  • 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: 7226433
    Abstract: A thrombectomy catheter device having an improved hemostasis valve which is self-sealing and which functions as a one-way valve. The self-sealing hemostasis valve can be factory preset to automatically seal with or without the inclusion of a guidewire at a certain desired pressure or allowable leakage. Such sealing is automatic without the need to manually manipulate a hemostasis nut to obtain hemostasis. The thrombectomy catheter device can, without hemostasis nut adjustment, be positioned along and about a guidewire while yet maintaining suitable pressure for sustaining hemostasis at a preferred level. Certain embodiments of the thrombectomy catheter device having a self-sealing hemostasis valve include an adjustable hemostasis nut which can be manually tightened to restrict flow or guidewire movement or loosened to reduce friction on the guidewire and allow fluid to flow out if desired.
