  • SYSTEM AND METHOD FOR DELIVERING A CATHETER
    Publication number: 20210046283
    Abstract: A method of delivering a catheter to a location of interest in the vasculature, the method including positioning a self-expanding sheath within a lumen of the catheter; advancing the catheter and the self-expanding sheath in tandem over a guidewire; and distally moving a distal end of the self-expanding sheath out from the lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter, wherein when the self-expanding sheath is in the expanded state both the self-expanding sheath and the catheter are distally advanceable in tandem.

    Abstract: A venturi pump can provide suction through a catheter during an intravascular treatment. The venturi pump can have a supply port, exhaust port, and vacuum inlet such that a fluidic flow from the supply port to the exhaust port produces suction at the vacuum inlet due to the Venturi effect. A device or assembly can include the venturi pump, a flow regulator, and a sealable entrance sized to receive the catheter. The flow regulator can be manipulated to adjust suction through the vacuum inlet of the venturi pump. The device or assembly can have an exit and a passageway between the entrance and the exit to allow a pull wire, Intermediate Catheter, or other clot retrieval system elongated member to pass therethrough and be manipulated during the intravascular treatment.

  • EMBOLIC COIL DELIVERY SYSTEM WITH RETRACTABLE MECHANICAL RELEASE MECHANISM
    Publication number: 20210022748
    Abstract: An embolic implantation system configured to deliver an embolic implant intravascularly to a treatment site includes an elongated delivery tube to which the embolic implant is detachably attached by a flexible loop extending through a retaining ring or opening on the embolic implant and an elongated detachment member or pull wire extending through the delivery tube and flexible loop. The pull wire has a bump near its distal end that inhibits the pull wire from moving further distally when the bump presses distally against the flexible loop and/or retaining ring. The flexible loop and retaining ring thereby serve as a distal obstruction obstructing distal movement of the bump and thereby distal movement of the pull wire into the implant.

    Abstract: A device for capturing an obstruction in a vasculature can include a first elongated member, an expandable element, an invertible element, and a gap positioned between the expandable element and the invertible element sized to be placed across the obstruction. The expandable element and the invertible element can be positioned near the distal end of the first elongated member. The expandable element can expand from a collapsed delivery configuration to an expanded configuration. The invertible element can expand from a collapsed delivery configuration to an expanded configuration, and the invertible element can invert from the expanded configuration to an inverted configuration, thereby forming a pocket. The pocket can envelope at least a portion of the gap and can thereby capture an obstruction that is in the gap.

  • PULL WIRE DETACHMENT FOR INTRAVASCULAR DEVICES
    Publication number: 20200397444
    Abstract: An assembly at a proximal end of an intravascular delivery system can allow the proximal end of a pull wire to move independently of a delivery tube. The assembly can generally include the pull wire, the delivery tube, a feature to prevent the proximal end of the pull wire from becoming inaccessible due to distal movement of the pull wire, and a feature to protect the proximal end of the pull wire from inadvertent, premature manipulation. When the intravascular delivery system is navigating tortuous vasculature, the proximal end of the pull wire can move distally in relation to the proximal end of delivery tube, relieving stress on the distal end of the pull wire. The proximal end of the pull wire can be protected from inadvertent manipulation during delivery and made available for manipulation once the distal end of the delivery system is in place.

  • INTRAVASCULAR DEVICES WITH RADIOPAQUE BODY MARKERS
    Publication number: 20200390515
    Abstract: An intravascular treatment device is presented having an expandable frame made up of circular struts, straight struts, and bent struts forming a frame with circumference that varies over the length of the frame. Radiopaque markers can be positioned on the bent struts to indicate outer circumferences of the frame along the length of the frame. The device can be a stent or a clot retriever. If the device is a clot retriever, the proximal end of the expandable frame can be attached to a guide wire and the distal end of the expandable frame can be free to slide over the guide wire when the frame moves from a collapsed state to an expanded state and vice versa.
