Nitinol implants, Andrew Kramer

But you'd need to use an external device to get erections, whereas an inflatable implant is more self contained.

Also, one advantage of an inflatable implant is that you can keep erect for however long you want to. This won't be possible with the memory metal implant.

Keep it hot with friction.

Sure, there is nitinol in the implant (according to the announcement), which also says "When not in use for sex, the implant can be manually pushed down for concealment, for a discreet, natural appearance". Clearly suggesting that the implant does not use the temperature-activated "memory metal" temperature sensitivity of the nitinol, but only its malleability (ability to maintain a shape into which it is bent, but not ability to return to an original shape when it cools)

I thought the heat of your hand was what allowed you to shape the metal.

104 Degrees Fahrenheit has been mentioned as the phase-change temperature. Attained by holding a device (wand) that emanates a magnetic field of some kind.

I still wonder what happens if you spend any time in a sauna, or in Yuma, Arizona.

And what if you lose your wand?

What if you're fucking an Eskimo?

Hey, hey, hey, there. Some Eskimo's are HOT!

Note that I live in Anchorage. While it is not actually the real Alaska, you can see it from here.

Dunk your dick in boiling water?

Actually a mug of hot chocolate might be better. Women LOVE chocolate!

The Tactra implant your link connects to is a simple malleable, not the nitinol "memory metal" pumpless, erecting implant still in trials (last I heard, in 2019, animal trials with cadaver trials in late 2019 or 2020, as I recall)

As far as I know, Dr. Kramer is still doing surgeries but getting in contact with him has been problematic for some members. I suggest contacting

1) Maryland State Certification Board for Urologists
2) Boston Scientific or Coloplast. He certainly would be in their list of approved implanters.

I think I found him in Cape Cod, Massachusetts.

If that's not the nitinol implant, then why does it say "silicon over nitinol" in the description? Do you know where I can look to keep updated on the progress of the nitinol implant?

Nickel-Titanium alloys (Nitinol) can have more properties than changing state with heat or cold. One of the more common features of Nitinol that have been used in eyeglasses for possibly 15-20 years is the ability to return to its designated shape after being extremely distorted. Nitinol-based frames will return to their shape even if twisted or bent.

There are even Nitinol stents that are used for urological purposes that are basically springs that are inserted into the bladder sphincter and then flushed warm water to set in place and stiffen the wire so it doesn't flex. To remove these temporary bladder stents, they flood the urethra and stent with cold water and it softens the spring enough so it can be pulled out with a tool in a cystoscope, as a long metal wire instead of a formed spiral.

It's very possible that the Tactra Malleable uses a different property of Nitinol alloy for its properties, as opposed to the heat-to-erect implants that are in development.

What you are referring to is the magnetic induction penile implant invented by Brian Le. It was successfully tested in a cadaver in 2019. I believe Boston Scientific is helping to fund the research on this. Information since had been scarce. Articles that I have read said that hot tubs, baths, showers, etc will not activate the implant. I really hope it comes to the market. Personally, I'd rather carry around a wand then have to worry about revisions.
Competition spurs innovation and we benefit from improvements to these products. It would be great if penile implant surgery would be a one and done experience.

I'd still need an external device to activate it :/

It just feels emasculating to have to resort to something external.

I hope if they launch the new implant, they still continue to make the old implant for people like me.

New materials might offer pretty interesting solutions for the future. There are metals that can switch between states by simply having electrical current ran through them.
This, combined with something like Neuralink might allow "spontaneous" erection, controlled by the brain...

And these types of implants might be a good solution for some pathologies that current implants don't "service" well.

I don't see any of this high tech stuff as being cheap. I'm not sure how much upward price pressure the market could bear. Remember, the insurance companies hold the purse strings.....tightly.
