    摘要： The present invention provides, in a first aspect a bifurcated stent for use in juxtaposition with an angelogical bifurcation. The bifurcated stent comprises a proximal portion adapted to be disposed within a blood vessel in juxtaposition with a bifurcation, a first distal stent portion adapted to extend across the bifurcation into one of the branched blood vessels, and a second distal stent portion adapted to allow blood to flow from the proximal portion into the other branch blood vessel. The invention also embraces a bifurcated prosthesis including such a bifurcated stent and a tubular graft layer formed from a biocompatible fabric in juxtaposition with the stent. In a second aspect of the invention there is provided a stent connection for joining two stents one to the other to define a continuous lumen through the two stents. Said stent connection comprises a first stent including a male engaging portion which can be compressed radially inwardly and a second stent including a female cooperating portion. Said male engaging portion can be entered into the female cooperating portion in a radially compressed state and thereafter caused or allowed to expand in the female cooperating portion to join the two stents together.

    摘要： Methods for restoring blood flow in occluded blood vessels are disclosed. The methods can include accessing an artery with a catheter system and locating an occluded zone within the artery caused by an embolus. The catheter system can include a microcatheter and a blood flow restoration device or an embolus removal device having a self-expandable member configured to be delivered through the microcatheter in a compressed configuration and to be deployed to an expanded configuration upon retraction of the microcatheter. The methods can include deploying the self-expandable member at the location of the occluded zone such that the self-expandable member engages and captures the embolus upon deployment of the self-expandable member and removing the embolus by withdrawing the blood flow restoration device or the embolus removal device.

    摘要： Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can comprise a three-step progressive treatment process that includes immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis and maceration. The progressive, or modular, treatment can be provided by a system or kit of one or more treatment devices.

    摘要： Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.
