  • Patent number: 12678306
    Abstract: An endoprosthesis having a length, a first end, a second end, and a longitudinal axis is disclosed herein, where the endoprosthesis is expandable from a compact, delivery configuration to an enlarged, deployed configuration. The endoprosthesis includes a plurality of rows of stent elements along the length of the endoprosthesis, where the plurality of rows include a first row and a second row located adjacent to the first row. The first row of stent elements has a first plurality of alternating apices, and the second row of stent elements has a second plurality of alternating apices. The first and second pluralities of alternating apices define a spaced apart, interlocking arrangement. The endoprosthesis also includes a discontinuous web of material comprising a plurality of web elements spaced from one another and interconnecting the first and second pluralities of alternating apices.

  • Publication number: 20260157868
    Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.

  • Patent number: 12502292
    Abstract: A medical device frame including an undulating frame element defining a series of peaks each defining a longitudinal splay angle, circumferential cant angle, or combinations thereof. In some examples, the series of peaks are non-overlapping when the frame is in an expanded configuration and overlap when the frame is in the collapsed configuration. The longitudinal splay angle and/or circumferential cant angle may remain relatively unchanged between the expanded and collapsed configurations (e.g., within about 15%).

  • Publication number: 20250339227
    Abstract: A medical device deployment apparatus that employs a first actuation line and a second actuation line, whereby a delay is sought between initiation of the actuation of the first actuation line and actuation of the second actuation line. Prior to actuation, the first actuation line includes sequentially aligned multiple loops, wherein the multiple loops provide predefined slack to delay linear actuation of the first actuation line when tension is applied to both the first and second actuation lines.

  • Patent number: 12447030
    Abstract: The present disclosure comprises devices, systems, and methods having an inverted sheath configured to cover, and in some instances constrain, a medical device and to retract through eversion, thus enabling the deployment of medical device at the treatment site. A constraining sheath can evert hydraulically. A constraining sheath can be configured to neck down a medical device to achieve a lower delivery profile. Furthermore, a constraining sheath can comprise a balloon to expand or positionally or structurally adjust a medical device.

  • Publication number: 20250243563
    Abstract: A wire of a nickel-titanium alloy having a permanent set of less than 5% when 11% strain is applied to the wire is disclosed. The wire may be formed by applying a first heat treatment to the wire, the first heat treatment includes applying heat of a first temperature for a first period of time, applying a strain deformation to the wire to set a shape for the wire during the first heat treatment, and applying a second heat treatment to the wire. The second heat treatment includes applying heat of a second temperature different from the first temperature for a second period of time, and the second temperature is between 210° C. and 290° C. The wire has a modulus of at least 53 GPa when 200 MPa of stress is applied to the wire.

  • Patent number: 12310871
    Abstract: An implantable medical device deployment system is disclosed that employs both a sheath element and a constraint member to protect implantable medical devices during delivery in a body while providing simple, accurate, and reliable device deployment. The delivery system is configured so that loading and deployment forces are not directly related to device diameter, length, or design, thus allowing a more universal delivery system across various delivered device configurations and product lines. The deployment system can provide numerous benefits, include better protection for drug-coated implantable devices.
