Abstract

An implantable medical device including a housing, an electrical circuit unit, and a feedthrough component, which is electrically connected to at least one contact of the electrical circuit unit, wherein the device further comprises a support fixedly connected to the electrical circuit unit. In order to reduce the number of steps during manufacturing, in particular, for the device with a sleeve-type housing, the support provides at least one fixture element adapted for a mechanical fixing of the feedthrough component relative to the electrical circuit unit within the housing. The disclosure further refers to a respective manufacturing method.

First claim

I/We claim:

1 . An implantable medical device comprising:
a housing; an electrical circuit unit; a feedthrough component, which is electrically connected to at least one contact of the electrical circuit unit; and a support fixedly connected to the electrical circuit unit, wherein the support provides at least one fixture element adapted for a mechanical fixing of the feedthrough component relative to the electrical circuit unit within the housing.

2 . The implantable medical device according to claim 1 , wherein the at least one fixture element is a form-fit element comprising a staking pin, cooperating with a respective form-fit element comprising a through going opening, of a bracket of the feedthrough component.

3 . The implantable medical device according to claim 1 , wherein the at least one fixture element is accommodated in the clearance between the electrical circuit unit and the housing parallel to the feedthrough component.

4 . The implantable medical device according to claim 1 , wherein the support is formed as a frame and adapted to carry a passive electronic comprising an antenna.

5 . The implantable medical device according to claim 4 , wherein the bracket of the feedthrough component comprises an L-form, wherein a first arm of the L runs perpendicular to the extension of the electrical circuit unit, and a second arm of the L comprises the form-fit element and runs parallel to the extension of the electrical circuit unit.

6 . The implantable medical device according to claim 1 , wherein the electrical circuit unit comprises an interconnect weld ribbon and the feedthrough component comprises at least one tab for electrical connection.

7 . The implantable medical device according to claim 5 , wherein the electrical circuit unit comprises a flex arm extension for electrical connection with the feedthrough component.

8 . A manufacturing method for an implantable medical device comprising a housing, an electrical circuit unit, a feedthrough component and a support, the method comprising the following steps:
fixedly connecting of the electrical circuit unit with the support; mechanical fixing of the feedthrough component relative to the electrical circuit unit by means of at least one fixture element provided at the support; forming an electrical connection of the feedthrough component with at least one contact of the electrical circuit unit; and placing the assembly comprising the support with the electrical circuit unit and the feedthrough component within the housing and hermetically sealing the housing.

9 . The method according to claim 8 , wherein for mechanical fixing of the feedthrough component by means of the at least one fixture element provided at the support, the fixture element of the support is form-fit connected to a corresponding fixture element at the feedthrough component and preferably thereafter fixed by a material engagement.

10 . The method according to claim 9 , wherein prior to the connection of the electrical circuit unit with the support, a passive electronic module comprising an antenna is attached to the support.
