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： 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： 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： Devices for delivering and deploying an endoluminal prosthesis are disclosed and comprise a delivery catheter, an endoluminal prosthesis disposed at a distal end portion of the delivery catheter, and a wire. The prosthesis comprises a tubular graft having at least one fenestration. The wire extends distally from a first wire end through an axial lumen of the delivery catheter and the prosthesis, and through the fenestration in the graft. The wire extends proximally through a lumen of the prosthesis and through an axial lumen of the delivery catheter towards a second wire end. Additional devices, systems, and methods are disclosed.

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.
