That indicates the implant is maxed out on what pressure you can exert, and there is still fluid available in the reservoir. What we’re discussing is a situation where there is no more fluid to generate more pressure. It all depends on how much fluid is in the reservoir vs what can fit in the cylinders.
Imagine you have a reservoir with 130ml in it. At first when you start cycling you pump up as much as you can, let’s say the cylinders can take 120ml of fluid before your tissues are at max stretch. The pump will remain hard because there’s still 10ml of fluid that can be pumped.
Now three months later your tissues have stretched, allowing the cylinders to expand a bit, and you get an extra couple of pumps in and now you can get 125ml into them, and the pump is still hard.
Another three months pass, your tissues have continued to stretch and now you can get even a couple more pumps in, and you get 130ml into the cylinders. Oops, the pump bulb goes flat, as you moved all the fluid out of the system and into the cylinders. There is no more fluid in the bulb to keep hydraulic pressure in it. A slight vacuum forms and the bulb stays flat until you deflate.
There is no more ability for tissue stretch because you can’t generate the excess pressure for it. You are now maxed out in size and hardness for the available fluid volume. It’s just physics, nothing too odd about it.
