Resonant structures for implantable devices
First Claim
1. An implantable medical device comprising:
- a housing having an inside adapted to contain control circuitry of the implantable medical device;
an annular shaped limiting structure disposed within the inside of the housing and defining a resonant region in the housing; and
an acoustic transducer connected directly to the limiting structure within the inside of the housing, the acoustic transducer extending into the resonant region so that the resonant region mechanically amplifies the deformation of the acoustic transducer at a resonant frequency.

Abstract
An implantable medical device comprising a housing and a limiting structure defining a resonant region in the housing. An acoustic transducer is connected to the limiting structure and extends into the resonant region so that the resonant region mechanically amplifies the deformation of the acoustic transducer at a resonant frequency. An implantable medical device comprising a housing and a limiting structure defining a resonant region in the housing. An acoustic transducer having the shape of a beam is mechanically coupled to the limiting structure and partially extends into the resonant region so that the resonant region mechanically amplifies the deformation of the acoustic transducer at a resonant frequency. An implantable medical device comprising a housing, an acoustic transducer coupled to the housing, and a means for mechanically amplifying the deformation of the acoustic transducer at a resonant frequency. The means defines a resonant region in the housing.
