Nope, those guys use glass beads inserted into the blood vessels (vasculature) feeding the tumor. This competitor is limited because the glass beads, even impregnated by Y90, have a diameter that clogs / restricts where they can travel based on blood vessel diameter to glass bead ratios. As the damaged tumor decays, it can release the glass beads into patient vascular system and for the liver tumors cause side effects. From your competitor web site:
Ask anyone in the x-ray tech world how easy it is to find glass beads on an x-ray... ;-((
RDGL is a product where Dr. K did the math to embed the Y90 at the molecular level into an already FDA approved liquid with FDA approved Y90 that gels at body temp. The device we have injects fluids into the tumor walls and tumor cellular interstitial spaces (of roughly 18 different tumor types) that quickly arrives at body temp and hardens to gel... no seeds, rice, darts, or glass marbles/microspheres of any kind that could travel thru a body to other organs. In liquid form it goes everywhere within the tumor... achieving gel state it locks in place all substance/cells until the gel decays after Y90 half life takes radiation to effective '0'; it does not leak from the tumor (even in a mouse size spleen tumor).
All the best ratios of brachytherapy with significantly reduced human safety risk over current approved methods and currently FDA approved for all non human animal tumors... Hmmm, They are also post 8:1 reverse split with AS reduction and have raised Reg A dollars in the Millys for human trials while partnering with the Mayo clinic to answer FDA questions?
