Abstract
A system, device and method are presented for utilizing stretchable active integrated circuits with inflatable bodies. The invention allows for such operative features to come into direct contact with body structures, such as the inner wall of a lumen. Such direct contact increases accuracy of measurement and delivery of therapy.
