I had a Rigicon penile implant which is a malleable type of implant put in 2 years ago. This type of implant means I am erect all the time ..it bends down to store it out of the way. It is 2 rods with stainless steel springs inside covered in silicone coating. I'm 71 with various health issues getting this type of implant was one of the best things I have done. The other type of implant is an inflatable meaning itis like 2 balloons placed in the penis with a pump you access by pumping a bulb in your testicles. It is a much more involved surgery than the Rigicon type of implant. If you want some real answers go to a site called franktalk.com ..free to join all your questions about implants will be answered.
