1. A minimally invasive implantable medical device for delivering neurostimulation therapy to an acupuncture point for treatment of a symptom associated with the acupuncture point, the implantable medical device comprising:
a hermetically sealed housing formed of a biocompatible metal, the biocompatible metal comprising titanium or an alloy thereof,
the hermetically sealed housing having a reduced size for minimally invasive implantation, with a volume of less than approximately one cubic centimeter,
configured for implantation within a body of a patient for delivery of neurostimulation therapy to an acupuncture point for treatment of a symptom associated with the acupuncture point;
electronic circuitry enclosed within the hermetically sealed housing, electronic circuitry comprising:
a power supply,
a pulse generator,
a memory, and
a control unit configured to cause the pulse generator to deliver a therapy output according to a specified stimulation regimen stored in the memory,
two or more electrodes incorporated into the hermetically sealed housing with externally exposed surfaces capable of being operably positioned in proximity to a targeted nerve and electrically coupled to the pulse generator;
telemetry module and associated antenna configured to establish a wireless telemetry link between the electronic circuitry and at least one external programming device,
wherein communication with the external programming device via the telemetry module enables receipt of a command to adjust an intensity or strength of the therapy up or down,
wherein receipt of a command via the telemetry module is confirmable by the external programming device.
