SYSTEM AND CATHETER FOR IMAGE GUIDANCE AND METHODS THEREOF
First Claim
1. A catheter-based imaging system, comprising:
- a catheter having a telescoping proximal end, a distal end having a distal sheath and a distal lumen, a working lumen, and an ultrasonic imaging core, the ultrasonic imaging core being arranged for rotation and linear translation;
a patient interface module including a catheter interface, a rotational motion control system that imparts controlled rotation to the ultrasonic imaging core, a linear translation control system that imparts controlled linear translation to the ultrasonic imaging core, and an ultrasonic energy generator and receiver coupled to the ultrasonic imaging core; and
an image generator coupled to the ultrasonic energy receiver that generates an image.

Abstract
A catheter-based imaging system comprises a catheter having a telescoping proximal end, a distal end having a distal sheath and a distal lumen, a working lumen, and an ultrasonic imaging core. The ultrasonic imaging core is arranged for rotation and linear translation. The system further includes a patient interface module including a catheter interface, a rotational motion control system that imparts controlled rotation to the ultrasonic imaging core, a linear translation control system that imparts controlled linear translation to the ultrasonic imaging core, and an ultrasonic energy generator and receiver coupled to the ultrasonic imaging core. The system further comprises an image generator coupled to the ultrasonic energy receiver that generates an image.
