Abstract
An implantable medical device having a flexible diaphragm is provided with a housing including a shell and an outer layer. The flexible diaphragm extends along the shell. The outer layer has an outer surface and an inner surface. An adhesive coating is applied between the diaphragm and the inner surface of the outer layer. The outer layer includes a recess along the diaphragm for receiving the adhesive.
Claims20
An implantable medical device, comprising:
- a housing having an outer wall and comprising an inner shell and an outer layer formed to extend over and enclose the inner shell to form the outer wall, the outer layer having an inner side engaged against the outer wall of the inner shell and having a thickness extending between the inner side and the outer wall of the housing, wherein the inner shell and the outer layer form a flat portion;
- and
- a flexible diaphragm formed within the inner shell along the flat portion, wherein the outer layer includes a recessed portion formed along a length of the outer layer between the diaphragm and the inner side, wherein the thickness of the outer layer adjacent to the diaphragm is greater than the thickness of the outer layer extending over the diaphragm.
