<p>The invention provides a frictional torque limiter assembly for an imaging core spinning in a patient's body. The torque limiter assembly torsionally isolates the imaging core from a motor that spins the imaging core. An interference fit between a slitted drive tube and a spacer tube acts as a clutch that allows a spinning imaging probe to slow or stop relative to the motor until the motor is stopped, thereby preventing an unsafe condition.</p> |
