摘要： A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.

摘要： Apparatus and methods for interlocking stent segments which provide for a secure engagement between the expanded stent segments are described herein. Stent segments which are able to slide freely relative to one another along the deployment catheter prior to expansion may be secured to one another when expanded and/or deployed into the vessel. Securement upon expansion of the stent segments may be accomplished, in part, by utilizing one or more coupling mechanisms between adjacent stent segments which securely interlock the segments to one another by taking advantage of the changing geometry of the stents during expansion.

In one embodiment, a stent delivery system (100) includes a catheter (15) comprising a catheter body having a distal end, a proximal end, a longitudinal axis (200) and a lumen. An expansion device, which in one embodiment is a balloon (20), is disposed near the catheter body distal end, and a stent (10) having a side hole (12) is disposed over the expansion device. An ultrasound transducer (22) is disposed near the catheter body distal end and positioned for transmitting and receiving ultrasound signals through the side hole to help properly align the stent side hole with a branch vessel (16).

摘要： A bi-directional stent delivery system includes an inner elongate shaft, a radially expandable prosthesis disposed over the inner elongate shaft, an outer elongate shaft, and a shuttle sheath disposed over the radially expandable prosthesis. The distal portion of the inner shaft is releasably coupled to the distal portion of the shuttle sheath, and the distal portion of the outer shaft is releasably coupled the proximal portion of the shuttle sheath. Distal advancement of the inner shaft advances the shuttle sheath distally when the outer shaft is uncoupled from the shuttle sheath, thereby allowing the prosthesis to radially expand from a proximal end to a distal end. Proximal retraction of the outer shaft retracts the shuttle sheath proximally when the inner shaft is uncoupled from the shuttle sheath, thereby allowing the prosthesis to radially expand from a distal end to a proximal end thereof.
摘要翻译：双向支架输送系统包括内细长轴，设置在内细长轴上的可径向扩张的假体，外细长轴和设置在可径向扩张的假体上的梭鞘。内轴的远端部分可释放地联接到穿梭护套的远端部分，并且外轴的远端部分可释放地联接在穿梭护套的近端部分上。当外轴与穿梭护套脱离联接时，内轴的远端前进使梭梭远向前进，从而允许假体从近端向远端径向膨胀。当内轴与穿梭护套脱离联接时，外轴的近端缩回使穿梭护套向近侧缩回，从而允许假体从远端到其近端径向膨胀。
