  • Patent number: 9161765
    Abstract: A thrombectomy catheter deployment for operation of a thrombectomy catheter includes 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 has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement of disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator.

  • Patent number: 8491523
    Abstract: Methods of conducting thrombectomy procedures and deploying a thrombectomy catheter are disclosed. A thrombectomy procedure is conducted with a thrombectomy catheter deployment system. A drive unit configured to operate an infusion pump is provided. The drive unit is operable according to one or more operating modes. A preconnected and consolidated pump and catheter assembly configured for loading in the drive unit is also provided. The assembly is separate from the drive unit prior to loading. The infusion pump and a catheter of the assembly are in communication prior to loading. The assembly provides one or more digital instructions to the drive unit. The drive unit is operable according to the one or more operating modes referenced by the one or more digital instructions. The assembly is loaded into the drive unit, and the drive unit is engaged to the infusion pump for operation of the infusion pump.

  • Publication number: 20110208205
    Abstract: A thrombectomy catheter deployment system which greatly simplifies setup procedures and operation of a thrombectomy catheter includes 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 has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement or disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator. A bubble trap incorporated for effective debubbling of saline solution is closely coupled to an insert molded pump having an improved valve arrangement.

  • Patent number: 7951161
    Abstract: An atherectomy system having a variably exposed cutter wherein a distally located positionable tip closely associated with the cutter and a high pressure fluid jet emanator can be variably and angularly deployed about a hinge mechanism subsequent to entry into the vasculature. The fixed cutter slices or parts atheromatous material and/or thrombotic material from a blood vessel for interaction with high pressure jets to macerate, break up or otherwise reduce the materials for evacuation from the site.

  • Patent number: 7842010
    Abstract: A pneumatically-operated thrombectomy catheter deployment system having a plurality of components collectively acting as a drive unit, including a double-acting air cylinder, a reciprocating assembly including a positionable four-way valve, a high pressure pump, an effluent pump, a compressed air tank, and other closely related components. The double-acting air cylinder is reciprocatingly driven by the complement of the drive unit components to provide high pressure saline for use in the thrombectomy catheter and to exhaust effluent from the system. A plurality of preconnected components are connected to the drive unit including a thrombectomy catheter, a saline supply bag, an effluent collection bag, connection tubes, and other closely related components.

  • Patent number: 6875193
    Abstract: A rapid exchange fluid jet thrombectomy device for removal of thrombus or unwanted tissue debris from a vein, artery or the like. The device includes a semi-rigid intermediate tube between a proximal and a distal exhaust tube which accommodates a guidewire tube exit located along the catheter at less than one-half the length of the catheter measured from the catheter most distal point. Such a location of the guidewire is convenient for maneuvering and longitudinal advancement of the guidewire, as well as maneuvering and longitudinal advancement of the catheter by one practitioner.
