    摘要: An instrument for use in catheterization of small distal branch arteries includes a guide wire having a short flexible distal section connected with a relatively long, multi-wire, axial and rotary torque transmitting section to guide a soft, thin-walled, flexible catheter through the compound curves involved in the junctions between various arterial branches. A method for catheterization of blood vessels includes the steps of sequentially advancing the catheter and guide wire to negotiate these compound turns in the arterial system.

    摘要: A guide wire capable of being adjusted to provide variable stiffness for catheterizing arterial branches comprises an elongated helical wire coil with a plurality of core wires contained within and joined to the outer wire coil at their distal ends; at their proximal ends there is a handle having two elements which are movable relative to each other connected respectively to the inner core wires and to the wire coil to vary the extent to which the coil may be flexed, by tensioning the core wires and limiting the longitudinal expansion of the coil.
