    摘要: Embodiments herein provide differential dilation stents for use in percutaneous interventions, such as transluminal bypass procedures. In some embodiments, the stents may be used in the process of creating an arteriovenous (AV) fistula during a percutaneous bypass procedure, and such stents may have two or more specialized regions that are configured to adopt a predetermined diameter, shape, and/or tensile strength upon insertion in order to suit the needs of the vessel or procedure. The disclosed stents may be used for creating and/or maintaining an arterial/venous fistula for bypass of an occlusion in a cardiac artery using a cardiac vein, or the femoral artery, for example using the tibial or popliteal vein.

    摘要: A low profile parenchymal bolt having a cap, a body, and a base with two rods located through the cap that the base. Levers are located at the cap and are interconnected with the rods. Moving the levers outwardly pulls the rods and base towards the cap compressing the body and causing its outer diameter to increase into contact with an opening in the skull of a patient to form a fluid-tight seal and fixing the bolt in position. A lumen permits mounting an instrument through the bolt and when the body is compressed, the lumen reduces in size thus clamping the instrument in place in the bolt and forming a fluid-tight seal. Through use of non-ferric materials, artifacts in MRI are reduced.
