My Neuro said the Boston dbs system is more advanced than Medtronics with more sophisticated programming options in delivering current to the leads. Plus the Boston rechargeable battery life is up to 15 years and is round instead of square with a thinner profile. I believe the Boston dbs has been installed in over 200 patients. Her sales rep, who used to be with Medtronics, is now with Boston because of their superior dbs system. I have not talked with anyone who has this new system.
