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 configured to move between a collapsed configuration and an expanded configuration. The elongated tubular member may comprise at least one twisted filament, such as a knitted filament having a plurality of twisted knit stitches with intermediate rung portions extending between adjacent twisted knit stitches, or a plurality of helical filaments twisted with a plurality of longitudinal filaments.

摘要： A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.

摘要： A stent which has a cylindrical tubular shape in which wires cross each other and are woven includes first regions each including a horizontal folding crossing portion in which the wires are folded in an axial direction and cross each other and a vertical folding crossing portion in which the wires are folded in a circumferential direction and cross each other. The first region is a region in which the horizontal folding crossing portion and the vertical folding crossing portion are arranged in the circumferential direction, and the first regions are arranged at intervals in the axial direction.

摘要： A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

摘要： A heart valve assembly includes an inner frame comprising a graft covering housing a prosthetic heart valve, wherein the graft covering extends around the prosthetic heart valve for providing sealing to the heart valve, an outer frame formed from a metallic material and defining a gridded configuration, and being secured to the graft covering by a plurality of stitches, and a sealing material positioned externally to the outer frame for providing sealing between the outer frame and a patient's anatomical wall to prevent paravalvular leaks. The sealing material includes a plurality of radially extending fibers that extend outwardly of the outer frame. The graft covering is made of polyester, polytetrafluoroethylene, expanded polytetrafluoroethylene, or a polymer.

摘要： In some examples, the disclosure describes a medical assembly that includes a stent including a primary electrode, where the stent is configured to expand from a collapsed configuration to an expanded configuration, a secondary electrode, and an energy source configured to deliver an electrical signal between the primary electrode and the secondary electrode through a fluid in contact with the primary electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.

摘要： A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.

摘要： A method of shunting blood involves accessing a left atrium of a heart with a surgical instrument, advancing the surgical instrument into a pulmonary vein fluidly coupled to the left atrium, forming an opening in a wall portion of the pulmonary vein, and shunting blood from the pulmonary vein into a right-side structure of the heart through the opening in the wall portion of the pulmonary vein.
