Thank you all who gave me advice on catheter/convene system. We went for the convene system. It has taken a few attempts, he measured standard when I did it first, but it decided to shrink and ha to go for small. We have done nothing but chuckle at our attempts to get set up. At one stage Pat nearly choked laughing, when I said if I saw that coming at me I wasn't sure whether I would laugh or run. Today we seem to be winning the battle. Thank you again for the advice and support, thought it was nice to post something good instead of a rant
