  • Patent number: 11090177
    Abstract: A delivery catheter comprises an inner shaft and an outer sheath. A stent-graft is held on a region of the inner shaft. An enlarged diameter distal region of the outer sheath constrains the stent-graft. Its retraction allows the stent-graft to deploy. A finger wheel on a handle is used to retract the outer sheath and is coupled to a sliding block with cable(s). The sliding block is coupled to the outer sheath and is held within a sliding track. The wheel can be actuated to tension the cable(s) and deform latch(es) coupled to sliding block, freeing them from slot(s) in the sliding track and allowing retraction of the sliding block and the outer sheath. A reinforcement sleeve is coupled to a smaller diameter proximal region of the outer sheath. A gap between the outer sheath distal region and the reinforcement sleeve allows the distal outer shaft region to be retracted.

  • Patent number: 11020253
    Abstract: The present invention relates to a multi-hole stent for digestive organs, the multi-hole stent including: a body configured to form a plurality of cells through the intersection of wires and to be provided in a hollow cylindrical shape; and a film configured to be installed in contact with the inner surface of the body; wherein one or more discharge holes are formed in the film. The multi-hole stent for digestive organs is placed in a stenotic region in a biliary track, and can thus secure a discharge path by restoring a narrowed diameter. Furthermore, the film is installed on the inner surface of the body, and can thus prevent the entry of a lesion into the stent and re-stenosis attributable to the growth of the lesion and can thus provide discharge paths for body fluids generated from side branches through the discharge holes formed in the film.

    Abstract: An implantable vein frame is contemplated in which two ring members are rigidly joined in spaced axial alignment via one or more interconnecting members. One of the one or more interconnecting members defines a protruding region that acts upon the implant placed within the frame and/or the vein that the vein frame is placed within to define a sinus region. The implant is placed within and scaffolded by the vein frame, and the vein frame is subsequently inserted within a vein via a venotomy, or interposed between two vein segments via vein interposition graft. The vein frame acts to support the structural integrity of the implant, and to scaffold and anchor the implant in place with the vein.

The mesh structure has a relaxed configuration in which it has an axial array of radially-extending occlusion regions, each of which has a proximal side and a distal side meeting at a peripheral edge, the sides of each occlusion region forming a first angle relative to the longitudinal axis. Each occlusion region is axially separated from the adjacent occlusion region by a reduced-diameter connecting region.

    Abstract: The present disclosure describes intraluminal support devices having high radial stiffness regions with smaller diameter and low radial stiffness regions with larger diameter. When deployed to the vasculature of a patient in need of treatment, the high radial stiffness region is sized such that it has approximately the diameter of the vessel in need of treatment, so that it produces substantially zero chronic radial force when the vessel is not being subjected to external compression. The low radial stiffness regions anchor the device to the vessel wall and provide a less-abrupt transition from the high radial stiffness structure. Methods of making and using such devices are also described.

    Abstract: A router device is a intraluminal prosthesis which is used in the repair of aneurysms and other diseases of the aorta. The device also has applications in other vascular beds. The device incorporates an inflatable cuff or sequence of cuffs at one end for fixation and sealing. This cuff may be placed proximal to branch vessels of the aorta. Attached to the cuff is a tubular graft consisting of a generally cylindrical graft material. The graft material may contain one or more fenestrations, intended to align with branch vessels as they emerge from the parent vessel, the aorta in the preferred embodiment. The device features a deliberate taper of its diameter as the device crosses the area of branch vessels. This taper brings the diameter of the graft material to a lesser diameter than that of the parent vessel, leaving a deliberate and distinct space between the device and the wall of the vessel.

    Abstract: An endovascular apparatus is provided for treating the effects of vascular disease including aneurysms and arterial blockages using a percutaneous, minimally invasive technique. In one embodiment the endovascular apparatus includes a tubular sleeve having a cranial end, a first caudal branch, and a second caudal branch such that the tubular sleeve is shaped like an upside down “Y.” The apparatus further includes at least one expandable attachment device attached to the tubular sleeve for securing the endovascular apparatus to an interior wall of a vessel. The at least one expandable attachment device includes a plurality of telescoping segments similar to the telescoping segments of a presentation pointer. Accordingly, during percutaneous insertion of the endovascular apparatus into a patient the attachment device can be collapsed into a small profile.

  • Patent number: 9895241
    Abstract: A medical device includes a polymer stent scaffold crimped to a catheter having an expansion balloon. A process for forming the medical device includes placing the scaffold on a support supported by an alignment carriage, and deionizing the scaffold to remove any static charge buildup on the scaffold before placing the scaffold within a crimper to reduce the scaffold's diameter. The polymer scaffold is heated to a temperature below the polymer's glass transition temperature to improve scaffold retention without adversely affecting the mechanical characteristics of the scaffold when deployed to support a body lumen.

  • Patent number: 9833625
    Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming a first inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath forming a second inner lumen. An outer diameter of the inner sheath is smaller than the diameter of the first inner lumen such that the inner sheath fits within the first inner lumen, wherein the inner sheath is slidable within the first inner lumen. The second inner lumen at a distal end of the inner sheath is configured to carry an implantable medical device. The inner sheath forms a slit at a distal end of the inner sheath to facilitate deployment of the implantable medical device out of the distal opening of the outer sheath.

  • Patent number: 9808365
    Abstract: An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (22) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

  • Patent number: 9694108
    Abstract: The present invention is directed to a device that permits a permanent aperture to be formed in a wall, or other partition, of an implantable medical device. The present invention maintains the continuity and fluid-retaining properties of the implantable medical device by providing a breachable barrier material fully covering an opening delimited by a deformable framework. The invention is accessed with conventional interventional surgical instruments that disrupt and displace the barrier material. Following disruption of the barrier material, the opening is enlarged with surgical instruments to form a permanent framed aperture in the wall of the implantable medical device. The permanent framed aperture provides fluid communication across the wall of the implantable medical device.
