  • 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.
