  • Patent number: 10799669
    Abstract: A rapid exchange microcatheter for accessing the intracranial neurovasculature. A side opening through the sidewall is located a first distance proximal to the distal-most tip. A proximal opening located proximal to the side opening is a second distance from the distal-most tip. A distal, reinforced catheter portion extends between a distal end region to a point near the side opening. A proximal, reinforced catheter portion extends a distance from a point near the side opening towards the proximal end of the catheter body. The side opening is positioned within a gap between a proximal end of the distal reinforced catheter portion and a distal end of the proximal reinforced catheter portion. A payload of a cerebral treatment device is housed within the lumen proximal to the side opening. Related devices, systems, and methods are disclosed.

  • Patent number: 10779855
    Abstract: An arterial access device has an internal lumen and a proximal port, the arterial access device sized and shaped to be inserted directly into an arterial access site in the common carotid artery such that the lumen provides a passageway for an interventional device to be inserted via the proximal port into the carotid artery. The arterial access device has a distal portion that is configured to be inserted into an arterial pathway through the access site, and a proximal portion configured to extend outward from the access site when the distal portion is in the arterial pathway.

  • Patent number: 10743893
    Abstract: Described are methods and systems for transcervical access of the cerebral arterial vasculature and treatment of cerebral occlusions, including ischemic stroke. The methods and devices may include methods and devices which may provide aspiration and passive flow reversal, those which protect the cerebral penumbra during the procedure to minimize injury to brain, as well as distal catheters and devices to remove an occlusion. The methods and devices that provide passive flow reversal may also offer to the user a degree of flow control. Devices and methods which provide a way to securely close the access site in the carotid artery to avoid the potentially devastating consequences of a transcervical hematoma are also described.

  • Patent number: 10722251
    Abstract: Described are systems for performing a medical procedure at a treatment site in a cerebral vessel of a patient. The system includes a catheter and an inner member sized to slide within the catheter lumen. The inner member defines a single lumen and has a distal portion and a distal-most end having a distal opening, the distal portion having a first outer diameter that tapers distally to a second outer diameter that is smaller than the first outer diameter. A flexibility of the distal portion decreases smoothly from a flexibility at the second outer diameter to a flexibility at the first outer diameter when the system is in an advancement configuration. The system is sufficiently flexible that, when in the advancement configuration, the system is configured to be advanced distal to a petrous portion of an internal carotid artery.
