In our practice, we are using proper wound care technique depending upon what the type of wound it is. We found great treatments for these hard-to-heal wounds including synthetic skin substitutes. Such as Apligraf and Dermagraft or couple of different other products that are out there. We are using recombinant DNA technology utilizing Regranex, which actually promotes healing by adding healing cells to the surface area of the wound. On very difficult wounds we are actually also using hyperbaric oxygen as well, referring patients to a hyperbaric oxygen chamber, in order for that to be used as an ancillary treatment too. I think this Prosit bandage is using something similar. The wound is not going to heal on its own for a variety of reasons, so lets add electrical stimulation to the actual bandage so it will help to stimulate the wound to heal itself much like you would use a bone stimulator to heal a fracture that has a hard time healing.
