Abstract

The disclosure relates to an implant comprising a housing, in which there are arranged an energy store and an electronics module, wherein a feedthrough to an electrode connection device is formed on the housing, wherein a first contact forms an electrical connection between the energy store and the electronics module, wherein a second contact forms an electrical connection between the electronics module and the feedthrough, and wherein the first contact and the second contact are oriented in the same contact direction. A method for assembling an implant is also disclosed.

First claim

The invention claimed is:

1. An implant comprising:
a housing,
an energy store and an electronics module arranged in the housing,
a feedthrough to an electrode connection device formed on the housing,
a first contact forming an electrical connection between the energy store and the electronics module, and
a second contact forming an electrical connection between the electronics module and the feedthrough,
wherein the first contact and the second contact are oriented in the same contact direction,
wherein the energy store, the electronics module, and the feedthrough are arranged one above the other in a stacking direction, wherein the stacking direction corresponds to the contact direction, and
wherein the electronics module has a planar substrate, the planar substrate being parallelly arranged on a front side of the energy store.

2. The implant according to claim 1 , wherein the first contact is formed between a first pin element and a first pin receptacle, wherein a longitudinal extension of the first pin element determines the contact direction.

3. The implant according to claim 1 , wherein the second contact is formed between a second pin element and a second pin receptacle, wherein a longitudinal extension of the second pin element defines the contact direction.

4. The implant according to claim 1 , wherein the electronics module is arranged in a support frame.

5. The implant according to claim 4 , wherein the support frame is arranged in the housing in such a way that the energy store is fixed by the support frame, and/or wherein the support frame is designed and arranged in the housing in such a way that the support frame reduces or prevents a relative movement between the energy store and the electronics module.

6. The implant according to claim 1 , wherein the housing is formed in two parts and has a first housing shell and a second housing shell.

7. The implant according to claim 6 , wherein the energy store is fixed between the first housing shell and the second housing shell.

8. The implant according to claim 1 , wherein the energy store is fastened to the housing.

9. A method for assembling an implant, comprising the following steps:
providing an energy store,
providing an electronics module having a planar substrate,
providing a feedthrough,
arranging the electronics module on the energy store such that the planar substrate is parallelly arranged on a front side of the energy store, and
arranging the feedthrough on the electronics module,
wherein the feedthrough, the electronics module, and the energy store are arranged on top of each other along a common assembly direction,
providing a first contact forming an electrical connection between the energy store and the electronics module, and
providing a second contact forming an electrical connection between the electronics module and the feedthrough,
wherein the first contact and the second contact are oriented in the same contact direction, and
wherein the common assembly direction corresponds to the contact direction.
