 I have very exciting news to tell you today. I'm Dr. George Nahas, Chief of Cardiology at Beaumont, Dearborn in Michigan. There is a technological shockwave balloons. It is the same technology as lithotripsy that we use to break stones in the kidneys. Well, now we have it mounted inside a catheter on a balloon catheter that we can insert inside the heart, in the vessels of the heart that have very heavy calcifications, a lot of calcium, where traditional devices cannot open the blockage. So let's say somebody has a blockage, have a lot of calcium in a blockage, which is usually the case now, and we put usual average balloon, the balloon cannot expand it. We have other devices to shave the calcium. Sometimes it works, sometimes it doesn't. So now we have one more device that we can go to when everything else fails called the Shockwave IVL. It's a very neat balloon just got approved by FDA. We have it right in our hospital at Beaumont, Dearborn, available to our operators to use to open blockages that are difficult to open otherwise. We have used it in a few patients now with 100% success rate and no complications, and the results are phenomenal where the vessel that we cannot expand, suddenly we apply the wave and it expands. How does it work? Well, it has ultrasound waves that penetrate the calcium and break it like an egg shell. You only have an boiled egg and you knock it and you break the shell into many pieces, stays in place, but broken. That's how it works. And then when it's broken like that, then we can put other balloons and we can expand it and we can put stent and keep it open. That has added a lot to the care of our patients, especially who have difficult lesions to treat as I described. So please keep that in mind and we'll be very happy to see you if you need us to. Thank you. Have a beautiful day.
