Hello. I had a Boston Scientific wave runner put in at the end of December 2023. I had a laminectomy to have the paddle installed. I have two leads that run down to the battery pack. While the recovery from surgery wasn’t fun I’m very happy with the outcome. My pain/sciatica is significantly reduced. I also had success from the trial which is why I chose to go for the surgery. As others have said it can be programmed by reps and you may have to meet up to have more program choices set up.
