I am truly sorry to learn of your medical equipment failure. I hope someone is taking a very serious look at the responsibility borne by the repeated supply of faulty/failing equipment. Mine is still functioning well, and I can surely relate to the fear associated with equipment failure....after all, what would any of us do if it worked, then stopped.

Surgery is hard on the recovery side of things, so I truly empathize with you in the concern regarding having to have replacement work "back to back" and so soon.

Hoping all of the best for you,
