In resuming my stent design and usage I have had two main considerations; cleanliness, and safety. My latest effort is pictured.
Cleanliness is relatively straightforward to manage. Using sterilising products on both the stent and the body is easy. There are plenty of products available plus soap, water, and disinfectants. So far there have been no problems although I have noticed a bit of discolouration around the metal ferrules. The next version will have them replaced with plastic ferrules.
Safety has been more complicated. The last thing I want is a trip to the ER (or A&E here) so I have adapted the Cathdiap stent design in two ways
