  • Publication number: 20240285389
    Abstract: An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.

  • Publication number: 20230031241
    Abstract: A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled powered direct fluid jet streams emanate from a fluid jet emanatory in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus and lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.

  • Patent number: 10314609
    Abstract: A thrombectomy catheter includes a catheter body having a catheter lumen. An outflow orifice is positioned along a catheter perimeter. A fluid jet emanator communicates with a high pressure tube. The fluid jet emanator includes at least one jet orifice for directing a fluid jet from the fluid jet emanator through the catheter lumen toward the outflow orifice. The fluid jet emanator provides a jet stream from the catheter body through the outflow orifice. The jet stream includes first and second stream portions. An entrainment fluid flow circuit includes at least the first stream portion, and the entrainment fluid flow circuit entrains particulate and macerates the particulate therein. An exhaust fluid flow path includes the second stream portion, and the exhaust fluid flow path draws entrained particulate from the entrainment fluid flow circuit at a location exterior to the catheter body and directs it toward the catheter proximal portion.

  • Patent number: 9585686
    Abstract: An infusion flow guidewire and a system including an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip having a closed distal end, a coil, a core wire and at least one distally located rearwardly directed jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided in the system for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.

  • Patent number: 9238119
    Abstract: Fluid infusion systems and fluid couplings are described herein. The infusion systems may include one or more fluid couplings used to make fluidic connection between a supply line and delivery tubing. The fluid couplings separate the functions of providing a seal around a delivery tube and retaining the delivery tube within the fluid coupling. The seal provided around the delivery tube prevents leakage around an exterior surface of a delivery tube such that fluid passing through the coupling must pass through the delivery tube rather than leak around the delivery tube. The structure used to retain the delivery tube in the fluid coupling prevents ejection of the delivery tube from the coupling due to the fluid pressures present in the coupling. The separate functions are performed by different structures within the fluid couplings.
