I was analyzing this design, which I think is ingenious, and while im new to PE im not new to engineering, and the vacuum concept is a good one. Another possible alternative though that would remove the need for a noose but also be more cost effective that a brand name product piece is actually a sheepskin condom. They make sheepskins that are nearly indestructible, completely airtight and very comfortable. You could use two, of course this doesn't work with sex, but here you could put one on, then put your first sets of string (i believe you used para-cord) but you could use something finer, like plastic wire. Put the wire through the outer condom, and let the airtight sheepskin act us your vacuum hose. Let me know if there are any flaws in this as I only was thinking about it and didn't try it at all. Oh and to deal with the lack of erection in a condom, they do make little condoms, how sad it is.
