue and/or the tissue tearing within or around the staple is reduced.

    摘要: Various methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided and includes an elongate member having a proximal support member configured to rest against an external tissue surface, a flexible elongate central portion extending distally from the proximal support member and configured to extend through tissue, and an inflatable distal portion coupled to a distal end of the central portion. The distal portion is movable between an initial configuration, in which the distal portion is configured to be passed through an incision in tissue, and an inflated configuration in which the distal portion is expanded such that the central portion forms a working channel through the tissue for access to a body cavity. The distal portion can include an opening such that gas delivered to the distal portion can flow through the opening to insufflate a body cavity.
