Housing for an implantable medical device
First Claim
1. An implantable medical device comprising:
- a housing comprising a front side and an opposing back side defining an interior chamber disposed between the front and back sides, wherein the front side comprises a substantially-planar metal portion and an opening passing through the front side to communicate with the interior chamber;
a ceramic window disposed in the opening;
a printed circuit board disposed in the interior chamber and comprising electronic components positioned between the substantially-planar metal portion and the back side; and
an electronic trans-housing magnetic flux component disposed within the interior chamber between the ceramic window and the back side, said magnetic flux component being configured to be magnetically coupled to an external flux component via a magnetic field passing through the ceramic window.

Abstract
An implantable medical device having a concave ceramic housing component; a concave metal housing component attached to the ceramic housing component to form a hermetically sealed enclosure; and an electronic trans-housing magnetic flux component disposed within the enclosure. Another aspect of the invention provides an implantable medical device having a ceramic housing component; a metal housing component; a circumferential sealing member attached to a periphery of the ceramic housing component and to a periphery of the metal housing component to form a hermetically sealed enclosure; and an electronic trans-housing magnetic flux component disposed within the enclosure. Still another aspect of the invention provides an implantable medical device with a first metal housing component; a second metal housing component, the second metal housing component forming an opening; a ceramic housing component disposed in the opening, the first metal housing component, the second metal housing component and the ceramic housing component cooperating to form a hermetically sealed enclosure; and an electronic trans-housing magnetic flux component disposed within the enclosure.

15. An implantable medical device configured to receive energy from a primary coil disposed at a position external to the medical device, the device comprising:
-
a metal housing component defining an interior chamber and having a metal opening edge defining an opening communicating with the interior chamber; a secondary coil; and a printed circuit board supporting the secondary coil disposed within the interior chamber to position the secondary coil adjacent to the opening to receive energy from the primary coil when the primary coil is disposed at the position external to the medical device, wherein a portion of the printed circuit board supporting the secondary coil fully occludes the opening as viewed from the position external to the medical device. - View Dependent Claims (16, 17, 18)
