    摘要： The present invention is directed to a stent for use in a bifurcated body lumen having a main branch and a side branch. The stent comprises a radially expandable generally tubular stent body having proximal and distal opposing ends with a body wall having a surface extending therebetween. The surface has a geometrical configuration defining a first pattern, and the first pattern has first pattern struts and connectors arranged in a predetermined configuration. The stent also comprises a branch portion comprised of a second pattern, wherein the branch portion is at least partially detachable from the stent body.

    摘要： Embodiments are described for closing vascular access ports, such as arteriotomies, which involve placement and deployment of an expandable device configured to prevent blood flow across a subject arteriotomy while also keeping disturbance of intravascular flow to a minimum. Suitable prostheses may comprise one or more frames constructed from lengths of flexible materials, such as shape memory alloys or polymers. Such frames may be coupled to sheetlike or tube-like structures configured to spread loads, minimize thrombosis which may be related to intravascular flow, and maintain hemostasis.

    摘要： The present invention provides a catheter system which includes a catheter, an expandable balloon, at least one securement member, and a stent. The stent is disposed about the catheter and comprises at least one undulating band that extends circumferentially around the longitudinal axis of the catheter system. The undulating band includes interconnected strut members which form a series of alternating peaks and valleys. Adjacent strut members comprise a strut pair, wherein each strut member of the strut pair includes a protuberance positioned along the length of the strut member, between a peak and a valley. The protuberances, which are substantially circumferentially opposed to one another, engage a securement member, thereby minimizing lateral stent movement on the delivery system during delivery.
