    Abstract: The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

    Abstract: The present embodiments provide a medical device for implantation in a patient-comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

    Abstract: The present embodiments provide stents and stent-grafts for use in medical procedures. In one embodiment, a stent comprises a series of proximal apices, a series of distal apices, and at least one imaging element. A first suture bore is disposed in a surface of the stent at a location distal to the imaging element, and is adapted to receive a suture for coupling a portion of the stent to a graft material. A distal region of the stent, including the series of distal apices and the first suture bore, overlaps with the graft material, while a proximal region of the stent, including the series of proximal apices and at least one barb, is disposed proximally beyond the graft material. In an alternative embodiment, a stent-graft comprises a graft, a first stent and a second stent, in which a series of proximal apices of the first stent are each disposed distal to the proximal end of the graft, and a series of proximal apices of the second stent are each disposed proximally beyond the proximal end of the graft.
