I think what Rush has provided to us is the ideal platform of having incredible imaging. So we can see the blood vessels very well, and we can see what we are doing during surgery. So having that technology has just been a revolution.
The key though, at the end of the day, is to have that goal of — you have your technology. You have your options. But it’s how you pick which tools you’re going to use to maximize that efficiency of treatment, but also the ability to minimize the impact of quality of life of the patient, so that they can come in with a very significant medical problem — such as a brain aneurysm, vascular malformation or blockage of a blood vessel in the head, like a stroke for example — and be able to get out of this experience, have your disease treated, cured from that, and return to your life in a short period of time. I think it’s an amazing goal, and that’s what we strive for.
