He recently published (2019) a first in man research pilot study enrolling patients into a protocol looking at low frequency ultrasound treatment coupled with stem cell implantation in the legs of patients with the most severe vascular disease scheduled for amputation. This first in man study was in conjunction with the NIH and paralleled their study of animals which showed promising results.
