  1. Similar to doogles' initial reaction, I'm about to fall asleep, but wanted to say that your alternate retrieval line illustration is clever but I think much less safe. In your original pic, the line was looped around the proximal end cap such that the line itself would have to break for catastrophe to strike. In your second pic, the line would only have to cut through the silicone to wind up with a similar result. Of course, I'm not tugging on and testing things for added confidence, but I wanted to throw the idea out there for consideration.
  2. Hey, Ferix. Hopefully others with a more complete history all around can chime in for you, but I've experimented enough to have experience and with prototyping for safety and avoiding UTIs. I'll share my methods. Cleaning: Definitely wash with soap and water to clear off solid, dried, and/or stuck-on particulates. After that, I submerge everything in ~70% isopropyl alcohol (apparently it's better than higher concentrations for disinfection), then the boiling water which helps to rinse and evaporate the alcohol as well as possibly getting microbes which might've survived the alcohol for whatever reason. The hot air gun idea makes me nervous for you. I'd be worried that it could easily reintroduce things which you'd have otherwise just cleaned off. Passive air drying seems less risky. If I recall, the guy at siliconenozzles.com actually recommends a fresh paper towel and an unopened Ziploc bag for storage at this step. Retrieval: At some point, someone here suggested braided fishing line instead of monofilament for comfort and safety, and I agree. My personal trouble was trying to find one without green dye to help disguise it for wary fish. Dental floss has never given me enough confidence to try, but seems to work for some. Similar to fishing line, avoid flavors, dyes, etc. Structurally, I love the simplicity of your design. If those steel end caps are as familiar as they look, then the threads aren't very sharp, right? You'd be relying a lot more on a friction fit than the threads actually digging into the silicone to stay in place. If it takes less than about ten pounds of force to pull one end out of the tube, that might be cause for concern. If it seems stable, I'd try for redundant safety by running your line through the whole tube, then looping it around the outside of an end bead, and finally back into the tube going back the way it came in. It might compromise the friction fit element, but would be much safer in the event that things come loose while you're wearing it since everything should still come out by pulling the line. Preparation: I go HAM and usually use a cath insertion kit, but have also used makeshift supplies to kinda DIY it. Benzalkonium chloride wipes after washing with soap and water, a sterile water-based lube (less urethral trauma should mean lower infection risk), and being really careful about what touches what before everything is in place. Sorry this reply turned into a novel, but I hope it gives you some helpful ideas about how best to move forward as safety as you can. Best of luck to you.
  3. I have! It was a long time ago though, so I was too inexperienced to have given the idea a real assessment. I used the one called The Garter, because it's shape looked like it'd offer a good balance between gentleness and stability. One of your OG-style 90° thermoplastic tubing sections for the bend at the bulbous urethra and a pair of redundant retrieval loops (each running through both pieces) made it a working prototype. Only having rigid tubing at the bend created an interesting kind of stress incontinence. Obviously, you could try running tubing through the whole thing, but you might have to get creative in order to fit it all in there ? I couldn't wear it for longer than a few hours at a time, but my pipes were pretty untainted back then. It was remarkably comfortable for it's size relative to almost anything I've tried since, and the combination of the plastic bend and the shape of the silicone seemed to work well enough at holding things in place to merit further exploration. If the plastic tubing you use was the last pic I saw with a small pink retrieval loop, then that would probably be quite a stretch for the silicone. I think I used the plastic tube from an empty spray bottle. Here's another area where softness of the silicone comes into play. Softer means much more stretch and comfort, but it also becomes very easy to tear as you approach the softest options, especially where it's punctured for retrieval lines. When the interest cycles back around, I find it probably too easy to get lost on their website browsing the designs and playing with ideas inspired by them. <<< Public Service Announcement >>> If this design interests you, please read the recent posts by Doogles and then think about going to pull your retrieval line(s) and feeling them tear through the soft silicone... like a wire through cheese... as you finish pulling a bare line from your body. Ours is a wild endeavor, and deserves a correspondent degree of respect. Play well, friends ?
  4. Hey cathdiap, I have several pieces from them. I think they can be really interesting and fun used in the way they were designed to be used, but they also open up a whole new area of stent design (with new problems to solve). Maybe order one that you think you'd like to use unmodified and then go from there. The material softness has important implications for stent design, so ordering their softness/hardness sample pieces would be a real benefit: https://siliconenozzles.com/Silicone-Evaluation-Triangles-for-Softness-Firmness-Assessment-TriangleSampler.htm Sharing your continuing adventure down this path has made me and others feel less alone in the world, and that deserves thoughtful gratitude. Please feel free to ask more specific questions if you have any, and best of luck on your next design!
  5. Oh, neat. I used to live in Columbus, and still visit fairly often. Would be down to hang out if people wanted to get together.
  6. Hey, guys. I took a long break, so I forgot a lot about what needed to change for the last stent I made (and have been wearing since last night). It's functional, definitely inserted all the way, is completely smooth, but is almost uncomfortable enough to want to remove. That sounds like a length problem, right?
  7. Sorry, I'm gonna be that guy. It actually does look like homeboy has a diaper under his overalls in the daycare scene. Interesting.
  8. @cathdiap "It was nerve wrecking to slowly wet my diaper in front of them, but I have to say it was really cool to be treated and accepted as if I was a true incontinent person by these professionals. I know it may sound strange but somehow I felt less crazy afterwards." This feels important. Honestly, prior to about a month ago, I would have simply understood this as exhibitionism sprinkled with some self-acceptance (with which I've had some experience). Recently, I started wearing for periods of several days in a row, but specifically around certain people that used to generate too much fear to be able to continue. It has spurred meditations on the same sentiments you mention. I'm still going out of my way to be reasonably discrete under clothing, but really breaking through the anxiety around thoughts like "omg what will I say if this person notices" is a deep and powerful kind of liberation. Stent update: Malecot stent rev.3 only survived about 12 hours (including overnight). Standing flow was fine. Sitting flow was pinched somewhere until slouching with terrible posture straightened the hips. Sitting comfort was also pretty poor because of where the distal end settled in the urethra. Lying in bed, there was still resistance somewhere. I could only get a flow going by tightening my abs. Before falling asleep, I noticed a tendency for inward migration, and I woke up with the fairly sharp sensation of fishing line being pulled across the tip of the penis, so that's when it came out. Slightly dejected, I'm reconsidering the concept of bypassing only the outer sphincter. While drips seem preferable to flows as far as dry pants are concerned, I think I'll risk the embarrassment of a leak over the embarrassing and painful urinary retention due to a perpetually activated outer sphincter that feels like it could press coal into diamonds. Stent on, friends.
  9. Fantastic update, @qwerty. Thanks for sharing it. My most recent iterations have been focused on total stent length, and what that means for balancing comfort (too long: ending at a sensitive part of the urethra) with security (too short: kegels sort of grab the stent and push it inward). Rev.1 was a little too short. It felt like it terminated somewhere in the middle of the outer sphincter, such that flow was inconsistent. Rev.2 was too long, which made it pretty uncomfortable. There was no forgetting that it was there. Rev.3, about 1cm shorter than Rev.2, was just inserted about an hour ago, and so far feels pretty good. I find that it takes somewhere between 12 and 24 hours to get a fair sense of how it feels and what's likely happening inside, so time will tell if this is a Goldie Locks stent. I can say for sure that it's long enough to feel through the scrotum. Pretty sure that wasn't the case for Rev.1.
  10. After I submitted that post, I realized the awkward implication. Not my intention, for sure. The main idea was just that a format like a wiki or something would be a more efficient tool for organizing the fair bit of collected knowledge here. Not as a replacement, but as a more convenient reference for when anyone is looking to do stent design work. Speaking of that update... I feel like a created more questions than I answered. For example: Do we know if the prostate can swell toward the bladder when you're, say, going to town on PornHub? Can't be sure, obviously, but I have this sneaking suspicion that the distance between the two sphincters may not be the same at all times. Iterating on the malecot makes things sore pretty quickly, so I'm going to try the underinflated foley method again. Last time, I punctured the fill line trying to plug it with a piece of hard plastic that was too big and too sharp. I also didn't like how it encroached on the space in the drain line. That's valuable real estate ?. Can someone remind me what people use here? Just found this and remembered that weed wacker line was what I tried, but it seemed way too big for the tiny fill line. Admittedly, I'm assuming there's basically only one size of weed wacker line.
  11. I made my most successful design to date about three weeks ago. As I was trying to come up with the most useful way to post an update here, I couldn't help but think that it would be far more efficient to curate all the experience and wisdom from this thread into it's own website for safer and easier consumption (by newcomers and veterans alike). Maybe someone with more web design experience than me (basically none) could make quick work of such a project. Just thought I'd put the idea out there.
  12. I'd wager that many of us would agree. Earlier on in one of these stent threads, a few people were trying to brainstorm some (relatively) safe way to create a urethra mold so that any one of us could solve this puzzle for ourselves without the often significant costs of trial and error. That being said, I really like how you approach the project. Clear and structured thinking comes across in your clear and structured writing. Thank you for a very thoughtful design update and analysis.
  13. Randomly browsing around Amazon just now and saw a USB borescope... which they also refer to as an endoscope... anybody ever try using one to look around places we shouldn't look? My main curiosity with it would be to try to get an accurate measure of the distance between sphincters to take the guesswork out of stent design. http://a.co/d/dbk8JmB
  14. @Old_PA Thanks! Hopefully, I'll find an iteration of this stent in which I'm confident enough to leave it in, and then I'll need to use this advice. @cathdiap Shorten, you think? I'll give it a try for round three. Thanks! On the topic of length, for the final bit of pushing through the bladder neck during insertion, I have actually been removing my pushing rod and just sort of pinching the urethra closed and working the stent in by hand from the outside, with my thumb on top of and at the base of the penis and my fingers just about behind the scrotum. Once I feel it pop into place/through the bladder sphincter, I can still feel the outer tip of the stent in that area. Is this also the case for any of you with successful designs? (Realizing this, it's understandable that sitting down would pinch the urethra closed and cause a flood upon standing.) I'm not sure how near the outer sphincter should be relative to the outside of the body, which makes me unsure if I should or shouldn't be able to feel a successful stent with my fingers from that spot. Regarding the malecots, I found a local surgical supplies reseller. Small business, local pickup, probably thought it was weird when I said I wasn't with some medical institution, but in the end I suppose it wasn't a problem. If it's relevant, I had been pretty close to ordering some on ebay. Might be worth keeping an eye out.
  15. Update: Several thoughts... Moving the bent tubing nearer to the end seems to feel better. I had a decently full bladder upon insertion, and the stent did its job pretty much how you'd expect. If I can feel anything, I think it's maybe the back of the deflated bladder touching the tip of the stent near the wings. It doesn't feel bad; just a slightly noticeable sensation consistent with normal sounding/cathing feelings. That gave me a thought, though... if the bladder will remain deflated because it will always drain before it has a chance to inflate very much, then the back of the bladder should always be putting at least a little bit of pressure on the stent as if to push it out. I wonder if that means that the bent inner tubing section isn't necessary at all, which would dramatically simplify the design. In the time it's taken me to compose the above paragraph, I've noticed some dull sensations near where I think the kidneys sit in the abdomen, which is relieved if I no longer sit straight up. I've been chugging water pretty steadily, and there's a decent little flood when I lean back in my chair. The other thing is a slightly weird sensation in my left testicle. Not totally foreign to me, but interesting that if I ever engage in urethral play and something testicular is happening, it's always that one. I have to shower for work in a couple hours, so I'm debating the pros and cons of leaving it in for further observation, especially while moving around rather than just sitting at my desk. I have one of those locking incontinence penis clamps, but something tells me that it shouldn't be relied on because otherwise it'd be a more commonly discussed device. Anybody have any experience with condom catheters and leg bags? I'm trying to think of ways to remain stented during times where a diaper would be too awkward (around coworkers, family, etc.) I suppose the price we pay for incontinence being voluntary is that it would be a lot harder to explain upon discovery.
