  • Publication number: 20070129679
    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.

  • Publication number: 20070073233
    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.
