  • Publication number: 20230398006
    Abstract: A stent having a substantially tubular body is disclosed. In at least one embodiment, the stent provides a scaffold having a plurality of interconnected struts forming a plurality of radial axial rows of radial support cells and a plurality of flexible axial rows of flexible support cells. The plurality of radial axial rows and flexible axial rows are disposed in an alternating pattern along a circumferential axis of the stent. A center axis of each radial axial row and flexible axial row is parallel to a longitudinal axis of the stent. Each radial axial row is arranged so as to be offset along the longitudinal axis of the stent from each adjacent radial axial row. Each radial support cell is formed from four of the interconnected struts of the scaffold which are arranged so as to be symmetrical along both the longitudinal axis and the circumferential axis of the stent.

  • Patent number: 11753755
    Abstract: A braided tube formation apparatus and associated methods of use are disclosed for assisting in the manufacture of a braided tube. In at least one embodiment, the apparatus provides at least one elongated core mandrel, and at least one elongated, radially collapsible primary tube sized and configured for removably receiving the at least one elongated core mandrel therewithin. Each of the at least one primary tube provides a plurality of spaced apart primary tube portions circumferentially arranged and configured for cooperating to define said primary tube. During use, after the braided tube is circumferentially formed on an outer surface of the at least one primary tube, the at least one core mandrel is removed from within the at least one primary tube, thereby allowing the primary tube portions to radially move inwardly toward one another so that braided tube may be disengaged from the at least one primary tube.

  • Patent number: 11707290
    Abstract: The present invention pertains to a thrombectomy device comprising a cylindrical proximal portion and one or more radiopaque segments. The cylindrical proximal portion forms a stent frame having an outer lattice network of an outer plurality of interconnecting segments. The outer plurality of interconnecting segments are configured to exert a radial force against an inner wall of a blood vessel. The radiopaque segment is formed from a plurality of radiopaque wires extending from the outer stent frame to a central axis of the thrombectomy device along a length of the stent frame. The radiopaque segment converges to a tip along with the central axis.

  • Patent number: 11660217
    Abstract: The present disclosure relates to a stent delivery component, a stent delivery system and a stent system. In particular, a stent delivery component including a base and at least two clamping wings which are rotatably connected with the base, respectively, is provided. In one aspect, the stent delivery component can effectively enclose the stent to complete delivery. In another aspect, the stent delivery component is kept in line contact with an inner wall of a delivery catheter to reduce the contact area, thereby reducing the frictional resistance and being beneficial to reduce the operation difficulty and increasing the delivery efficiency.
