  • Patent number: 10441447
    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: An introducer assembly includes a distal sheath and a proximal sheath. A splitting element is located at a proximal end of the distal sheath and is arranged to split the distal sheath in a distal direction, so as to deploy first a branch element of a medical device and thereafter the distal end of the medical device. The proximal sheath can then be retracted to release the proximal end of the medical device. Deployment of the medical device from the branch element first enables accurate positioning of the branch element prior to deployment of the main body portion of the medical device.

    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.

  • Patent number: 10137018
    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.

  • Patent number: 9597212
    Abstract: An implant delivery system is disclosed. The delivery system includes an elongated member having an implant mounting location. A self-expandable implant is mounted at the implant mounting location. The implant is held in a compressed orientation by a retractable sheath. An interlock structure prevents the implant from deploying prematurely as the sheath is retracted. The interlock structure includes radio-opaque markers that identify the position of the implant.

  • Patent number: 9585670
    Abstract: A medical flow restrictor that may be used to exclude a saccular aneurysm from the circulatory system. The device, a thin walled, foil-like shell, is compacted for delivery. The invention includes the device, electroforming fabrication methods, delivery assemblies, and methods of placing, and using, the device. A device with an aneurysm lobe and an artery lobe self-aligns its waist at the neck of an aneurysm as the device shell is pressure expanded. Negative pressure is used to collapse both the aneurysm lobe and the artery lobe, captivating the neck of the aneurysm and securing the device. The device works for aneurysms at bifurcations and aneurysms near side-branch arteries. The device, unlike endovascular coiling, excludes the weak neck of the aneurysm from circulation, while leaving the aneurysm relatively empty. Unlike stent-based exclusion, the device does not block perforator arteries. This exclusion device can also limit flow through body lumens or orifices.

  • Patent number: 9492150
    Abstract: An apparatus for sealing a passage through tissue communicating with a blood vessel includes a bioabsorbable plug member coupled to the distal end of a carrier member. The plug member includes a lumen extending therethrough that communicates with a lumen extending through the carrier member. A sealing member is disposed in the plug member lumen for sealing the lumen. A guide member is slidable into the lumen such that edges of a groove extending between proximal and distal portions of the guide member engage a wall of the lumen to define a bleed back lumen. The guide member is inserted into the passage until the distal portion enters the vessel. The plug member is advanced over the guide member until the plug member enters the vessel, whereupon blood enters the bleed back lumen to identify the location of the vessel relative to the plug member.

  • Patent number: 9456915
    Abstract: Upon filling multiple inflatable chambers of a gastric balloon structure in a patient's stomach, the gastric balloon structure assumes a natural three-dimensional kidney shape of the gastric cavity. A flexible central spine may span a gap between two inflatable chambers and may include lumens for inflation of one or both chambers. The plurality of compartments, when in an inflated state, may form a cavity therebetween through which food may pass and may leave in a stomach a residual volume of 10 ml to 100 ml.

  • Patent number: 9452069
    Abstract: A reconfigurable delivery system is disclosed having a multi-lumen delivery catheter configuration that permits the delivery and staged release of a self-expanding main vessel stent-graft and a delivery sheath configuration that permits the introduction of various medical devices for the delivery and implantation of various branch vessel stent-grafts that are to be mated with the main vessel stent-graft. A method is disclosed wherein the delivery system is first used in the multi-lumen delivery catheter configuration to deliver and release a main vessel stent-graft that is configured for placement in the abdominal aorta for treatment of short-neck infrarenal, juxtarenal, and/or suprarenal aneurysms and then used in the delivery sheath configuration to facilitate the delivery of branch vessel stent-grafts that are configured to extend from the main vessel stent-graft into a respective renal artery.

  • Patent number: 9427216
    Abstract: Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from interventional procedures. The vessel wound closure system comprises at least a biocompatible, viscoelastic, self-sealing septum material injected onto the adventitia of the target vessel prior to performance of an interventional procedure. The prior injected septum material remains and seals the puncture wound of the target vessel even after various components associated with accessing the target vessel and the performance of the interventional procedure are removed from the target vessel and the puncture wound.
