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.
