摘要： Low radial force stents with good resistance to migration are described comprising microstructured surfaces which generate inward radially directed grip to a lumen. In particular, stents are described for deployment within biological lumens where a novel combination of low outwardly directed radial force and resistance to shear slippage within the lumen is achieved by hierarchical microstructured surfaces which provide non-frictional grip to the luminal surface. Combinations of microstructured surfaces which combine low radial force frictional grip and non-frictional grip which do not rely on axially dependent changes in stent diameter or stent oversizing are described. These combinations of microstructured surfaces when placed on the outer surface of a stent provide a non-migrating stent. The hierarchical levels of the disclosed microstructures may themselves by composites of microstructures, which may or may not be self-similar to other hierarchical levels.

摘要： A heart valve repair system includes a delivery sheath and an implant that includes a frame including a braided structure of intertwining strands and having a surface configured to contact an upstream surface of a native heart valve. First and second gripping members are coupled to the frame, each including atrial and ventricular arms. The implant is disposed in the sheath in a delivery state in which the frame defines a wall fully surrounding a central longitudinal axis of the implant. The distal end of the wall defines a distal opening of the frame. The distal end of the wall is disposed proximally to the second end of the ventricular arm of each of the gripping members. The second end of each ventricular arm moves toward the axis of the implant more than the first end moves toward the axis. Other embodiments are also described.

摘要： Disclosed are implant and method for gradually restricting vascular blood flow in a host blood vessel. The implant N comprising an elongated body and at least one holding member. Implant body comprising a flow restricting portion enclosing a variable minimal internal diameter. Holding member is configured for restraining implant body to maintain the variable minimal internal diameter in a first minimal internal diameter, and to physically yield voluntarily after a first predetermined average duration of being continuously subjected to internal human body conditions, thereby releasing and allowing the implant body to elastically deform voluntarily such that the variable minimal internal diameter changes to a second minimal internal diameter, smaller than the first minimal internal diameter.

摘要： A mandrel for forming a stent with a tapered profile and one or more anti-migration features includes a first stent shaping segment having a first diameter, a second stent shaping segment having a second diameter less than the first diameter and a tapered segment disposed therebetween. A third stent shaping segment is releasably securable to the second stent shaping segment and has a third diameter greater than the second diameter. One or more movable pins are outwardly extendable from corresponding apertures formed within the tapered segment. An actuation element is engagable with the first stent shaping segment and includes a tapered surface configured to engage the one or more movable pins and support the one or more movable pins extended from the corresponding apertures.

摘要： The disclosure provides example apparatus and methods. One example apparatus includes a first woven stent having a curved form in an expanded state. In the expanded state, at least a first portion of the first woven stent has a weave pattern arranged along an outer curvature of the first woven stent that is different than a weave pattern arranged along an inner curvature of the first woven stent. And the first woven stent is biased toward the curved form due to shape memory.

摘要： A prosthetic heart valve implant is provided including a frame shaped so as to define upstream and downstream openings at upstream and downstream ends of the frame, respectively, when the implant is in an expanded state for implantation at a heart native valve. A sheet is coupled to the frame. When the implant is in the expanded state, the frame is shaped so as to define the following longitudinal portions arranged along a central longitudinal axis of the prosthetic heart valve implant: a substantially cylindrical mid portion having a diameter greater than respective diameters of the upstream and the downstream ends of the frame; an upstream portion, extending upstream and radially inward from the mid portion; and a downstream portion, extending downstream and radially inward from the mid portion. Other embodiments are also described.

摘要： An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member may include at least one flexible tie affixed to an end thereof. The tie may allow the stent to be attached to a lumen wall with a clip, such as a retention clip, to inhibit migration of the stent within the body lumen.

摘要： Apparatus and methods are described including implanting an aortic pressure-loss-reduction device in a subject's ascending aorta. While the device is inside a catheter, a distal end of the catheter is placed within the ascending aorta. A proximal covering sheath of the catheter is retracted such as to uncover at least a portion of a downstream anchor, such that the uncovered portion of the downstream anchor includes a portion of the frame that does not have material coupled thereto. Subsequently, a distal covering sheath of the catheter is advanced, such as to cause an upstream anchor to anchor an upstream end device to the subject's ascending aorta, by the upstream anchor radially expanding against an inner wall of the ascending aorta. Other applications are also described.
