  • Publication number: 20200100804
    Abstract: A joint assembly for an endovascular device, comprising a shaft comprising a main body and an enlarged end, a proximal strut comprising a slot, wherein the slot engages the enlarged end of the shaft and a locking collar comprising a proximal face and a distal face, and at least partially covering the enlarged end of the shaft and the slot of the proximal strut, such that the locking collar constrains the proximal strut such that the proximal strut cannot disengage from the enlarged end of the shaft when the joint assembly and the clot retrieval device is under load.

  • Publication number: 20190328411
    Abstract: A system for assisting in the retrieval of a clot from a vessel. The system can include an outer catheter and an inner catheter disposed in a lumen of the outer catheter. The inner catheter can include a distal end, a proximal end, a distal segment, a proximal segment, and a lumen extending proximal of the distal end and terminating at a transfer port at the proximal end of the distal segment. A seal is located on the outer surface of the inner catheter distal of the transfer port, the seal capable of sealing against the lumen of the outer catheter so that aspiration applied through the outer catheter is configured to be transferred to the inner catheter.

  • Patent number: 10441301
    Abstract: A rapid exchange (RX) catheter may provide a proximal seal against a guide catheter inner lumen so that aspiration may be applied through a guide catheter. The catheter may include an exit port that defines a transfer port for aspiration and may enable minimal frictional engagement with the guide catheter proximal of the exit port. Aspiration can be applied to the lumen of the guide catheter and may be directed to and effective at the tip of the RX aspiration catheter. A tip of the RX catheter may facilitate aspiration and retrieval of the clot by expanding under load and can also partially or fully occlude the vessel.

  • Publication number: 20190167287
    Abstract: A clot capture catheter comprises an elongate tubular shaft having a proximal end, a distal end and an inflatable expansile member at the distal end. The expansile member is inflatable from a collapsed delivery configuration to an expanded configuration. In the expanded configuration, the expansile member extends to define a funnel shape having an enlarged distal clot entry mouth at the distal-most end of the catheter. In the expanded configuration, the expansile member may extend distally beyond the distalmost tip of the shaft. The expansile member may be integral with the distal tip of the catheter shaft.

  • Publication number: 20190000492
    Abstract: A clot removal device for removing clot from a body vessel comprising an expandable structure and an elongate member. The elongate member can have a proximal end and a distal end, the elongate member being connected to the expandable structure at its distal end. The expandable structure can have a constrained delivery configuration, an expanded clot engaging deployed configuration, and an at least partially constrained clot pinching configuration. At least a portion of the expandable structure can be configured to engage clot in the expanded deployed configuration and to pinch clot on movement from the deployed configuration to the clot pinching configuration.

  • Publication number: 20170105743
    Abstract: A catheter has an expansile tip that can be delivered in a constricted form. The increased tip diameter facilitates the aspiration and removal of large clot volumes by increasing the area of the catheter tip that applies aspiration to the clot. The tip comprises a support frame which can be cut from a metal or polymer tube, covered with a thin polymer sleeve 909 containing highly elastic properties. This construction provides good pushability and high compressive resistance. The cut pattern can contain axial connections of the support frame and ring members, which will provide a large level of axial support, lateral flexibility and hoop strength to withstand aspiration. The tip of the device can contain a section proximal of the highly flexible area that can expand to except clot. This potential to increase body diameter facilitates the retrieval of large volume clots while the construction of the catheter provides good column stiffness to avoid axial collapse and still maintain good flexibility.
