Abstract
A medical device prosthesis, including a housing and a piezoelectric transducer including a piezoelectric component, wherein the piezoelectric transducer is supported in the housing via at least one spring. In some embodiments, the medical device prosthesis is a bone conduction device, such as a transcutaneous passive or active bone conduction device.
Claims30
A prosthetic medical device, comprising:
- a housing;
- and
- a piezoelectric component, wherein
- the piezoelectric component is supported in the housing via at least one spring.
1 more element
A component of a bone conduction device, comprising:
- a housing;
- and
- a transducer-seismic mass assembly, wherein
- the component is configured to enable permanent shock-proofing of the assembly beyond that which results from damping.
1 more element
A bone conduction device, comprising:
- a housing;
- and
- a transducer-seismic mass assembly including a piezoelectric component, wherein
- the transducer-seismic mass assembly of the bone conduction device is configured to translate in its entirety within the housing when the housing is closed.
1 more element
A method, comprising:
- obtaining a component of a medical device prosthesis including a piezoelectric bender;
- operating the component in a first mechanical state such that the piezoelectric bender bends in a manner that at least one of consumes or generates electricity, wherein
- the component is configured to experience an acceleration of 30 Gs in the first mechanical state in both directions normal to a plane of extension of the piezoelectric bender and subsequently operate in the first mechanical state.
