    Abstract: An electronic intravascular device is placed in tight contact with vessel walls and is used for electrical stimulation and/or electrical recording of the vessel wall and surrounding target tissue. The electrodes may operate via connectors interfacing them to external hardware or may incorporate electronics to allow wireless power, information transfer, and control. The device includes an internal skeleton, a flexible substrate attached to the exterior of the skeleton, at least one pair of electrodes located on the substrate, and power and control circuitry connected to the electrodes. The power and control circuitry may include connectors for direct powering of the electrodes or circuit elements for wireless powering of the device by RF-based, optical-based, ultrasound-based, piezoelectric, or vibrational energy harvesting methods. The power and control circuitry may include circuit elements for wireless communication, including between the device and the external environment, and may include on-board processing for control of the electrodes.
