ET,
Sorry, wish I had an answer for you. Have been on a hunt for catheters for many months now. The Marlin and Medina are too flexible and I have been told by several suppliers that there is a production problem. And some companies no longer make the product .
This is certainly effecting my quality of life in a very bad way. If you hear of anything please, please pass the information along.
Thank you
Best of luck
Jan
