I cannot address RickH's questions directly, but I can offer a patient's perspective of the benefits of Dr. Cole's power extraction device. The following comes from a post I made in the main forum...
I am a patient of Dr Cole's who had a CIT procedure done 2 years ago (November 2009), and a second procedure done 2 days ago. In 2009 Dr. Cole was not yet using his PCID device, but rather punching each follicular group manually with a standard FUE punch. This week however he used the PCID device for my procedure. From my perspective, there are 2 significant differences:
1) Increased Comfort - Even though you are heavily numbed in the donor site areas, a standard FUE punch still creates a noticeable amount of pressure and it can jostle your head a little bit. That can be aggravating after a full day of punching. The PCID device however is smooth as silk and you can't feel the punching at all. No pressure, no jostling! Simply awesome.
2) SPEED - The PCID allowed Dr. Cole to work MUCH faster. To give you an idea just how much faster, in 2009 I had ~2000 grafts done, and it was a two day visit. This week I again had ~2000 grafts done, and it only took one day. That's huge! Anything that leads to less time in the chair is a huge bonus for the patient!
