With the advent of the FDA trial, we have a valve premade. So it is manufactured for us as a cylinder, sewn to a specific diameter and length, and we’re able to choose the size from an array based on what we see on a patient’s echocardiographic studies. We can change that when we get in there and take a look at the valve but typically we’ve decided based on the size of the patient and the findings on the echocardiogram what size valve will be implanted. The final measurement is made when we’re taking a look at the valve, and that’s kind of a luxury because before we had to be certain about the dimensions of the valve before we started the operation, really, because we didn’t want to build it once we had the heart open. Now, we can do the third step. We can look at the echo, we can look at the patient, and we can look at the valve itself and make a decision then and there, take it off the shelf, and implant it a few minutes later.
