Minimally invasive neurostimulation device with sensing capability

A neurostimulation device comprising:

• a header unit comprising:
• at least one primary electrode having a contact surface that defines an external surface of the leadless neurostimulation device;
• and
• a housing comprising:
• a secondary electrode positioned on the same side of the leadless neurostimulation device as the at least one primary electrode;
• a footer coupled to the housing opposite of the header unit;
• a tail lead extending from the footer and comprising one or more sensors;
• and
• a controller configured to operate in a closed-loop to:
• transmit an electrical stimulation signal between the primary electrode to the secondary electrode to provide electrical stimulation therapy to a tibial nerve of a patient;
• measure a physiologic parameter with the one or more sensors in response to transmission of the electrical stimulation therapy;
• and
• adjust one or more parameters of the electrical stimulation signal based on the measured physiologic parameter.
