ABSTRACT:
A torque device for selectively gripping a medical guidewire. The device includes a housing, an actuator slidably mounted on the housing, and a resilient member biasing the actuator. A lumen dimensioned to receive the guidewire extends through the housing and actuator. The resilient member biases the actuator from a first position in which the lumen portions are aligned, toward a second position in which the lumen portions are misaligned. The actuator may include a catch that interferes with a stop of the housing to retain the actuator within the housing. The actuator may be oblong or otherwise shaped to maintain the lumen portions in substantial alignment in a longitudinal direction. Preferably, at least a portion of the lumen is teardrop-shaped in cross-section. The housing may include circumferentially or longitudinally extending ribs defining an outer grasping surface. Frusto-conical cavities may be defined at entry and exit ends of the lumen.
