A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Minimally invasive implantable neurostimulation system

In some examples, an assembly for a medical device. The assembly includes a first electrode comprising a first conductive tab, and a first current collector; a second electrode including a second conductive tab, a second current collector, a third current collector, and at least one connector connecting the second current collector to the third current collector, wherein the second current collector and the third current collector are folded over each other about the at least one connector, wherein the second conductive tab is coupled to the second current collector, and wherein the third current collector is electrically coupled to second conductive tab via the at least one connector and the second current collector; and a foil package being sealed over the first conductive tab and the second conductive tab to partially enclose the first electrode and second electrode.

Battery assembly

A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site.
