  • Publication number: 20230149148
    Abstract: A system used to entrap clots in arteries, such as cerebral arteries, between the artery wall and an external surface of a stent to provide restoration of blood flow therethrough that includes a stent forming an annular wall that defines a set of openings, and an expansion member extendable through the stent to place a distal portion thereof distal to the stent. The stent is advanced into a clot disposed within a vessel and transitioned to an expanded configuration such that the annular wall engages the clot. The expansion member extends through the stent and is transitioned to an expanded state such that a diameter of the distal portion is greater than a diameter of a proximal portion thereof. The expanded distal portion is sized to fill a portion of the vessel to prevent clot fragments from flowing distal to the expansion member.

  • Patent number: 9925076
    Abstract: A stent in the form of a generally tubular body has multiple annularly expandable serpentine elements. The serpentine elements have arcs at the first and second element ends which point in the axial direction of the stent. Annularly expandable serpentine elements which follow one another in the axial direction are connected to one another via connectors which are arranged at the ends of the adjacent elements. The connectors extend in the circumferential direction of the stent in the non-expanded state of the stent and have a curvature in the circumferential direction. In the expanded state of the stent, the curvature is so great in the circumferential direction that the connectors project radially outward beyond the circumference of the serpentine elements.

  • Patent number: 8834558
    Abstract: A flexible stent and method for performing a stent within a lumen proximate to a target area is provided. The stent includes a tubular member having proximal and distal ends, where at least a portion of the tubular member is capable of being positioned proximate to the target area. The stent also includes a plurality of stabilization members defined circumferentially about at least a portion of the tubular member, wherein each stabilization member extends inwardly to define an inner diameter that is less than an inner diameter of the tubular member within the tubular member. As a result, the stabilization members are capable of reducing migration of the stent within the lumen and the incident of infolding of the tubular member.

  • Patent number: 7942921
    Abstract: The invention is relative to a stent with a tubular support frame consisting of axially successively following, interconnected annular segments, which support frame is surrounded on its outside by a thread. The thread ends are guided via a deflection from the outside into support frame, where they are coupled by a connector consisting of a material visible in x-rays. Deflection is realized by two deflection elements in the form of eyelets provided on annular segment. Deflection elements are arranged on the circumference of support frame at an interval from one another and are provided on end-side annular segment, viewed in longitudinal direction L of the stent.

  • Patent number: 7691142
    Abstract: A stent (1) is a vascular prosthesis for a constricted body vessel. The stent (1) includes a tubular support frame (2) of ring segments (3) arranged in axial succession and formed by struts (5, 6) which in initial state are joined continuously in a wave-like manner. Adjacent ring segments (3) are linked by differently long connectors (9, 10) with U-shaped compensating sections (11, 12). All connectors (9, 10) point in the same circumferential direction (U). Moreover, differently long connectors (9, 10) alternate in circumferential direction (U) as well as in longitudinal stent axis (L).

  • Patent number: 7645297
    Abstract: Disclosed is a stent (1) representing a prosthesis for a constricted body vessel. The stent (1) includes a tubular support frame (2) composed of ring segments (3, 4, 5) which are sequentially arranged in axial direction and which are formed by segment struts (5, 6) that are continuously joined to one another in the initial state via transitions (8). Adjacent ring segments (3-5) are coupled to each other using tie bars (9, 10). In order to prevent notch stress in the segment struts (5, 6), the width thereof increases from midsection (16) in the direction of the transitions (8), wherein the segment struts (6, 7) are curved in a wave-like manner.
