A biodegradable polymer bandage manufactured by Geron , a firm from California, can reduce bypass failures by preventing blood vessels from thickening when it is wrapped around the blood vessel.
Experts at biopharmaceuticals company Geron point out that the thickening of transplanted blood vessels is believed to occur due to the stress of being transplanted and suddenly having to handle a different blood pressure and flow rate.
