  • Patent number: 11786254
    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: 20180055666
    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 slow infusion of a vasodilating compound. Systems, processes and self-expanding designed stents and stent-like members are featured and highlighted. The stents and stent-like members being retrieved, nothing is left in the vessel. Drug-eluting stents, resorbable stents and angiographically imageable coatings, including tantalum brushes over part or all of subject system components are also disclosed.

  • Patent number: 9198687
    Abstract: An acute stroke recanalization system and processes include catheter-based improved reconstrainable or tethered neurological devices which are deliverable through highly constricted and tortuous vessels, crossing the zone associated with subject thrombi/emboli, where deployment impacts, addresses or bridges the embolus, compacting the same into luminal walls which enables perfusion and lysis of the embolus, while the improved neurological medical device itself remains contiguous with the delivery system acting as a filter, basket or stand alone stenting mechanism, depending on the status of the embolus and other therapeutic aspects of the treatment being offered for consideration.

  • Patent number: 8945172
    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.

  • Patent number: 8926680
    Abstract: Devices, methods and systems facilitate and enable vessel wall treatment, particularly at the neck of an aneurysm. A tethered cage-like structure functions in conjunction with supplemental therapies such as a vaso-occlusive coil delivering microcatheter system and/or pharmaceutical delivery, among other things, by stabilizing vessel walls and providing tethered cage-like therapeutic support for treating aneurysms, temporarily or on an implantable basis.

  • Patent number: 8790363
    Abstract: The three dimensional, low friction vasoocclusive coil has a portion that is three dimensionally box or cubed shaped. The three dimensional box or cubed shaped portion will form a basket for filling the anatomical cavity at the site in the vasculature to be treated. The vasoocclusive device is formed from at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter or cannula to a desired portion of the vasculature to be treated, and a second operable, three dimensional configuration for occluding the desired portion of the vasculature to be treated. The vasoocclusive coil may optionally include a portion that is substantially J-shaped or helically shaped, for filling and reinforcing the three dimensional portion.
