How long does the average inflatable implant last?

[LastHope]

Here's the failure distribution from a study...

Results: We identified 276 revision procedures, 68 of which met inclusion criteria (46 BSCI and 22 CP). Revised CP devices were longer than BSCI
devices (median cylinder length, 20 vs 18 cm; P < .001). Log-rank analysis revealed a similar time to mechanical failure between brands (P = .096).
CP devices failed most often due to tubing fracture (19/22, 83%). BSCI devices had no predominant site of failure. Between manufacturers, tubing
failure was more common in CP devices (19/22 vs 15/46 for BSCI, P < .001), while cylinder failure was more common among BSCI devices (10/46
vs 0/22 for CP, P = .026)

My unscientific opinion is that the AMS may be slightly better; it doesn't seem to have the tubing issue the Titan has and which Coloplast refuses to fix.

I’ve heard the weak point with Coloplast seems to be leakage of cylinders weakened by dog ears, especially in longer cylinders. But I think I was told by one of the surgeons i interviewed that AMS pumps fail more often than Coloplast, which is why AMS came out with the Tenacio pump.

I knew that about the AMS; I'm aware of the "dog ears" with the Titan, but didn't know it was a point of failure. That must then be added along with its tubing issues, which I know others have mentioned here. So, that's two strikes against the Titan then.

To add a third strike on the Titan, from what I've read on here the deflate button is a bit tricky to push. The AMS MS pump (old one) has where it can get stuck (sticky valve) but most times it can be fixed without surgery. The new pump Tenacio does change things up but it doesn't have the valve "pop" or the "buzz" while deflating anymore, when you press the deflate button you "might" feel a slight click and then it start to deflate. I was just implanted with the Tenacio yesterday Feb 18th so I haven't been able to play with it yet, only played with the mock up one the Boston rep showed me.
