    摘要: 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 distal region of the stent, including the series of distal apices and a 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.

    摘要: A delivery system may include a stent-graft, a locking member, and one or more diameter reducing members. The stent-graft may include a tubular graft comprising first and second longitudinally extending sides disposed opposite each other and connected at a tangent line. When the locking member is in a locked position, the locking member restrains a surface of the graft against the cannula. The first diameter reducing member may be slidably connected to a first portion of the graft that is disposed proximate the tangent line and may be slidably connected to a second portion of the graft that is spaced circumferentially away from the tangent line. When the first diameter reducing member is in a restrained position, the second portion of the graft is drawn toward the first portion of the graft and the proximal portion of the stent-graft has a reduced diameter configuration with at least two lobes.

    摘要: 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.
