  • Publication number: 20210077246
    Abstract: A diametrically adjustable endoprosthesis includes a controlled expansion element extending along at least a portion of a graft and is supported by a stent. The controlled expansion element diametrically constrains and limits expansion of the endoprosthesis. Upon deployment from a smaller, delivery configuration, the endoprosthesis can expand to the initial diameter set by the controlled expansion element. Thereafter, the endoprosthesis can be further diametrically expanded (e.g., using balloon dilation) by mechanically altering the controlled expansion element.

  • Publication number: 20210068996
    Abstract: The invention relates to medical devices and methods of using them. The devices are prostheses which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The prostheses are configured to have a lattice resistant to dilation and creep, which is defined by a plurality of openings. The prosthesis may also optionally have a stent disposed proximal to the lattice. In exemplary embodiments, the fluoropolymer is expanded polytetrafluoroethylene. The composite materials exhibit high elongation while substantially retaining the strength properties of the fluoropolymer membrane. In at least one embodiment, the lattice is made of a composite material that includes a least one fluoropolymer membrane including serpentine fibrils and an elastomer. A lattice including a generally tubular member formed of a composite material including a least one fluoropolymer membrane containing serpentine fibrils and an elastomer is also provided.

  • Patent number: 10932930
    Abstract: A retrieval device includes an elongate element having a collapsible retriever at its distal end, wherein the collapsible retriever can be axially delivered over or through an introducer to the site of an object to be retrieved, e.g., a failed endoluminal device. When the retrieval device reaches the failed endoluminal device, the endoluminal device and the retrieval device are withdrawn together through the introducer. The introducer is configured to force the retrieval device down over the endoluminal device reducing the french size of the spent endoluminal device upon extraction. The collapsible retriever can be configured to side-mount a delivery element, or it can be integrated into a delivery system.

  • Patent number: 10881426
    Abstract: Various embodiments provide a device comprising a balloon assembly including a balloon, a film template, and a rigid element. The film template may have a fixed upper distension limit and may include at least one aperture. The rigid element may lay substantially flush with an outer surface of the balloon at a first inflated state of the balloon. The first upper distension limit of the balloon may be greater than the fixed upper distension limit of the film template and the balloon may outwardly protrude through the at least one aperture at a second inflated state. The rigid element may be extended in a radial direction away from the outer surface of the balloon as the balloon outwardly protrudes through the at least one aperture relative to the outer surface of the film template.

  • Patent number: 10842918
    Abstract: A length extensible implantable device includes a porous member and a longitudinal constraining member. The longitudinal constraining member can constrain at least a portion, up to the entire length of, the porous member in the longitudinal direction. The length of the longitudinally constrained portion can be expanded by applying force to the porous member. The porous member may be a porous tubular member.
