摘要： There is disclosed a method of stent placement which comprises first guiding a guidewire through the vasculature. Second, a balloon catheter which contains two guidewire lumens is strung along the guidewire into position at the bifurcation. The distal opening of the second guidewire lumen abuts the proximal end of the bifurcation. Thereafter, a second guidewire is strung through the first balloon catheter and out the distal opening of the second guidewire lumen. Thus, resident in the second bifurcation leg is the second guidewire. Then, a second standard stent delivery balloon catheter is guided along the second guidewire to a position within the bifurcation. Typically, expansion of both stents can be done one right after the other after proper placement of the first and second balloons.

摘要： A helical stent having flat ends for insertion into a vessel of a patient provides a safe and effective means for ensuring the patency of the vessel. The stent comprises a tubular member having a thickness, front and back open ends, and a longitudinal axis extending therebetween. The tubular member includes a plurality of helically oriented continuous adjacent hoops extending between the front and back ends. The hoops have a plurality of longitudinal struts, each having opposing ends and a center therebetween, wherein the ends of the struts are shaped to form a plurality of loops connecting adjacent struts at the ends of the struts. The tubular member has end loops and the front and back ends thereof, wherein the end loops at each end are substantially aligned with each other along a plane substantially perpendicular to the longitudinal axis.

摘要： The present invention relates to a medical device, and in particular, to a stent-based valve. The valve includes a radially expandable structural frame including an anchor structure having a first and a second open end, a connecting member having a first and a second end, and a cantilever valve strut having a first and a second end. The first end of the connecting member is attached to the second end of the anchor structure. The first end of the cantilever valve strut is cooperatively associated with the second end of the connecting member. The prosthetic valve further includes a biocompatible membrane assembly having a substantially tubular configuration about the longitudinal axis, with a first open and a second closed end. The first end of the membrane assembly is attached to the structural frame along the second end of the cantilever valve strut.
