Approximate geometry of the modified microlinear-PZT catheter tip. The original microlinear-PZT tip has a special metal coated plastic which is transparent to ultrasound but permits simultaneous RF ablation. Experimental temperature feedback is performed with placement of a very small (<100 µm) thermocouple (arrow) in the plastic tip housing.
