摘要： A percutaneous, transluminal, angioplasty system includes a non-foreshortening stent and a stent anchor to hold the stent in place until delivery. The stent comprises rings and fused rings comprising various motifs such as butterfly or pinched ellipsoid motifs. Stent anchors can release the stent after an outer sheath uncovers the stent or uncovers the stent and biased or bent fingers of the stent anchors.

摘要： Prosthetic valves and methods of using prosthetic valves may be provided. In one implementation, an expandable annular valve body may include a plurality of atrial anchoring arms and ventricular anchoring legs extending radially outward therefrom. At least one atrial anchoring arm may include a rigid portion and a flexible portion positioned radially outwards from the rigid portion. At least one atrial anchoring arm and at least one ventricular anchoring leg may be arranged such that a proximal section of the flexible portion of the at least one atrial anchoring arm and a terminal leg end of the at least one ventricular anchoring leg are substantially equidistant from a longitudinal axis extending through the center of the annular valve body.

摘要： Prosthetic valves and methods of use of prosthetic valves may be provided. In one implementation, a method of releasing a prosthetic valve from a delivery capsule within a heart may be provided. The delivery capsule may include a distal capsule portion and a proximal capsule portion. The method may include moving the distal capsule portion in a first direction to release ventricular anchoring legs of the prosthetic valve from the delivery capsule and moving the released legs into contact with a native mitral valve. The method may include moving the proximal capsule portion in a second direction to release atrial anchoring arms of the prosthetic valve from the delivery capsule, after contacting the mitral valve with the released legs. The method may include moving the distal capsule portion in the first direction to release an annular valve body of the prosthetic valve from the delivery capsule.

摘要： A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stented valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

摘要： An aortic bare stent and an aortic dissection stent are disclosed. The aortic bare stent is in a tubular net structure, with multiple support stents in circles and arranged along an axial direction. Two adjacent support stents are connected by a connector stent. The connector stent is made of a hyper-elastic material. A flexural rigidity of the connector stent is less than that of the support stent. The support stent is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material.

摘要： An anastomosis stent includes an elongated body of a tubular configuration having a length and diameter dimensions extending in axial and radial directions of the elongated body and in a transverse relationship to each other. The elongated body is formed by multiple rings stacked adjacent one another in a direction parallel to the length dimension. Each ring is a single strand of wire bent in a repetitive pattern of sine waves. Each sine wave defines an alternating peak and valley divided by a length dimension extending orthogonal to the length dimension of the elongated body. The rings are fused together at locations on selected pairs of adjacent peaks and valleys of the rings with the fused locations arranged in parallel rows. The elongated body includes main and end portion and a safety mark about the elongated body at the juncture therebetween.

摘要： An implantable frame comprises a plurality of corner structures configured to decrease pressure to the vessel wall and define pulsatility enhancing windows of the implantable frame. The corner structures may comprise plurality of neighboring longitudinal struts that extend in a longitudinal direction of the blood vessel when placed to form the vessel wall to a substantially polygonal cross-section and distribute pressure loading of the corner structure among the plurality of neighboring longitudinal struts to improve biocompatibility. The corner structures also allow increased forming of the vessel wall and can provide stretching of the vessel wall to enhance pulsatility of the vessel wall.

摘要： An arterial anchor device operably coupled by graft material to form an anastomotic connector is provided. The arterial anchor device comprises a generally tubular main body including a distal end and a proximal end, the distal end defining a plurality of flanges integrally formed with the tubular main body and being movable from a first loaded position to a second expanded position. The arterial anchor device is fluidly connected by a graft to form an anastomotic connector.
