Abstract
Disclosed herein, among other things, is a system for electrical stimulation of blood vessels. An embodiment of the system includes at least one electrode having electrical contact with a blood vessel. The embodiment also includes a stimulation circuit electrically connected to the electrode, the circuit adapted to provide stimulation to the vessel. The embodiment further includes a controller connected to the circuit, the controller adapted to select frequency and voltage parameters for the stimulation circuit to selectively affect vascular therapy, including constriction of the vessel and dilation of the vessel. According to various embodiments, the stimulation circuit and controller are contained within an implantable medical device (IMD). The system also includes a sensor connected to the controller, and the controller initiates and adjusts therapy based on a signal received from the sensor, in varying embodiments.
