  • Patent number: 10507124
    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.

  • Publication number: 20190298909
    Abstract: Exemplary embodiments comprise AV fistulas and other anastomotic devices for creating new or reinforcing existing side-branch vessels, and/or bridging neighboring vessels together. An exemplary embodiment may comprise a sidewall port, such as a flanged sidewall port, and/or flow frame design, such as a partially bare, flexible stent or a whisk, for purposes of creating a transmural flow. Another exemplary embodiment may comprise a compliant vessel support to aid in the transition from device to vessel and/or vessel to device, and to promote vessel dilation.

  • Publication number: 20190282356
    Abstract: A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath.

  • Publication number: 20190216592
    Abstract: A stent graft including (1) a stent having a wall having at least one opening, an outer surface, and an inner surface and (2) a covering of a composite material having a least one expanded fluoropolymer membrane and an elastomer is provided. The cover can be used to cover the outer and/or the inner surface of the stent. The expanded fluoropolymer membrane contains serpentine fibrils. In exemplary embodiments, the fluoropolymer is polytetrafluoroethylene. The composite material may be axially and/or circumferentially wrapped around the stent. The composite material is fold-free throughout its operating diameter range and exhibits a sharp increase in stiffness at a predetermined diameter. The stent graft can be designed to have a stop point in either a radial or axial direction. The stent graft can advantageously be implanted undersized with respect to a nominal diameter without having material infolding.

  • Publication number: 20190125517
    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: 20180263802
    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.

  • Publication number: 20180193177
    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.

  • Publication number: 20180154108
    Abstract: A multi lumen catheter assembly. The assembly provides an expandable, low profile, fixed length sheath and catheter, with fixed infusion ports. The assembly has an expandable outer sheath that expands upon pressure activation with a fluid and the sheath allows the fluid to exit from at least one predetermined fixed location from a distal end of the catheter assembly. The catheter assembly can be used in various medical device procedures, such as a TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure, or anywhere a low profile, multi lumen, infusion catheter system is desired.
