Jachut and Ddiedre, thank you so much for your replies. I understand that the results aren't in yet for the actual longevity of the band. And I don't have a problem with implanted artificial devices. I actually had a porta-cath for about a year about 20 years ago when I was being treated for cancer. I am just the type of person who tries to look at all the options and all the information before I make a decision. Sometimes I over-analyze to my own detriment. Anyway, this site is a wealth of very good information and I am so glad I found it. Thanks again, guys.
