초록 ▼

One aspect relates to an electrical bushing for use in a housing of an implantable medical device. The electrical bushing includes at least one electrically insulating base body and at least one electrical conducting element. The conducting element is set-up to establish, through the base body, at least one electrically conductive connection between an internal space of the housing and an external space. The conducting element is hermetically sealed with respect to the base body. The at least one conducting element includes at least one cermet. The cermet has a metal fraction in a range from 30% by volume to 60% by volume.

대표청구항 ▼

1. A method for the manufacture of an electrical bushing for an implantable medical device, the method comprising: a. generating at least one base body green compact for at least one base body from an insulating composition of materials;b. forming at least one cermet-containing conducting element green compact for at least one conducting element;c. introducing the at least one conducting element green compact into the base body green compact;d. connecting the base body green compact to the at least one conducting element green compact in order to obtain at least one base body having at least one conducting element;whereby, step a) or step b) include at least a partial forming of the respective green compact by introducing a base mass of the respective green compact into a forming tool at a pressure in the range from 0.1 MPa to 50 MPa whereby the method comprises the following steps preceding step d):producing a cermet-containing holding element green compact for a holding element;introducing the at least one conducting element green compact into the base body green compact, and introducing the base body green compact into the holding element green compact;whereby step d) comprises:firing the insulating element green compact jointly with the at least one conducting element green compact and the holding element green compact in order to obtain a base body having at least one conducting element and a holding element. 2. The method according to claim 1, whereby the base mass has a viscosity in a range from 103 to 1013 mPas. 3. The method according to claim 1, whereby step d) is carried out through at least partial sintering of the conducting element green compact and the base body green compact. 4. The method according to claim 1, whereby the surface of the electrical bushing is polished at least in part. 5. The method according to claim 1, whereby the at least one conducting element comprises at least one electrically conductive connecting layer. 6. The method according to claim 5, whereby step b) comprises a partial sintering of the conducting element green compact. 7. The method according to claim 1, whereby step a) comprises a partial sintering of the base body green compact. 8. The method according to claim 1, whereby producing the cermet-containing holding element green compact comprises a partial sintering.
