SYSTEM OF CATHETER FOR IMAGE GUIDE

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic imaging catheter for guiding the heart treatment.SOLUTION: A catheter-mounted imaging system comprises a catheter 1000. The catheter comprises: a nested 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 comprises a patient interface module 2000. The patient interface module comprises: a catheter interface 2100; a rotational motion control system which gives controlled rotation to the ultrasonic imaging core; a linear translation control system which gives controlled linear translation to the ultrasonic imaging core; and an ultrasonic energy generator and receiver which are coupled to the ultrasonic imaging core. The system further comprises an image generator which is coupled to the ultrasonic energy receiver and generates an image.SELECTED DRAWING: Figure 1
