There is one other manufacturer and that's Convatec. Convatec will send you free samples but you kind of need to know what your stoma is like, is it concave, or does it stick way out, etc. An ET nurse can describe your situation and you can call Convatec for free samples. I am VERY surprised that your nurse only uses on brand of product. It's not about selecting a brand but getting the right appliance to the ostomate.
