The pump / battery (it is a combined unit) gets fully replaced every 5 to 7 years so it will be a surgery to have the old pump removed and new one put in, but medication gets refilled every few months (depending on the season). The Baclofen is in a liquid form so for refills it injected via a needle into the fill port under my skin.I don't know if the pump needs to be replaced routinely or have the battery serviced. If there is more than one manufacturer check out the other brands. Maybe you can get an upgrade at your next service interval . I know some brands of pacemakers are rated to 3atm (66ft saltwater), some to 5atm (132ft sw) and one or two to 7atm (198ft sw). These are the pressures they were tested to, not the ultimate crush strength, so if your pump is rated to 30ft don't freak out if you hit 32 but don't push it either.
Other pumps look to be a simalar design so most likely simalar depth restrictions.
Looking at some stuff on this it seems most of the extreme crushing damage is from people diving to over 100 feet and long times at 60+ feet might make the motor unhappy, so there is some buffer zone. Depending how long I need to be at 60 feet I might be able to a full open water cert and just go places with shallow water diving, definitely something to talk to the doctor about when I it refilled.
