  • Patent number: 10881496
    Abstract: Various devices are described to provide filtering of flow from the aorta to the left carotid artery and the right carotid artery. The filters can be brought into a desired position through one or more peripheral arteries. A single filter device can provide the desired filtering or a plurality of devices can be used. In particular a single filter device can span between the brachiocephalic artery and the left carotid artery. These filter devices can be used effectively to capture emboli generated during procedures on the heart so that emboli do not travel to the patient's brain where the emboli can cause a stroke or other adverse event. In particular, these filters can be used during percutaneous procedures on the heart, such as endovascular heart valve replacement.

  • Publication number: 20200276411
    Abstract: A suction catheter system is described with a suction nozzle that can extend from a guide catheter of the like. The suction nozzle can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. A suction lumen extends from the proximal end of the guide catheter through at least part of the guide catheter central lumen and through the suction tip. Desirable suction flow can be established using the guide lumen to facilitate the suction. Also, a delivery catheter is described with an elastic tip that can track closely over a guidewire. The elastic tip of the delivery catheter can be expanded to provide for the delivery of medical devices past the tip.

  • Patent number: 10682217
    Abstract: Filtration systems with integrated filter element(s) forming portions of the wall of the filtration catheter are disclosed. The filtration catheters disclosed herein are designed to be used alone or in conjunction with another filter device to provide embolic protection of both carotid arteries. Occlusive element such as balloon is placed on the exterior of the filtration catheter to redirect blood flow in the vessels during the filtration process as well as to help anchor the filtration catheter inside the vessel. The integrated filter element(s) does not require collapsing thus significantly reduces the complexity of the filtration system retrieval process and the chances of releasing emboli back into the blood stream. The compact design of the filtration systems makes them particularly suitable for embolic protection during endovascular procedures on or close to the heart.

  • Publication number: 20200101267
    Abstract: Three groups of guidewire embodiments are described with particularly suitable structures for navigating circuitous vessels, especially blood vessels of the brain. Some of the guidewires have a hyperbolic taper that provides desired flexibility. In some embodiments, an integrated guide structure provides for extension in the blood vessel of a corewire to provide for extended reach of the guidewire. In further embodiments, the guidewire has a flexible tip that can be guided directly by the flow in the vessel.

  • Publication number: 20200046389
    Abstract: Clot engagement element comprising bundle of unwoven fibers can be assembled to form an acute stroke treatment device. The device has the capability of forming a three dimensional filtration matrix comprising effective pores with a distribution of sizes. The bundle of fiber design allows the device to be effectively delivered into circuitous cerebral arteries to remove clot that causes stroke. The fiber bundle based filtration matrix offers the advantages of conforming to the changing inner perimeter of a blood vessel during a clot removal process and thus the capability to effectively retain and remove a clot in the vessel. The filtration matrix offers the additional advantage to trap any break-off of the clot during the removal process. A plurality of fiber bundles can be combined to form an effective clot engagement element. Supplemental engagement structure as well as mechanical treatment structure can be integrated into the stroke treatment device.

Designs of stent retrievers are presented with polymer covers or mounted on the exterior of a microcatheter. Corresponding systems are described that can use various combinations of the components, generally in combination with an aspiration catheter. Corresponding procedures are described that can effectively use the various devices and systems.

  • Publication number: 20190381221
    Abstract: A suction catheter system is described with a suction extension interfaced with a guide catheter to form a continuous suction lumen extending through a portion of the guide catheter and through the suction extension. The suction extension can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. The suction extension can comprise a connecting section with a non-circular cross section for interfacing with the inner lumen of an engagement section of the guide catheter. The tubular body of the guide catheter can have a reduced diameter distal section the can be useful to restrain the movement of the suction extension.

  • Publication number: 20180098778
    Abstract: Clot removal from a patient's vessel, such as an artery, are described using aspiration and hydraulic forces supporting the removal process. Hydraulic forces can be generated by occluding the vessel distal to the clot and delivering liquid between the clot and the occlusive device. The aspiration catheter is positioned proximal to the clot. Catheters designed to facilitate the delivery of hydraulic forces can be based on single lumen designs or dual lumen designs. The catheters may have a fixed internal wire, or in some embodiments the catheters can ride over a wire with a valve/seal positioned to restrict flow into or out from the guide lumen such that the guide lumen can further function for balloon inflation and/or for infusion of liquid.
