摘要： An imaging assembly for an intravascular ultrasound system includes a catheter, an imaging core, and at least one transducer conductor. The imaging core is insertable into the catheter and extendable from a distal end of the catheter. The imaging core includes a rotatable magnet, a tilted reflective surface, and at least one fixed transducer all disposed in a body. The rotatable magnet is configured and arranged to rotate by a magnetic field generated external to the catheter. The tilted reflective surface rotates with the magnet. The at least one transducer is configured and arranged for transforming applied electrical signals to acoustic signals and also for transforming received echo signals to electrical signals. The at least one transducer conductor is electrically coupled to the at least one transducer and is configured and arranged to extend into the catheter when the imaging core is extended from the catheter.

摘要： Intravascular nerve modulation systems and methods for making and using the same are disclosed. An example system may include an elongate shaft having a proximal end region and a distal end region and a central longitudinal axis. An ablation transducer may be disposed at the distal end region. The system may also include a rotational drive configured to rotate the ablation transducer about the central longitudinal axis. A control and power system may be operably connected to the ablation transducer and the rotational drive. In some instances, the ablation transducer may be a combined ablation and imaging transducer.

摘要： A catheter assembly for an intravascular ultrasound system includes an imaging core disposed in a lumen of a catheter. The imaging core includes a stepper motor that rotates a mirror coupled to a driveshaft. The stepper motor provides step-wise rotation of the driveshaft using a rotatabSe magnet and at least two magnetic field windings disposed around at least a portion of the magnet. At least one fixed transducer is positioned between the stepper motor and the mirror. The stepper motor permits stepwise rotation of the driveshaft with steps of 3 degrees or less. At least one transducer conductor is electrically coupled to the at least one transducer and in electrical communication with a 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.
