Joan I have had this surgery too, 3 years ago as an experimental research at Oregon Health Science University. Since I wrote my story for the web page I have been told that it is a STN DBS. Recently my battery died and I feared paying the $12,000 for a new one but my insurance has agreed to pay for the replacement. It has been replaced but it still isn't adjusted as well as the first one. It took almost 2 years to get the best adjustment. After you read my web page (address at the end of this email) feel free to ask me any questions. >Janet, > >Thanks for the abstract. It was quite reassuring.
