    摘要: An intravascular catheter having a flow diffusing distal tip includes a plurality of cuts formed through the tubular wall thereof so as to define a plurality of generally U-shaped flaps, the flaps being disposed in at least one and preferably two axially displaced bands. When contrast fluid or the like is injected under pressure into the proximal end of the catheter, the flow of the liquid exits the openings in which the plurality of flaps are hinged, causing the flaps to vibrate and effectively eliminate any tendency for the contrast media to be expelled as a jet from the open distal end of the catheter. Having an open distal end allows the catheter to be passed over a guidewire.

    摘要: A hemostasis valve including a collapsible membrane in a portion of a through-lumen. Fluid pressure in a chamber surrounding the collapsible membrane assists in sealing the collapsible membrane around an operating device inserted through the hemostasis valve. Different mechanisms for mechanically deforming the collapsible membrane to assist in sealing are disclosed. Also, a system for continuously flushing a vascular catheter connected to a hemostasis valve at a rate of 0.10 to 10.0 cubic centimeters per minute, and a hemostasis valve assembly including an expandable reservoir which stores liquid volume under pressure.

    摘要: An apparatus for flushing a vascular catheter. Inlet and outlet passages extending from inlet and outlet ports, respectively, are selectably in communication with one another via a manually operable member cooperating with a sealing member and biased toward a closed position. Mechanisms for continuously and periodically flushing the catheter are incorporated.
