ABSTRACT:
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.
