VA Treatment: Juxta Cures for Venous Ulcers, who has experience and did it work or not for you? If not, what did and how to get VA approval?

For the past 9 months or so, the VA in Houston has been treating my leg for venous stasis ulcers using the Juxta Cures system. I had previously had a similar problem back in 2009 in Tulsa and was treated with something they called a "unnaboot" (sp?) and it worked really well and I had no further problems until last year. I am not generally given to spontaneous ulcers and the ones I have now grew out of a singular injury and this "treatment system" causing further problems. I have asked to go back to the "unnaboot" system, but have been told the VA doesn't use that anymore. My Home Health Care Nurse (also a wound care specialist) thinks that better results can be had using Coban wraps and, since that was part of the previous system used, I am inclined to agree. But the Wound Care department at Houston seems hell-bent on using a system which I find irritating to painful, not user friendly and, IMHO, more damaging all for the sake of saving a little money? So I am reaching out to the community to see if anyone else has experience with this and see how they dealt with it.
