I am wondering what things are/would be helpful to someone who catheterizes -- either learning for the first time or that has been doing it for awhile.

I am in marketing at a medical equipment company and want to create something (whether it is text or an actual item) to give people that will help them with self-catheterization. Can anyone tell me what they wish they had when they were learning or something that increases convenience?

I have seen mirrors and things like that -- but what is truly helpful or what is something you wish existed to make things easier?

There are how-to videos and DVDs -- are these helpful? What is good and bad about those?

Thanks.Liz
