Abstract:
An apparatus for providing, in combination, a hemostasis valve, a steering device for an intravascular instrument such as guidewire, and a fluid coupling device for attachment to a fluid delivery system, comprising:means for providing a single, straight passageway through which either an intravascular instrument or fluids are introduced, as selected; means, disposed within said passageway, for selectively sealing and unsealing said passageway in response to a compressive force exerted on said means for selectively sealing and unsealing said passageway, the means for selectively sealing and unsealing said passageway assuming a normally open position when not subjected to said compressive force, and responding to said compressive force so as to selectively and progressively reduce the size of said passageway; and a single means for both (i) selectively increasing and decreasing said compressive force, and (ii) rotatable attachment of said passageway to a fluid delivery system.
