Question-and-Answer Session
Operator
(Operator Instructions). Our first question is from Amit Bhalla with Citi.
Amit Bhalla - Citi
Hi, good morning.
Emile Geisenheimer
Good morning.
Amit Bhalla - Citi
I wanted to just to start with the performance of the disposables business, and hoping, Guy you could tease out what portion came from unit growth versus pricing growth. And then maybe just explain why coronary is all of the sudden growing, and I have a follow-up.
Guy Childs
Sure.
Emile Geisenheimer
Guy will cover the first part of that, and I think I'll cover the coronaries.
Guy Childs
Amit, we did have a price component to the growth this quarter. It ranged from 3% to 5%. 3% primarily on the fiber based catheters, and 5% on the non-fiber based. But, still most of the growth was unit-driven.
Amit Bhalla - Citi
Okay. With respect to coronaries, our device is particularly effective in dealing with thrombus and you may recall that in our PMA label, we have an individualization of use for treatment of acute thrombus AMI and low injection low injection fraction.
The number of physicians have become very interested in this area and are using the device for those kinds of applications and that has led to increasing interest in fixing of coronary catheters.
Amit Bhalla - Citi
Is there a increased selling focus in coronary, and I have a question for Jason Hein, if you can maybe address what the belief is on how the Heart Rhythm Society guidelines for Lead Management is going to change next week?
Guy Childs
Amit, I can answer the coronary training fees. Certainly there is a big focus from our sales organization to reestablish our training programs as it relates to coronary and the objective here is really to get more physicians involved, get them trained and as I think what's actually been most effective for us, is actually having the sales representative be with the physician when he goes through this training, so that there is plenty of follow-up post training as well, so it has been very effective for us.
Jason Hein
Yeah, Amit. This is Jason. As far as the HRS guidelines, obviously those guidelines won't be rolled out until Thursday evening. But at a high level, we expect there has been a lot of discussion around training a physician in indications. So we expect those to be two major components in the new revised guidelines. But again, definitely expect to see a lot more in next week.
