Just saw your comment. Hopefully someone will benefit from what I write. I have had an intrathecal pain pump since 2005 and currently on my 5th pump. Four of the pumps have been Medtronic and one was a Flonic intrathecal pain pump. Sadly the Flonic pump malfunctioned after 4 weeks and had to quickly be removed. The Dr that implanted the flonic pump said that programming each month was a nightmare requiring much time. I get my pump filled 1 time a month and has a mixture of 4 different pain meds, i.e., fentanyl, morphine, baclifin, colonidine and puvicane. Sorry about the mistakes in spelling of the meds. Before you make a decision about a pump know this, it WILL NOT take away all your pain, it will help you to deal with it better. You have to change your lifestyle by eating better, losing weight, exercise, boy I sound like a dr here, I'm not. Yes I have had the catheter block twice and be replaced. I overdosed twice because of the pumps but think of this, your not taking any oral pain meds anymore. I also have a medtronic pain stimulator as well and on my second device. Nothing is going to completely take away all of your pain. Would I do it again, yes I would because the two devices give me tools to get me through the day, everyday. One comment I do have to say is that all intrathecal device reps need to educate er rooms on what you have implemented in your body because the 2 times I overdosed the er departments treated me as if I was a drug addict even after they were made aware of the device.
