Vacuum assist to IPP (Inflatable Penile Prosthesis)

[Lost Sheep]

Would there be any benefit (or danger) using a vacuum erection pump to make it easier to inflate an IPP?

I have read many reports of IPPs being difficult to inflate in the first few months after implantation (attributed to the pump bulb and valve getting "broken in" or maybe scrotal tissues getting "used to" the activity). So a little negative pressure might make it easier to get the saline into the tube - as long as it does not disrupt any penile tissues sandwiched between the implant and the skin.

Is there any wisdom on the forum about this concept?

The VED has Zero effect on the IPP. My experiment shows; you can pump the IPP, then pump with VED then deflate the IPP and with zero effect from the VED. The penis will feel pressure from VED and still deflate the IPP.

The experiment I envisioned would be in two parts:

Part one, to pump the IMPLANT, observing how much effort/pressure it took on the bulb in the scrotum. Then deflate.

Part two, apply a vacuum with the VED. Then pump the implant and observe if there is less effort/pressure it takes on the bulb in the scrotum.

How much vacuum is applied might make a difference, but the VED is NOT intended to produce the erection in the implanted penis, but merely to make filling the implant easier.

This is different from what you described.

An IPP needs no vacuum assist. If you start messing with it you could really screw it up. What are you trying to do rupture the cylinders? Also the tips are into the glans and need to be left alone. Using anything on an IPP (except maybe a condom) is unnecessary and inadvisable. Does anyone concur?

Concur!! The implant is a closed, sealed system. Using a VED will do nothing, except as Donnie said, "screw things up".

Ddbryan, jimbruski, I do not disagree. The fact is, I do not know. What I do know is that a large number if men report difficult inflation (hard to squeeze the bulb) in the first few weeks after surgery.

As I posted before, from a purely hydraulic viewpoint, vacuum assist might help, absent dangers such as separating the glans from the implant, etc. Unknowns.

I can imagine any number of bad effects, but, given inflation difficulty early on, the advantage of a small vacuum assist is intriguing.

So, I posed the question asking if any actual injuries have occurred, and if so, what they were and how they happened.

Improvements do not occur without questions, even the apparantly dumb ones may have the merit of a viewpoint not considered by mainstrem thinking.

Lost Sheep,

Maybe a better question would be; What would be accomplished by using a VED and what would be the mechanics involved, (i.e. Drawing blood into the penis enough to support an erection)?

Lost Sheep,

I believe, but am not certain, that a vacuum cannot effect a change around a closed system such as an implant, thus cannot improve pumping characteristics because it cannot change the atmospheric pressure in the closed system.

I appreciate sparing with you. It makes me think, and like you, I'm just not certain!!

I agree Donnie...especially as to the potential of damaging the seating of the cylinder tips in the glans. Perhaps somebody should message AMS or Coloplast and ask them, but I think the potential for disaster is far too great from a logic standpoint...
