Abstract
An implantable prosthesis, including an implantable component including an implantable magnet assembly, wherein the magnet assembly includes a magnet plated with a metallic substance, the magnet assembly includes a housing made at least in part of a polymer, wherein at least a portion of the housing made out of the polymer is in direct contact with the metallic substance, and the implantable component is configured to be implanted in a human such that the housing is exposed to body fluids thereof.
Claims31
An implantable prosthesis, comprising:
- an implantable component including an implantable magnet assembly, wherein
- the magnet assembly includes a magnet plated with a metallic substance,
- the magnet assembly includes a housing made at least in part of a polymer, wherein the magnet is located in the housing, wherein at least a portion of the housing made out of the polymer is in direct contact with the metallic substance, and
- the implantable component is configured to be implanted in a human such that the housing is exposed to body fluids thereof.
An implantable prosthesis, comprising:
- an implantable functional component including an implantable first housing and an implantable magnet assembly, the first housing having electronics located therein, wherein
- the magnet assembly includes a plated magnet located in a second housing,
- the second housing is established by structural components that are carbon or silicone chain based components, and
- the magnet assembly includes only one housing, the only one housing corresponding to the second housing.
An implantable magnet assembly, comprising:
- a magnet coated with a substance, the magnet being located in a housing, wherein
- the implantable magnet assembly is configured to be implanted in a human such that the housing is exposed to body fluids thereof, and
- the assembly is configured to protect the magnet from body fluids via a system that consists of the substance that coats the magnet and one or more non-metallic pliable components.
A method, comprising:
- establishing or breaking a magnetic attractive field between a first magnet of an external component of a prosthesis and a second magnet of an implanted component of the prosthesis, a portion of a magnetic path of the magnetic attractive field between the first magnet and the second magnet that extends through the recipient to the second magnet passing though at most only carbon based substances, silicon based substances, air, and water based substances, in addition to also passing through a metallic coating of the second magnet.
