    摘要: A self-expanding medical device delivery system includes a plurality of trigger wires. The trigger wires retain a self-expanding medical device by forming a bend about structural members located on the proximal portion of the medical device. The proximal portions of the trigger wires have a greater diameter than the distal portions of the trigger wires to provide increased bending strength. An operator releases the self-expanding medical device by withdrawing the trigger wires in the distal direction. In some embodiments, a small portion at the proximal end of each trigger wire has a smaller diameter than the rest of the proximal portion. In other embodiments, the proximal and distal portions of each trigger wire each have a greater diameter than the center of the trigger wire.

    摘要: The present embodiments provide a valve for implantation in a patient, for example, an aortic valve. The valve comprises a proximal region comprising a cylindrical shape, and a distal region having a generally rectangular shape comprising opposing flat surfaces that are separated by narrower flat sides. A tapered region is disposed between the proximal and distal regions, where the tapered region comprises two opposing flat surfaces that transition into the opposing flat surfaces of the distal region. The opposing flat surfaces of the tapered region are angled relative to the proximal and distal regions. The opposing flat surfaces at the distal end of the valve allow fluid flow therethrough during antegrade flow and are generally adjacent to one another to inhibit blood flow through the valve during retrograde flow. Optionally, at least one reinforcement member may be coupled to the valve to prevent prolapse of the valve during retrograde flow.

    摘要: The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

    摘要: A prosthesis may be used for treatment of an aneurysmal body vessel. The prosthesis may include a prosthetic trunk and a prosthetic branch. The prosthetic trunk may include a graft body, an open first end, an open second end, and a trunk lumen extending therebetween. The prosthetic branch may include a graft body, an open first end, an open second end, and a branch lumen extending therebetween. The first end of the prosthetic branch may be attached to the prosthetic trunk, and the branch lumen may be in fluid communication with the trunk lumen. The prosthetic branch may be movable in relation to the prosthetic trunk between neutral, right biased, and left biased configurations. First and second releasable steering members may be associated with the respective first and second biased configurations and may cooperatively retain the prosthetic branch in the neutral configuration.

    摘要: The present invention provides apparatus and methods for deployment of a modular stent-graft system. In one embodiment, a prosthesis comprises a first tubular graft comprising a layer of graft material, at least one lumen extending longitudinally therein, and a first fenestration extending through the layer of graft material. A layer of fenestration covering material attaches to the layer of graft material. The layer of fenestration covering material is disposed in the lumen of the first tubular graft and partitions the first fenestration from the lumen of the first tubular graft. A first non-stented opening is disposed proximal to the first fenestration and communicates with the first fenestration between the layer of graft material and the fenestration covering material. In use, a proximal end of a second tubular graft sealably engages the first non-stented opening, and the second tubular graft further extends through the first fenestration and into a branch vessel.
