1. An implantable medical device, comprising:
- a housing;
an ultrasonic transducer disposed within an interior of the housing, the ultrasonic transducer configured to communicate at a frequency at or near a resonance frequency of the housing; and
a limiting structure secured to the ultrasonic transducer, the limiting structure configured to constrain deformation of the ultrasonic transducer and transfer acoustic energy from the ultrasonic transducer to a resonant region of the housing, wherein the resonant region of the housing is defined by the limiting structure.

Abstract
Implantable medical devices including an ultrasonic transducer and methods of optimizing an ultrasonic transducer of an implantable medical device are disclosed. The implantable medical device can include a housing, an ultrasonic transducer disposed within an interior of the housing, and a limiting structure configured to constrain deformation of the ultrasonic transducer. The limiting structure can include a separate structure coupled to the housing, or can comprise a resonant portion of the housing itself. During operation, the ultrasonic transducer is configured to communicate at a frequency at or near a resonant frequency of the housing.
