Abstract
Guidewire insertion method and apparatus. A guidewire can be inserted into an obstructed blood vessel. A proximal portion of the guidewire is driven back and forth at high speed by a hand-held drive unit containing a battery, a D.C. motor and a transmission that converts rotating motor output shaft motion to reciprocating back and forth movement of a clamp that engages the guidewire. The guidewire moves back and forth at high speed within a catheter and a distal guidewire tip engages the obstruction with a ramming back and forth action to form a pilot passageway through the obstruction.
