Codman 3000 - Baclofen Pump

Hi, just new on here, my father had an intracathetral baclofen pump implanted in around 2005, it was the Codman 3000, is there anyone on here that has had problems with overdose and underdose of this pump? or any problems with the silicone seal where the baclofen is injected, this was not a programmable electric pump but a pressurised gas pump and was one of the very first models of these types of pumps. I am desperate to find anyone that has either got or had the codman 3000 (also known as arrow 3000) or has a close friend/family member with this pump.
