Abstract
Described herein are methods and devices for monitoring or modulating an immune system in a subject with cancer, and methods and devices for treating a cancer in a subject. The implanted device can electrically stimulate the splenic nerve of the subject, which can modulate the inflammatory system (for example, by increasing or decreasing the blood level of one or more pro-inflammatory cytokines and/or anti-inflammatory cytokines to increase or decrease inflammation in the subject) and/or activate or increase circulation of one or more immune cells (such as natural killer cells and/or cytotoxic T-cells), for the treatment of cancer. The implanted medical device includes two or more electrodes configured to electrically stimulate the splenic nerve, and may further include an ultrasonic transducer configured to receive ultrasonic waves and convert energy from the ultrasonic waves into an electrical energy that powers the device.
