Abstract
A monolithic implantable medical device component includes multiple portions on a single substrate. The portions can be electrically connected to an electronics module, which may include output connectors and input connectors to and from the various portions of the substrate. A portion of the monolithic component to be disposed within, attached to, embedded in, or otherwise combined with a magnet retention feature, such as a plate.
Claims25
An implantable medical device, comprising:
- a monolithic implantable component, comprising:
- a substrate comprising a telemetry coil region, an electrical interface region, and an elongate anatomy interface region;
- a coil disposed within the substrate at the telemetry coil region;
- one or more connectors formed on the electrical interface region, wherein the telemetry coil region extends from a first side of the electrical interface region in a first direction along an axis;
- and
- a plurality of electrodes formed on the elongate anatomy interface region, wherein the plurality of electrodes is formed in a linear array, wherein the elongate anatomy interface region is configured as to be inserted into a cochlea of a recipient for positioning of the plurality of electrodes for stimulation of the recipient's auditory nerves from within the cochlea, and wherein the elongate anatomy interface region extends from a second side, opposite the first side, of the electrical interface region in a second direction, opposite the first direction, along the axis such that the telemetry coil region, the electrical interface region, and the elongate anatomy interface region are offset from one another along the axis;
- and
- an electronics module external to the substrate, wherein the electronics module comprises a conductor configured to electrically connect to the one or more connectors of the monolithic implantable component.
5 more elements
An implantable medical device, comprising:
- a telemetry coil disposed within a substrate;
- an electrical interface region formed on the substrate, wherein the electrical interface region comprises segments that are offset from one another to form a space therebetween;
- an anatomy interface region formed on the substrate, wherein the anatomy interface region includes one or more electrodes disposed thereon,
- wherein the telemetry coil, the electrical interface region, and the anatomy interface region are integrated via the substrate;
- and
- an electronics module external to the substrate, wherein the electronics module comprises a conductor configured to directly connect to the electrical interface region, and wherein the electronics module is configured to be positioned against the segments of the electrical interface region to be positioned over and extend across the space between the segments.
3 more elements
A method of manufacturing an implantable medical component comprising:
