Package for an implantable medical device
View Patent ↗The present invention is an implantable electronic device formed within a biocompatible hermetic package. Preferably the implantable electronic device is used for a visual prosthesis for the restoration of sight in patients with lost or degraded visual function. The package may include a hard hermetic box, a thin film hermetic coating, or both.
1. A visual prosthesis comprising:
an internal electronics unit, suitable for implantation within a living body, at least a portion of said internal electronics unit is formed within a biocompatible hermetic box including a metal portion braised to a ceramic portion; and
a plurality of electrodes driven by said internal electronics unit suitable for stimulating visual neurons to create a perception of a visual image.
2. The visual prosthesis according to claim 1 wherein said internal electronics unit is suitable to be implanted in the vicinity of the eye.
3. A visual prosthesis comprising:
an internal electronics unit, suitable for implantation within a living body, at least a portion of said internal electronics unit is formed within a biocompatible hermetic box including a metal portion and a ceramic portion;
a flip chip electrically connected to feed-throughs in said ceramic portion; and
a plurality of electrodes driven by said internal electronics unit suitable for stimulating visual neurons to create a perception of a visual image.
4. The visual prosthesis according to claim 3 wherein said internal electronics unit is suitable to be implanted in the vicinity of the eye.
5. A visual prosthesis comprising:
an internal electronics unit, suitable for implantation within a living body, at least a portion of said internal electronics unit is formed within a biocompatible hermetic box including a metal portion and a ceramic portion;
a plurality of electrodes driven by said internal electronics unit suitable for stimulating visual neurons to create a perception of a visual image;
wherein said metal portion includes a metal sidewall joined with a metal top by a weld joint.
6. The visual prosthesis according to claim 5 wherein said internal electronics unit is suitable to be implanted in the vicinity of the eye.
