CONTROLLING AND VISUALIZING ROTATION AND DEFLECTION OF A 4D ULTRASOUND CATHETER HAVING MULTIPLE SHAFTS

CONTROLLING AND VISUALIZING ROTATION AND DEFLECTION OF A 4D ULTRASOUND CATHETER HAVING MULTIPLE SHAFTS

A catheter includes: a shaft for insertion into an organ of a patient, and first and second position sensors. The shaft includes: (a) an inner shaft, which is configured to be deflected relative to an axis of the shaft, and (b) an outer shaft, which is coupled to a distal tip of the catheter and is...

Zusammenfassung:A catheter includes: a shaft for insertion into an organ of a patient, and first and second position sensors. The shaft includes: (a) an inner shaft, which is configured to be deflected relative to an axis of the shaft, and (b) an outer shaft, which is coupled to a distal tip of the catheter and is configured to be: (i) coaxially disposed around the inner shaft, (ii) deflected together with the inner shaft, and (iii) rotated about the axis relative to the inner shaft. The first position sensor is coupled to the distal tip and is configured to produce a first signal, and the second position sensor is coupled to the inner shaft, and is configured to produce a second signal.
