1. An apparatus to deliver ablative therapy to a tissue, the apparatus comprising:
- a stretchable substrate;
stretchable circuitry disposed on said substrate and being configured to remain functional upon conforming to a surface of said tissue, said circuitry comprising;
a facility to deliver ablative therapy; and
an array of sensors generating data indicative of an electrical conduction of said tissue;
an output facility comprising a display; and
a processing facility in electronic communication with said circuitry and said output facility, said processing facility for receiving said data indicative of the electrical conduction of said tissue and configured to;
generate a map of conductive pathways in said tissue based on the data indicative of the electrical conduction of said tissue, andcause said output facility to display said map.

Abstract
System, devices and methods are presented that integrate stretchable or flexible circuitry, including arrays of active devices for enhanced sensing, diagnostic, and therapeutic capabilities. The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a the brain, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy. Further, the invention enables the incorporation of both sensing and therapeutic devices on the same substrate allowing for faster treatment of diseased tissue and fewer devices to perform the same procedure.
