SYSTEMS AND METHODS FOR MAKING AND USING A MOTOR DISTALLY-POSITIONED WITHIN A CATHETER OF AN INTRAVASCULAR ULTRASOUND IMAGING SYSTEM
摘要
A catheter assembly for an intravascular ultrasound system includes an imaging core configured and arranged for inserting into a distal end of a lumen of a catheter. The imaging core includes at least one transducer mounted to a driveshaft and configured and arranged for transforming applied electrical signals to acoustic signals and also for transforming received echo signals to electrical signals. A motor is coupled to the driveshaft between the one or more transducers and the transformer. The motor includes a rotatable magnet and at least two magnetic field windings disposed around at least a portion of the magnet.
