    摘要: 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 high powered direct fluid jet streams emanate from a fluid jet emanator in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus or 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.

    摘要: A thrombectomy catheter with a self-inflating proximal balloon having drug infusion capabilities is described. A self-inflating balloon is formed from an inflatable thin walled section of a flexible catheter tube. The self-inflating balloon includes a plurality of outflow orifices located about the peripheral circumference thereof and located proximal to an inflow gap interposed between a fluid jet emanator and the self-inflating balloon. The self-inflating balloon is inflated and expanded by internal operating pressures by proximal composite flow of fluid from the fluid jet emanator and entrained fluid from the inflow gap to uniformly space and position the outflow orifices of the self-inflating balloon in close proximity to the thrombus or vessel walls of a blood vessel. The thrombectomy catheter may be used for, among other things, thrombectomies, embolectomies, thrombus or vessel dilation, and for the delivery of drugs to a thrombus or vessel site.

    摘要: The devices of the present disclosure are rheolytic thrombectomy catheters with a self-inflating distal balloon. A self-inflating balloon is located distal to an inflow gap or orifice and distal to a fluid jet emanator, which self-inflating balloon is inflated and expanded by the utilization of internal operating forces consisting of forwardly directed high velocity fluid jet streams and/or entrained thrombus particulate therein. The self-inflating balloon, when inflated, impinges on the wall of the blood vessel to isolate sections of the blood vessel distal and proximal to the inflated balloon in order to prevent flow of thrombus particulate, fluids and the like distal to the self-inflating balloon and to provide a stagnant nonflow region proximal to the self-inflating balloon. The devices of the present disclosure also provide for a uniform spacing of the catheter tube with respect to the thrombus and/or wall of the blood vessel.

    摘要: A forwardly directable fluid jet crossing catheter having a positionable jet body which can be longitudinally and rotationally positioned in order to direct a fluid jet stream to impinge, break through, and cross a chronic total occlusion. The distal end of the catheter includes a tip of super-elastic material having a flexible bend aligned within the distal portion of a sheath which tip is directable in response to the longitudinal and rotational orientation of a positionable jet body, whereby a fluid jet stream can be controlled in angular and rotational directions.

    摘要: An enhanced cross stream mechanical thrombectomy catheter having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. A multidirectional fluid jet emanator positioned within the distal catheter lumen comprises high velocity fluid jets which produce jet flow that is directed toward distal and proximal ends of the catheter. Jet flow directed toward the proximal end provides a region of low pressure near an inflow orifice which acts to pull thrombotic particulate from the vasculature. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from one side of the catheter distal end urges the opposing non-orificed side of the catheter distal end toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall.

    摘要: An enhanced cross stream mechanical thrombectomy catheter with backloading manifold having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from the one side of the distal end of the catheter resultantly urges the distal end of the catheter and thus the opposing non-orificed side of the distal end of the catheter toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall. Features of the invention include a geometrically configured insert to facilitate the backloading or exchange of guidewires.
