Abstract

An external charger for an implantable medical device, comprises a housing, an alternating current (AC) coil and substrate contained within the housing, and one or more electronic components mounted to the substrate. The AC coil is configured for wirelessly transmitting magnetic charging energy to the implantable medical device. The AC coil is disposed in a first plane, with the magnetic charging energy having a field directed perpendicular to the first plane. At least a portion of the substrate has a surface extending along a second plane that is substantially perpendicular to the first plane.

First claim

What is claimed is:

1. An external charger for an implantable medical device, comprising:
a housing;
an alternating current (AC) coil disposed within a first plane within the housing, the AC coil configured for wirelessly transmitting magnetic charging energy to the implantable medical device;
a substrate contained within the housing, at least a portion of the substrate having a surface extending along a second plane in a non-parallel relationship with the first plane; and
one or more electronic components mounted to the surface of the substrate,
wherein the at least a portion of the substrate is located outside of an area within a perimeter of the coil projected in directions perpendicular to the first plane.

2. The external charger of claim 1 , wherein the second plane forms an angle with the first plane equal to or greater than forty-five degrees.

3. The external charger of claim 1 , wherein the second plane is perpendicular to the first plane.

4. The external charger of claim 1 , wherein the substrate comprises a printed circuit board (PCB).

5. The external charger of claim 1 , further comprising an energy source contained within the housing, wherein the charging energy is derived from the energy source.

6. The external charger of claim 1 , wherein the one or more electronic components perform a signal processing function.

7. The external charger of claim 1 , wherein the entirety of the substrate extends along the second plane.

8. An external charger for an implantable medical device, comprising:
a housing;
an alternating current (AC) coil disposed in a first plane within the housing, the AC coil configured for wirelessly transmitting magnetic charging energy to the implantable medical device; and
a plurality of electronic components contained within the housing, the plurality of components arranged along a second plane that is substantially perpendicular to the first plane wherein at least a portion of the plurality of electronic components is located outside of an area within a perimeter of the coil projected in directions perpendicular to the first plane.

9. The external charger of claim 8 , further comprising an energy source contained within the housing, wherein the charging energy is derived from the energy source.

10. The external charger of claim 8 , wherein the plurality of components is configured for performing one or more signal processing functions.
