Implantable device-based peripheral edema status monitoring

A method of determining a peripheral edema status of a patient, the method comprising:

• sensing, via an implantable medical device (IMD) configured for subcutaneous implantation proximate a lymphatic element of a patient, an impedance signal indicative of one or more physiological parameters of the lymphatic element;
• determining, via processing circuitry, the one or more physiological parameters of the lymphatic element based on the impedance signal;
• determining, via the processing circuitry, a peripheral edema status of the patient based on the one or more physiological parameters;
• and
• outputting, via the processing circuitry, an indication of the peripheral edema status.

A computer readable medium storing instructions that when executed by one or more processors cause the one or more processors to perform:

• sensing, via an implantable medical device (IMD) configured for subcutaneous implantation proximate a lymphatic element of a patient, an impedance signal indicative of one or more physiological parameters of the lymphatic element;
• determining the one or more physiological parameters of the lymphatic element based on the impedance signal;
• determining a peripheral edema status of the patient based on the one or more physiological parameters;
• and
• outputting an indication of the peripheral edema status.
