You might call Pari and ask them if they replaced the Pari Vios Pro with the Pro Neb Max. If you google Pari Vios pro it does bring up some for sale but Pari may have replaced it with the newer model and your Dr does not know. The Pari Vios Pro is blue and the Pro Neb Max is white. The Pari Vios is green. LC Sprint and LIC Plus are two different types of cups and you can use either one. I think the Plus is slower. I tried both and personally prefer the Sprint. Get one of each and see what works the best for you.
