Like many here on the forum, I used a vacuum pump prior to getting an implant. I have seen several posts saying that a VED is not to be used post-surgery. Having been implanted 11 weeks ago, I understand the knee-jerk impulse to great caution. However, I do think that VED could actually be helpful in healing. Healing anything in the body is all about the presence of lots of blood. Without lots of blood, no healing.

From a mechanical standpoint I can see the danger in using a vacuum when the implant is un-inflated. Because the chambers are empty and low pressure, the vacuum could possibly pull tissue away from the chambers.

However, if the chambers are at maximum inflation with lots of pressure within, I can't mechanically see how anything harmful could happen. The blood would fill the penis around the full chambers and could, therefore, aid in healing the tissues. Also, it would help expand the tissues to aid in regaining size.

Has anyone used a vacuum device post-surgery? Is there something from a mechanical standpoint that I am missing in using VED in this way?

From what I've read here and elsewhere, VED after implantation is not recommended. I never liked the VED before my surgery, and I can't imagine using one now myself, but why not check with your surgeon?

Mechanically I am the reverse of you. If you were going to use a VED to inflate I think your penis should be deflated with the valve in the inflate position. If the VED pulls some fluid in to the cylinders it is better than expanding the cylinders already inflated. IMHO pulling vacuum on an inflated cylinder might burst the cylinders under the vacuum.

Normal use of a VED is trying to stretch a flaccid penis, pre-inplant. I am not sure the tissue attaches to the cylinders but a pocket for them is created when you inflate after having an IPP. Once you deflate the tissue is left where you inflated it to. When you squeeze the tubes to deflate them I don't think the tissue is attached are it would hurt each time you did this.

Unless you have a AMS LGX, it is the only device that would be able to expand to fill length area you created by VED. Since I have a CX which is not going to get longer, it is an academic question for me. My tubes are up against my glans and if my penis was lengthened by VED, my CX tubes would not expand to fill the space. Seems like you might end up with a floppy head.

Interesting question! NOT a URO nor an IPP mechanical engineer.
