  • Patent number: 6517554
    Abstract: A triceps for anastomosis, the triceps having two outer legs on opposing sides of a middle leg. A latch is located on one outer leg and the middle leg to hold the respective legs in a clamped position. An alignment post extends through the middle leg and cooperates with holes in the outer legs to allow the post to enter the holes and ensure alignment of the legs in use. The post has an enlarged base portion that does not pass through the hole and thereby limits movement of the outer legs relative to the inner legs and thereby limits clamping pressure at the free ends of the legs. The free ends of the legs have various cooperating shapes to facilitate everting and aligning tubular vessels and body tissue for anastomosis.

  • Publication number: 20020095166
    Abstract: A method for tensioning incisions made in a target vessel during an anastomosis procedure is provided. After an incision is made in a target vessel, incision tensioners are placed within the incision in order to tension the incision. The incision is tensioned when the incision tensioners are pulled taut in order to stretch the incision to a predetermined length or a predetermined force. The tensioners allow for proper grafting of a graft vessel to the target vessel in an end to side anastomosis. In addition, the incision tensioners allow the incision to have a known geometry, thereby allowing precise grafting of the graft vessel to the target vessel during the anastomosis procedure. After the incision is tensioned, the graft vessel is grafted to the target vessel using clips, sutures, staples or other anastomosis devices. One example of anastomosis clips are configured to capture the graft vessel and the target vessel such that the graft vessel grafts with the target vessel.

  • Patent number: 5893855
    Abstract: An improved surgical stapler for closing wounds, having an approximation device connected to a side of the surgical stapler. The approximation device is a hook positioned adjacent the stapled ejection port and is adapted to grip one side of a wound and enable the operator to temporarily close the wound, while precisely positioning the staple ejection port over the closed wound. Subsequent actuation of the stapler causes the wound to be precisely stapled closed. In an alternative embodiment, the approximation device is integrally formed from one leg of a surgical staple, and provides an asymmetric staple configuration. The longer staple leg is designed with a hook end. When the stapler is partially actuated, the staple legs partially protrude from the staple ejection port, and the longer staple leg can engage the skin on one side of a wound, and enable the temporary closing of the wound for accurate positioning.
