kevindhca Posted July 4, 2016 Share Posted July 4, 2016 I haven't posted much lately, crazy busy with work and preparation for my daughters wedding. I knew if I thought enough and developed the right techniques, I'd come up with the appliance. Unfortunately, the description will have to do for now. The computer is being stubborn and I can't upload pics from my phone. Start with a straight vinyl catheter. I use 16FR. You need a heat gun, steel ruler, razor knife, clamps, and a pair of pliers with a round notch approximately 14FR. I'm using a pair of electrical pliers that have a pair of smooth round notches in the jaws. Pre warm pliers with heat gun. Hold catheter in plier notch near hole where inner sphincter is. Heat inner side next to pliers VERY SLOWLY and tubing will start to swell. Use slight pressure to mushroom tubing against flat edge of pliers. The pliers will protect the part of the tubing from the heat and shrink it's diameter slightly. Measure from the narrowing about 6-8 cm and cut the tubing lenghtwise starting with a long sloped cut. Place the ruler on edge in the U and clamp down. Cut on both sides leaving a thin tail. Trim smooth and cut to final length. For me it's 19cm. I'll upload a pic a soon as I can. Link to comment
Hugo Posted July 4, 2016 Share Posted July 4, 2016 This sounds highly creative! A different design approach. I can't wait for the pics! Link to comment

Hugo Posted July 5, 2016 Share Posted July 5, 2016 Thanks! The stent is looking really great. I'm quite interested in your experiences in wearing it. While looking at the stent I am not sure if the filament, which you created by slicing the catheter lengthwise is as strong and resistant to tearing as a fishing line. Link to comment
kevindhca Posted July 6, 2016 Author Share Posted July 6, 2016 It's pretty comfortable. Doesn't really feel like anything is there. The filament is actually really strong. Way higher breaking strength than needed. It will stretch a lot before breaking, like an elastic. I use a piece of the tubing for insertion with the filament down the center. The end of the filament is just inside. I believe it's safer and more comfortable. No knots, completely internal, and easy to remove. Link to comment
Fakename4me Posted July 9, 2016 Share Posted July 9, 2016 Kevindhca, any chance of getting a close up of the part that you modified with the pliers? Link to comment
kevindhca Posted July 28, 2016 Author Share Posted July 28, 2016 Sorry, I missed that post. Really busy with work and getting ready for my daughters wedding. I'll take some close detail pics for you. It's going to be a few days though. Link to comment
Bettypooh Posted July 29, 2016 Share Posted July 29, 2016 Liking this design. Homogeneous with no loose parts to possibly move. IMHO the hallmark of best design is the absolute minimization of possible failure points which this does well Bettypooh Link to comment
kevindhca Posted July 30, 2016 Author Share Posted July 30, 2016 She's smart too. Turned me loose to do whatever I wanted Link to comment
James Oldaker Posted August 14, 2016 Share Posted August 14, 2016 I would love to see more pics if possible, someday I might try this Link to comment
Justmeinnh Posted August 22, 2018 Share Posted August 22, 2018 Another test- need to try smaller hole 3 inches from balloon. My holes I think are too big and very irritating. Link to comment
Fakename4me Posted August 23, 2018 Share Posted August 23, 2018 interesting. Thank you for posting. Link to comment
