  • Publication number: 20190388108
    Abstract: Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.

  • Publication number: 20190336313
    Abstract: A system for removing a thrombus. The system includes an expandable device that maintains axially fixed engagement with the thrombus. The expandable device applies a first force to the thrombus according to surrounding vessel size. The expandable device applies a second force to the thrombus according to an increased vessel size to maintain axially fixed engagement.

  • Publication number: 20190201592
    Abstract: The invention provides devices and methods for aneurysm treatment using a material that minimizes susceptibility artifacts in MRA images. Since images are not obscured by susceptibility artifacts associated with the aneurysm treatment device, those images are useful and reliable for evaluating the success of treatment. The material is preferably a non-ferromagnetic metal alloy and may include one or a combination of cobalt, nickel, chromium, and molybdenum. In certain embodiments, the material is a 35Cobalt-35Nickel-20Chromium-10Molybdenum-Low Titanium alloy medical-grade material.

  • Publication number: 20190029692
    Abstract: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.

  • Publication number: 20180271683
    Abstract: Endovascular treatment of, for example, delayed cerebral vasospasm involves the placing of a microcatheter in the affected vessels followed by the teachings of the instant disclosure, which is clinically improved with comparison to stow infusion of a vasodilating compound. Systems, processes and self-expanding designed stents and stent-like members are featured whereas as stents and stent-like members are retrieved, nothing is left in the vessel.

  • Publication number: 20180125697
    Abstract: The present invention relates to fluid flow diversion in medical procedures, and, more particularly, to a valve assembly for preventing retrograde flow of urine from a collection device into a urinary catheter so as to reduce the risk of and/or prevent catheter-associated urinary tract infection (CAUTI). The valve assembly of the present invention is a discrete, stand-alone valve assembly configured to provide a fluid connection between a urinary catheter (e.g., Foley catheter), and a collection device (e.g., urine drainage bag) or the tubing for coupling the catheter to the collection device. The valve assembly is configured to permit antegrade flow of urine from the catheter into the collection device, while preventing retrograde flow of urine (e.g., backflow) from the collection device into the catheter, thereby reducing the risk of CAUTI.

  • Publication number: 20170086852
    Abstract: An embolization device for treating ischemic stroke is disclosed, having a surface, wherein the body portion is configured to have a radiopaque and electropositive surface under physiological conditions when the device is emplaced, which ionically binds a blood component in an amount effective to promote stability of device in situ to bind to a tissue component in an amount effective to increase adhesion of the device as compared to a device without an electropositive surface. Embolic coils being so delivered are electrolytically detachable in under 10 seconds, according to the disclosed vascular implant systems.
