Latest refinement of the "pumpless inflatable. As before, the pumping action takes place inside the rear tip extender (RTE) by using a flexible, but inelastic capsule trapped within an articulated joint between the upper and lower portions of the RTE. The two (red, orange and gray) inflatable t...

Does anyone know of a treatment for Erectile Dysfunction caused by venous leakage? It seems to my untutored mind that an inflatable sphincter (similar to what is used on the neck of the bladder - an artificial urinary sphincter) might be a solution. It seems to obvious to me. So, there must be a les...

The volume of ejaculate (cum) is almost totally produced by the prostate. If your prostate is healthy and you are eating and drinking the right nutrients you should have a healthy amount. But as we age, we can expect less. Also, if you ejaculate often, you will produce less per event. I knew a gal w...

I am at the start of the process of addressing my erectile dysfunction. Here is my list (so far) I appreciate your time as you appreciate my concerns. This is a surgery not necessary for life, but important for quality of life and so I am carefully weighing my options. I also want to stay with the s...

Question: how would you squeeze the pump if it was inside a rigid enclosure? I suspect you are right, constant flexing of anything, be it tubing or wire, especially where it meets or passes through a solid surface, is subject to stress and wear and eventually fails. I can count on maybe two years f...

according to dr kramer what usually breaks is the tubing close to the pump Does that imply that the tubes flexing during the pumping process eventually cause failure? If the pump were inside a solid housing, would that help, I wonder? No (or, at least, a lot less) tube flexion. I have been working ...

Since the original question seems to have been answered (leaving open the option for more input), I have an adjunct question. My scrotum is small enough that it has little room for its current contents (two testicles only). I doubt if there is ROOM enough for a valve and pump. Is that a potential pr...

AND... you get your windshield clean, too!

I have seen many drawings of implanted prosthetics and every one of them show the RTE's very close to the surface of the skin of the perineum. This suggested that a rocker switch controlling an inflation/deflation valve might be able to be placed there if it could be protected from accidental activa...

Having been advised that combining the two Rear Tip Extenders (RTEs) into a single piece is not doabale, here is an improved design which retains the feature of inflating the penis by simply manipulating the penis (as in foreplay and coitus), thereby emulating a natural, organic erection. The two RT...
