Hi All, I have a Medtronics Model 37712 Spinal Cord Stimulator that I can't charge. It has now died and I have to have it removed. The surgeon who did the implantation won't take my calls and I had to write to the CEO of Medtronics to get a response from them. Has anyone else with a similar device had the charging problem. If so what were you able to do about it. I would appreciate all any advice. Thanks
