  • Flexible and stretchable electrodes for gastrointestinal implants
    Patent number: 10391310
    Abstract: A gastrointestinal stimulation apparatus and methods with an electronic controller and a flexible and stretchable electrode array with a central branch and orthogonal bilateral branches that wrap around a section of the gastrointestinal tract and can accommodate repetitive contraction and relaxation movements of the tract. Array branches have a flexible spring structure, stimulation electrodes, recording electrodes, sensors controlled by a controller and adhesion nodes that fix the branches to the tissue. The electrode array can sense the normal peristalsis from upstream tissue and produce a stimulus signal to stimulate the incapable intestine section to generate stimulation-induced contractions. Electrodes on the incapable intestine section can be used for stimulation or recording, the recorded signal from the incapable intestine section can be sent back to the electronics to form a closed loop control system.
