IMPROVED CATHETER

摘要

An improved catheter is provided. The catheter may include a deflectable member located at a distal end of the catheter. The deflectable member may comprise an ultrasound transducer array. In embodiments where the deflectable member includes an ultrasound transducer array, the ultrasound transducer array may be operable to image both when aligned with the catheter and when pivoted relative to the catheter. When pivoted relative to the catheter, the ultrasound transducer array may have a field of view distal to the distal end of the catheter. The ultrasound array may be interconnected to a motor to effectuate pivotal reciprocal motion of the ultrasound transducer array such that the catheter may be operable to produce real-time or near real-time three dimensional images.
