Abstract
An electrode device for active medical implants that includes an elongated electrode body having a proximal end and a distal end, a tip contact pole on the distal end and/or a ring contact pole before the distal end, electrical supply leads to the tip and ring contact poles, and a high-frequency filter in at least one of the supply leads, which is composed of one or more electronic components (9) and is assigned to the tip and/or ring contact pole, wherein the electronic component(s) (9) are each designed as a miniature component using LTCC technology.
Claims13
An electrode device for active medical implants, comprising:
- an elongated electrode body having a proximal end and a distal end;
- a tip contact pole on the distal end and/or a ring contact pole proximal to the distal end;
- electrical supply leads to the tip and ring contact poles;
- one or more electronic components;
- a high-frequency filter in at least one of the electrical supply leads, which comprises said one or more electronic components and is associated with the tip and/or ring contact pole;
- and,
- wherein the one or more electronic components comprises a miniature component comprising LTCC technology;
- wherein the high-frequency filter comprises a capacitor and/or a coil comprising LTCC technology;
- wherein the coil is configured as a sandwich composed of open metal rings and ceramic layers stacked on top of one another in alternation, wherein adjacent metal rings are electrically connected at their respective open ends by way of passages;
- wherein said metal rings are formed of flat material in the shape of annular disks, disposed parallel to one another and overlapping in a stacking direction;
- and
- wherein said metal rings overlapping in a stacking direction comprise one or more gaps between said open ends of said metal rings, which extend by a few circumferential degrees around said metal rings, and are offset from one another in the peripheral direction such that they do not overlap.
