Yeah, maybe Iâll take the second question first. So we will keep people updated on the progress as to how thatâs going. We were recently at RBCâs facility where they presented the finished prototypes to us, and then incorporated our electrode and our accessories to actually do benchtop testing. And these tests are done in egg-whites; itâs the traditional way of testing them. And what you do is, when youâre connected to the generator that creates the ablation, you put the electrode in the solution, and you initiate the device, you initiate ablation. And what you see is a nice lesion, which is basically egg-whites in a beaker. Thatâs the way we did the test when we started this project years ago at the Cleveland Clinic. And but this was the first time we had finished prototypes of really the software and hardware as well as all the accessories and electrodes, and it really performed very, very well. In fact, I was expecting â I wasnât expecting it to perform as well as it did. But, Iâm thankful it did. So what type of testing are we going to be doing from here, weâve already done animal testing, not with the actual finished prototype. But we have pieced together a system to demonstrate that it worked at Emory University a month ago. Weâre going to be redoing animal studies, as a way of making sure everything is still performing the way it needs to. We have an idea of what type of testing we need for FDA submission. Weâve already worked with consultants to determine that. And the determination has been that it doesnât have to be in live animals. But it will be an animal study. And again, what youâre looking to do is demonstrate that you can create a lesion within a certain specified range that you want, as well as obviously safety data that youâre not harming, the device itself isnât causing harm to the animal. So thatâs what we expect to be doing. And then what the other piece that weâre waiting on is components, final components, which are on order, donât expect them in for another couple of months. Now, this is more of the fun that everybodyâs experienced with supply chain delays. But the good news here is that, weâre building the units for design verification, final testing, and then submission to FDA. And thatâs kind of how weâve come to our timeline. But the really hard work in terms of development, we feel very good is behind us. Itâs now fine-tuning things, making sure the software is working, the way it need to thereâs no glitches. So, I would say, itâs more fine-tuning then development thatâs left with the project.
