Randy Atkins:  Prying open clogged blood vessels damages their inner lining.  The body’s quick-repair process can then cause scarring that re-narrows the blood passageway, says Steve Bollinger, president of Pervasis Therapeutics.

Steve Bollinger:  Our stuff prevents that scar being formed.

Randy Atkins:  Pervasis is engineering a gelatinous bandage to cover the outside of a healing blood vessel.  Bollinger says it gradually releases biochemical signals that get inside and calm the healing process.

Steve Bollinger:  Keeping the cells and all of the functions of the vasculature working normally while that inside lining repairs itself naturally.

Randy Atkins:  The bandage biodegrades away on its own.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.

The biochemical bandage is in clinical trials and a few years away from general use.  To find out more about this story, go to wtopnews.com and type in keyword "Innovative Engineering" or go to <www.nae.edu/radio>.
