ABSTRACT:
The present invention provides for catheter systems and methods of their use. In one embodiment, the invention provides a catheter comprising a catheter body having a proximal end, a distal end and a working lumen. A drive cable is disposed within the lumen and at least one transducer is attached to the cable near the distal end. A rotary transformer is included, comprising a transformer stator which is spaced apart from a transformer rotor. The rotor is operably attached to the cable to rotate therewith. The rotor is electrically coupled to the transducer and is magnetically coupled to the stator to allow a signal to be transmitted from the transducer to the stator during rotation of the cable.
