摘要： Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft comprises first and second stents, which each may comprise a series of distal apices disposed distal to a proximal end of the graft, and a series of proximal apices disposed proximally beyond the proximal end of the graft. In one example, the first stent comprises a first uniform segment, and the second stent comprises a second uniform wire segment, where the first uniform segment comprises portions disposed both internal and external to the second uniform wire segment.

摘要： A stent graft (10) has a tubular body with a side aperture (16) covered by a valve arrangement (18) and an arrangement to hold the valve open (32) with a release wire (30). Retraction of the release wire closes the valve. The stent graft can have a tubular body with a first bifurcation (134) with first and second legs (130, 132) extending from the bifurcation. The side aperture and valve arrangement can be in one of the legs. One of the legs (132) has a further bifurcation (142) to define a side arm (140). The stent graft can be deployed into the vasculature of a patient with the tubular body being in an aorta of the patient, a first leg extending down an iliac artery, a second leg being directed towards a contralateral iliac artery and the side arm directed to an internal artery of the contralateral iliac artery.

摘要： An implantable medical support frame (104) having a central longitudinally extending axis is expandable from a collapsed configuration having a first diameter to an expanded configuration having a second diameter. The frame also includes an anchoring mechanism with an elongate member (110). At least a portion of the elongate member is slidably disposed within a retaining structure when the frame is in the collapsed configuration. When the frame expands from the collapsed configuration to the expanded configuration, a portion of the elongate member is advanced out of the retaining structure such that the portion of the elongate member protrudes radially outward of the frame at an angle to the axis, thereby forming an anchor. A length of the protruding portion of the anchor increases as the frame expands from the collapsed configuration to the expanded configuration.

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.

摘要： The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. A trigger wire is adapted to be coupled to at least one of the proximal apices to restrain a proximal end of the stent during delivery. In a first embodiment, a first proximal apex comprises a bore for receiving the trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. The trigger wire therefore is only coupled to selected ones of the proximal apices. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

摘要： A hybrid stent (100) includes at least one resilient ring (105) comprising a superelastic wire (102) formed in a sinusoidal pattern of alternating crests (110) and troughs (115) about a circumference of the ring (105). A plurality of malleable cannula segments (120) overlie the superelastic wire at the crests and troughs. Each of the cannula segments (120) includes a bend (125) and has an inner diameter sized to allow relative motion between the wire (102) and the cannula segment (120). The hybrid stent (100) may also include a plurality of gaps (130), where each gap (130) is defined by a spacing between opposing cannula segments (120). Deformation of the malleable cannula segments (120) dominates a response of the stent to substantially uniform radial forces, and deformation of the resilient ring (105) dominates a response of the stent to radially nonuniform crushing forces.

摘要： A stent graft has a tubular side arm which can be angled proximally and distally and from side to side. The wall of the stent graft in the vicinity of the side arm has a loose fold of the graft material and the side arm is fastened to the loose fold of graft material. The tubular side arm has an inner end and an outer end and is fastened into the loose fold of graft material by a circumferential fastening around the tubular side arm between the inner end and the outer end so that the tubular side arm extends partially within the tubular body of the stent graft and partially outside the tubular body of the stent graft. The loose fold of graft material can be formed by the graft material defining a recess in the wall of the stent graft. To enable movement or angulation proximally and distally and from side to side the loose fold of graft material is provided both proximally and distally of the tubular side arm and circumferentially to each side of the tubular side arm.
