Abstract
A torque device for attaching to and selectively gripping and releasing a catheter guidewire to permit rotational and longitudinal manipulation of the guidewire to steer the guidewire through a vessel. A spindle is threadably engaged in a cap, and a bore through the spindle aligns with a bore through the cap to accept the guidewire. The end of the spindle inside the cap has a pair of fingers straddling the guidewire. As the cap and spindle are rotated with respect to each other, the threaded engagement of the spindle and cap forces the end of the fingers to advance along a tapering bore in the cap, which causes the fingers to close and grip the guidewire. Reversing the direction of rotation releases the grip on the guidewire.
