Patent ID: 7077808

Claim:
An ultrasonic imaging catheter apparatus comprising: a flexible elongate body adapted for insertion into a body lumen, the elongate body having distal and proximal ends; an ultrasonic transducer disposed proximate said distal end of said elongate body, said ultrasonic transducer generating and detecting ultrasonic energy; a reflective member proximate said ultrasonic transducer, said reflective member being adapted to reflect (a) ultrasonic energy generated by said ultrasonic transducer to a wall of said body lumen and (b) ultrasonic energy reflected by said wail back to said transducer; and an actuator in mechanical communication with said reflective member, said actuator being adapted to change the angle of incidence of said ultrasonic energy relative to said reflective member, wherein control signals for said ultrasonic transducer and for said actuator are transmitted via a common electrical conductor.
