Abstract
An imaging core, that is configured and arranged for insertion into a catheter, includes a mirror disposed at a distal end of a rotatable driveshaft; a motor coupled to the driveshaft and including a rotatable magnet and at least two magnetic field windings disposed around at least a portion of the magnet on a rigid slotted material; and at least one fixed transducer positioned between the motor and the rotatable mirror. The driveshaft extends through an aperture in the magnet to allow passage of the driveshaft through the at least one transducer to the rotatable mirror. At least one transducer conductor is electrically coupled to the at least one transducer and in electrical communication with the proximal end of the catheter. At least one motor conductor is electrically coupled to the magnetic field windings and in electrical communication with the proximal end of the catheter.
