Oh PS… the flexNT is 8mm wide in total with no wedge shape… the 7mm wide start of the wedge shape of other flex devices helps needle installation a whole hell of a lot. With the flexNT, the installer may need to kinda jam a corner in first, then pry it into the incision, if you know what I mean. Alternatively, the blade of the needle can be used to slightly open or widen the incision once the initial pocket is created. I’ve installed a few flexNT with a needle and it’s not easy.
Alternatively we are exploring the idea of adding a little wedge start shape to the flexNT… it’s extra material though that exists on one side for no other purpose than to make needle installations easier… so some people may not like the idea of extra useless material going in.
Final note… the needle method is really not suggested for difficult area installs like the finger. Fingers are delicate and difficult to work with and definitely requires a very steady professional… preferably a medical doctor or hand surgeon… in fact, hands are so difficult that most general docs or even general surgeons won’t even touch them and refer you to a hand surgeon.
