    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: 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.

    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: 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.

    摘要: A catheter including a catheter body having a catheter lumen is disclosed. A manifold assembly is coupled with a proximal catheter portion. A manifold lumen extends through the manifold assembly and includes an assembly cavity extending around the proximal catheter portion. A fluid jet loop including fluid jet orfices along a tapered loop guide surface is coupled with a distal catheter portion. The catheter further includes a composite guide having a proximal guide insert and a distal guide. The proximal guide insert is positioned within the assembly cavity and includes a guide insert surface flush with a catheter body interior wall. The distal guide includes a tapered loop guide surface, and an intermediate guide surface of the catheter lumen is flushly engaged with a leading edge of the tapered loop guide surface, the distal guide continuously tapering inwardly and distally along the tapered loop guide surface.
