Systems, methods, and devices having stretchable integrated circuitry for sensing and delivering therapy

摘要

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.

主权项

1. An apparatus for medical diagnosis and/or treatment, the apparatus comprising:
a flexible substrate; an expandable assembly coupled to the flexible substrate, the expandable assembly comprising a plurality of supports, each of the plurality of supports extending from a center of the flexible substrate to a respective corner of the flexible substrate, the expandable assembly being operable to adjust the flexible substrate from an undeployed configuration to a deployed configuration; and stretchable circuitry disposed on the flexible substrate, the stretchable circuitry comprising a plurality of electrodes and a plurality of stretchable interconnects to electrically interconnect at least some of the plurality of electrodes, the stretchable circuitry being configured to remain functional upon conforming to a surface of a tissue.
