I bet Straydog will be along soon to answer your question.
My Dr mentioned this to me as well the last visit I had with him. However; I think it is way too early for me to even think about it. I hate taking the oral meds, and have heard many good things about the pumps, and my Dr would rather see me using it instead of the oral meds. He wants to see where I fall on the healing process before we go there.
Good luck with it, and Straydog won't steer you wrong. She knows her stuff on this. I'm thinking PaLAdy has one of these as well, and maybe she will chime in here for you.
