Abstract

This patent application is for the design of a vascular occluding bridged self-expanding metal stent (VOBSEMS) for fixed and immobile selective vascular occlusion and thrombosis of arteries and veins. Current vascular self-expanding metal stents (SEMS) are designed to open atherosclerotic arteries such as coronary arteries. Once deployed the SEMS remains immobile and permanent across the stenosis of the artery. In contradistinction to the SEMS which opens occluded stenotic arteries, the VOBSEMS is used to occlude and clot arterial and venous blood flow. The VOBSEMS clots blood vessels with unique metal bridges located inside the stent. The unique metal bridges are made of platinol a memory metal alloy identical to the stent, but imbedded with dacron fibers to promote clotting. The bridges are positioned inside of the VOBSEMS and secured to the stent by bridge end loop design. The bridges are staggered and rotated inside the stent with a spiral staircase appearance. The wire bridge is straight in the deployed or unsheathed position and acute angle in the undeployed or sheathed position. Therefore blood clots inside the VOBSEMS as blood flowing through a VOBSEMS encounters staggered …
