    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.

    摘要： A catheter assembly for an intravascular ultrasound system includes a catheter insertable into patient vasculature via a guidewire. A watertight imaging core is disposed in the distal end of the catheter. The imaging core includes a motor, at least one fixed transducer, and a signal redirection unit. The motor includes a magnet configured and arranged to rotate upon generation of a magnetic field by magnetic field windings. The signal redirection unit is coupled to the magnet such that rotation of the magnet causes a corresponding rotation of at least a portion of the signal redirection unit. The signal redirection unit includes a tilted mirror that redirects acoustic signals transmitted from the fixed transducer to patient tissue. At least one transducer conductor and at least one stator conductor are electrically coupled to the imaging core and in electrical communication with the proximal end of the catheter.

    摘要： A method of turning a medical device with the assistance of an externally applied magnetic field, in a direction with a component in a plane perpendicular to the direction of the externally applied magnetic field. The method includes applying first torque to the distal end of the medical device by creating magnetic moment at the distal end of the medical device, and applying a second torque to the distal end of the medical device. The second torque may be created by creating a second magnetic moment at the distal end of the device spaced from the first, by using an electrostrictive device, by using a stylette inserted into the device, by using a fluid-driven shaped tube, or otherwise.
