  • Publication number: 20190290315
    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: 9943397
    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.

  • 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.

  • Patent number: 9149609
    Abstract: The general purpose of the present invention is to provide a catheter for removal of an organized embolic thrombus, preferably in conjunction with a distal occlusion balloon guidewire. The present invention consists of three main components including a capture/delivery sheath, a capture sleeve of mesh attached to a tube and a grasping mechanism attached to another tube which is central to the other components. Operative structures in the form of manifolds are connected to such components in order to manipulate and control the relative positions of the capture/delivery sheath, the capture sleeve and the grasping mechanism. An embolic thrombus is engaged by the deployable automatically expanding serrated fingers of a grasping mechanism in combination with a deployable automatically expanding mesh capture sleeve. The capture/delivery sheath is maneuvered to cause compression of the serrated fingers and of the mesh capture sleeve for subsequent removal of the embolic thrombus.

  • Patent number: 9078691
    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example catheter is disclosed. The catheter comprises a catheter body having a catheter lumen and a high pressure tube disposed within the catheter lumen. The high pressure tube has a substantially circular cross section. The catheter also includes a fluid jet loop coupled to the high pressure tube at a transition section. The transition section has a circular cross section and a non-circular cross section. The fluid jet loop includes fluid jet orifices along a tapered loop guide surface. The catheter also includes a distal guide. The intermediate guide surface of the catheter lumen flushly engages with a leading edge of the tapered loop guide surface and the distal guide is configured to guide the instrument over the intermediate guide surface, the tapered loop guide surface and through the fluid jet loop.

  • Publication number: 20150173790
    Abstract: The present invention provides a forwardly directed fluid jet crossing catheter having a distally directed cylindrical flow fluid jet stream to cross a chronic total occlusion. The distal end of the device includes a formable catheter tip region having flexible internal components. Low and high pressure cavities are formed substantially by joined proximal and distal catheter tubes having an adhesive plug seal in common therebetween which partially defines one end of each of the low pressure and high pressure cavities. A guidewire tube and a high pressure tube are aligned along and within the low pressure and high pressure cavities and through the adhesive plug seal. The high pressure tube openly terminates in the high pressure cavity, whereby pressurized fluid transfers from the high pressure cavity in the guidewire tube entry hole to subsequently pass along the guidewire lumen and co-located guidewire to exit as a cylindrical fluid jet stream.
