An adapter seal is provided which is adapted to be mounted to a cannula assembly. The adapter seal preferably defines a channel which is adapted to cooperate with walls extending upward from a cannula housing. In a second embodiment, a button is provided that may be repositioned such that its aperture aligns with an aperture formed in the body member of the adapter seal. The button is preferably joined to the body member by a flexible strap.

A method for forming a surgical clip and fixture for use therein includes molding a polymeric clip body, the clip body having hinged legs, the polymer of the clip body being substantially amorphous. The clip body can then be moved to a desired configuration while being subjected to a temperature above the glass transition temperature. The molded clip body is then heated to a temperature within the crystallization range for a period of time sufficient to impart at least 20% crystallinity thereto to impart a spring back property. Also disclosed herein is a fixture for forming a surgical clip in accordance with this method.

Forming latchless surgical clip and fixture for use therein

An accessory device for dissipating electrical energy from a surgical device is provided. The electrical energy is induced on the surgical device when a charge-inducing instrument, e.g. an unipolar electrocautery device, is energized in proximity thereto. The induced energy is dissipated by conveying the energy along an electrically conductive coating adhered to a housing of the device to an energy dissipation region.

Energy dissipation device

A latchless surgical clip provides effective hemostasis while avoiding or minimizing the risk of injury to the tissue site to which the clip is applied. The clip includes a hinge region having an elastic spring back property so that the legs are spread apart to engage opposing sides of the tissue and then released to return to their tissue clamping (closed) position. A method for forming the latchless surgical clip and a fixture for use therein are also described.
