Intelect has nothing released to the market, no clinical studies that could release anything. They may have a decent programming system that could be used with existing DBS implant procedures ("Guide"). Basically, this is $60 million of intellectual property. It's really a non-issue in the marketplace. St Jude and BSX need to complete their DBS clinical studies to get approval - even in a best case scenario that will take over 2 years with everything going perfect.
Then they'll be fighting in a market with extremely low unit volumes. But it will definitely be growing at 10% per year, so even if they are stealing only part of the growth from Medtronic, they could do OK. It looks like the clinical studies are so expensive that there isn't really a chance of anyone other than BSX and STJ funding them.
