Biomedical engineers at the Georgia Tech are testing a device that, when implanted, mechanically lengthens an existing artery in patients preparing for coronary artery bypass surgery (CABG). The lengthened artery, when harvested and used as a graft, has the potential to greatly improve the long-term outcomes of bypass patients.



Designed to stimulate growth in the gastroepiploic artery – a small, disease-free artery about 3-7 mm diameters in size and located below the stomach – the device has shown to be effective in lengthening arterial tissue in pigs by as much as 30 cm – enough for a patient to undergo at least two CABG procedures, researchers say.
