Abstract

In one aspect, the present disclosure is directed to an implantable medical device including a housing having a generally planar portion, and a piezoelectric transducer disposed within the housing, wherein at least a portion of the piezoelectric transducer is arranged at an oblique angle to the generally planar portion of the housing, and an electrode to deliver a neurostimulation therapy. The implantable medical device is configured to receive energy signals from an external device and transduce the received energy signals into electrical power.
