  • Patent number: 8789736
    Abstract: A stapling element is provided, operative to pierce and penetrate a tissue by a first end, and close around the tissue. Three factors help prevent local necrosis: 1. The self-closing feature of the staple does not lead to tissue crushing. 2. Edge seams are applied generally perpendicular to the tissue edge, allowing for blood supply to the tissue edge. 3. Excess tissue is cut off at the seam, minimizing the amount of tissue that may undergo local necrosis. A physical feature prevents the staple from rotating, when in an application shaft, to maintain a predetermined closing direction. The stapling element may be formed of an alloy, a pure metal, a polymer, or a composite of at least two materials. Additionally, staplers, anastomosis devices, and methods for their applications are described.

  • Patent number: 5520701
    Abstract: In order to destroy vascular deformations in the human body, a clamp is provided which is made from titanium. The clamp is expanded in the relieved state and is transferable into the clamping position by a clamping ring, which is displaceable along the clamp in the attached state. The clamp is introduced into the body by a probe, which has a tubular casing and a positioning bar guided therein. The clamp is transferred into the region of the deformation and applied at the application location as a result of the clamping ring being transferred into the clamping position. The transfer is caused by a relative movement between tubular casing and positioning bar. The probe is then released from the positioned clamp.
