I was at the siminar yesrterday and forgot to ask. He did say something about the Elise band, but I can't remember. What is the difference?

Actually I have never heard of the "Elise" band. Just "Realize" and "Lap Band". You might try googling it.

I think you mean the Realize band, manufactured by Johnson & Johnson. Lap Band AP is manufactured by Allergan/Inamed. Realize is 9cc while Lap Band us 10cc or 14cc. Lap Band's "inner ring" (the part that is inflated with saline) has a sort of scalloped effect so that not all of the surface is in direct contact with your stomach (the premise is that this reduces the chance of erosion). Realize's inner ring is smooth. Realize's port is a little flatter than Lap Band. They work the exact same way.

You haven't answered but if, in fact, you do mean the "Realize" band instead of "elise", as Parrothead Cathy assumed, then here's a link to a really helpful website. The page I've given you lays out a comparison between the two types of bands

Compare Adjustable Gastric Bands - LAP-BAND vs. REALIZE Band

Educated assumption ... googled "elise band" and got a bunch of hits for a rock & roll band.....

Yes of course I meant Realize band.
