  • Patent number: 9675479
    Abstract: Stents (10) that are implanted within or around a hollow organ, especially self-expanding stents, comprising several annular wall segments (11) which are provided with an elastic structure and are joined to each other by means of connecting elements (12), are often problematic because the length of said stents is modified due to compressive stress, tensile stress, or contraction thereof, potentially resulting in undesired displacement of the stent (10). In order to prevent such positional changes of an implanted stent (10), the inventive connecting elements (12) form at least one continuous longitudinal web (13) which is provided with at least one component in an axial direction for receiving compressive stress or tensile stress in a longitudinal direction.

  • Patent number: 9655721
    Abstract: The invention relates to an implantable device for use in the human and/or animal body to replace an organ valve, comprising a main body having a first end and a second end, wherein the first end and the second each have an opening to provide a fluid connection through the main body between the first end and the second end; a first membrane element arranged inside or at one end of the main body, wherein the membrane element is formed in such a manner that it allows the fluid connection through the main body in a first flow direction and blocks the same in a second flow direction opposite the first flow direction; wherein the main body has a large ratio of length to transverse expansion along the longitudinal axis of the main body in a first operating state (primary form) and a smaller ratio of length to transverse expansion along the longitudinal axis of the main body in a second operating state (secondary form); and wherein the main body can be reversibly transferred from the secondary form to the primary fo

  • Patent number: 9320629
    Abstract: A stent for positioning in a body lumen having a cylindrical shape extending along a longitudinal axis surrounded by a stent wall which defines a diameter of an axial passage communicating with openings on two opposite ends of the stent. The wall is configured so as to be elastic under tension whereupon an exertion of a tensile force acting on one of the ends of the stent in a longitudinal direction decreases the diameter of the stent, such that the stent may be removed.

  • Patent number: 9101502
    Abstract: The invention relates to a stent comprising terminal anchoring elements. Said stent (10) is provided with a tubular wall that extends along a longitudinal, flexible tubular axis (26), is formed from a flexible grid structure, and has tube ends (20) lying on opposing axis ends. Said wall consists of annular wall segments (11) that are lined up along the axis and are interconnected by means of connection segments (12). The annular wall segments (11) contain wall elements (14, 15) having an elastic structure.

  • Patent number: 8828051
    Abstract: A left atrial appendage occlusion device including an occluder disk configured to substantially prevent blood from at least one of entering and exiting the left atrial appendage, a middle portion including a coiled element and a first anchoring element. The coiled element connects to the occluder disk, has a substantially constant cross section and allows for variable length, variable orientation, and/or varied angles. The first anchoring element connects to the coiled element and includes scalloped edges that are configured to anchor the occlusion device to inner walls of the left atrial appendage and reduce the risk of one of penetration and perforation of walls of the left atrial appendage. The left atrial appendage occlusion device may also include a self-centering element that connects to the occluder disk and middle portion and is configured to center the occlusion device within the orifice of the left atrial appendage.

  • Patent number: 8066734
    Abstract: To bring about an improvement in comparison with known implants, in particular with regard to economical mass production, an implant for the closing of defect openings in the body of a human or animal is proposed, with a load-bearing structure which, in a first operating state (primary form), has a great ratio of length to transverse extent along an axis and, at least in a further operating state (secondary form), has a much smaller ratio of length to transverse extent along the axis, the load-bearing structure being capable of being reversibly transformed from the secondary form into the primary form by exertion of a force against elastic material forces, the secondary form assuming approximately the form of a double disc with a proximal disc element and a distal disc element for receiving the surroundings of the defect opening between the disc elements, and the load-bearing structure being formed essentially in one piece without joining connections, and a placement system, in particular for such an implant,
