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.

Direct stream hydrodynamic catheter system

An annular seal for sealing an opening in a pump housing surrounding a piston rod includes a primary sealing portion with an inner surface adjacent to the piston rod and an outer surface adjacent to the pump housing. An initial sealing portion features an inner wall and an outer wall so that an annular space is defined therebetween. A top wall extends between the inner and outer walls. A coil spring is positioned within the annular space of the initial sealing portion and urges the inner wall into engagement with the piston rod and the outer wall into engagement with the pump housing.

Pump seal

A system for dispensing a cryogenic fluid includes a bulk storage tank configured to contain a supply of the cryogenic fluid. A heat exchanger coil is positioned in the headspace of at least one intermediate fluid tank, which contains an intermediate fluid, and is configured to receive and warm a cryogenic fluid from the bulk storage tank via heat exchange with intermediate fluid vapor in the headspace. A buffer tank receives fluid from the heat exchanger coil. A chiller coil is positioned within the intermediate fluid tank and is submerged within intermediate fluid liquid contained within the at least one intermediate fluid tank. The chiller coil receives fluid from the buffer tank and cools it via heat exchange with intermediate fluid liquid within which the chiller coil is submerged for dispensing.

Cryogenic fluid dispensing system having a chilling reservoir

A catheter including at least one distal opening positioned at or near the distal end and at least one proximal opening near the proximal end and proximal to the at least one distal opening is described. The catheter may be configured for delivering at least a first fluid through the at least one distal opening to a central circulation system of a patient and delivering at least a second fluid through the at least one proximal opening to a peripheral circulation system of the patient.

Catheters and related equipment

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.

Intravascular guidewire filter system for pulmonary embolism protection and embolism removal or maceration

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.

Enhanced cross stream mechanical thrombectomy catheter

A catheter assembly includes a catheter body having a catheter lumen. A manifold assembly is coupled with a proximal catheter portion. A manifold lumen extends through the manifold assembly, and the manifold lumen includes an assembly cavity extending around the proximal catheter portion. A fluid jet loop is coupled with a high pressure tube at a distal catheter portion. The catheter assembly further includes a tapered loop guide surface.

Catheter having tapered guide surface

A thrombectomy catheter deployment for operation of a thrombectomy catheter may include a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

Thrombectomy catheter deployment system

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.
