Maximize Pumping Power (Hands on approach)

[Fernando]

The study.

Is there any literature on electronically controlled implant devices?

I read something about heat activation. It seems like something like that or a mobile app connected implant have big disadvantages since it’s not self contained in the body. Perhaps a button in lower abdomen underneath the skin. Curious how they’re thinking about this.

Yes, there have been animal trials and cadaver trials on a heat-activated one-piece device that erects in a manner similar to an inflatable. Look up "memory metal penile implant"

It would be made of nitinol or something like that.

Mentioned in a couple of threads on FrankTalk in the past couple of years.

Right, I’ve seen this. IMO, needing a secondary device not connected to your body in order to activate the erection is not as desirable as even a pump.

I agree. A compromise would be the entire device (battery, electric pump and control unit) contained inside the body with only a transcutaneous charging device the only external device required.

One form might be a scrotum-implanted 2 position rocker switch and a valve that offers two paths between the reservoir and implant - both being one-way valves. The rocker switch's "ON" position would inflate the implant with the the deflation path closed. The "OFF" position would close the inflation path and open the deflation path.

A man (or his partner) could achieve an erection simply by manipulating the rocker switch.

I have seen one estimate that charging the battery might only be required once every month or so. This would, of course, depend on the size and quality of the battery and the frequency of erections/sexual activity.

In the electronic world, everything is a tradeoff.

Batteries will need to be replaced every several years. What would be a minimum acceptable service life? The further inside the the body the battery is placed, the more comfortable it will be but the more invasive will be the surgery to implant and later to replace. The larger the battery, the longer it will last between charges but the longer it will take to charge.

What would be better? A battery that would last for 5 inflations that could be recharged in say 3 hours or one that would last for 15 inflations but take 8-9 hours to charge? I'm pulling these numbers out of the air but the principal holds.

How large/powerful would the pump need to be? A more powerful pump would mean quicker inflations but would be larger and would drain the battery at a much faster rate. What would be an acceptable time to inflate? Erection in one minute? 5 minutes? 10 minutes?

Just some things to think about. What tradeoffs would you be willing to make?

Mike123, I think your question is valid but it is aimed at the wrong market. To a man with poor hand dexterity or strength. The trade off is no implant or 1 that has the limits of your question. I bet that most men in at least the initial implantees will gladly take the trade off.
As those guys provide feedback, the battery & pump would evolve to better suit the needs to that first & later markets.
I tried to read up on the early development of the inflatable implant a few days ago. The early implants were pretty crude compared to what we can get today. I'm fairly certain that some similar process would happen with the electric pumps.
Just my thoughts.

I had thought about an external device that captured the pump and then either manually like scissors or electro mechanically like a milking machine would pump the pump. deflation in the normal way. CAD and a 3D printer could make a prototype

The article cited in the OP said "batteries could be recharged extracorporeally by wearing a belt-type recharging device during the night 3–4 days per month." (I wondered if once a week would have been better language - and that schedule probably would be more convenient to schedule in most people's lives.) Connection to the power supply would be no more problematic than the air supply for a CPAP machine.

The article already mentioned heat and electrical charge as possible activation vectors. Why not a magnetic field? A material that polymerizes into an expanded and rigid state in the presence of a magnetic field would be very nearly ideal.

A one-piece implant (one in each tunica albuginea) filled with such a fluid could conceivably produce an erection with a magnet placed in proximity (I am thinking of a magnetic ring placed over the penis and scrotum which would be minimally obtrusive - might even be an enhancement if there were a suitable bump to put pressure on a nearby clitoris) It the ring were not acceptable, a magnetic anal insert might do.

The requirement for proximity and magnetic flux strength would be a challenge and adjusting how hard the erection is might require different strength magnetic tools but all this can be addressed. The need for the auxiliary magnetic tool would be objectionable to many and certainly ever having an MRI would be ruled out. TSA would CERTAINLY be amused.

"Bottom" line is, if I were able to get an erection simply by sticking a wand up my butt or putting a ring over my genitals instead of having to pump up my scrotum and anticipate that some day my pump might fail...I would be hard pressed to choose between the magnetic dick and the (current technology) hydro dick. (Balance the pros and cons: Need for added tool and MRI/TSA effects vs more invasive surgery and probability of revisions over time).

These all sound great. I wonder what the time frame is. I need some more time to wear the one I have out

Not more time. More sex.
