Stackable capacitor for an implantable medical device

1 . A capacitor assembly, comprising:

three structurally identical capacitors, each of said structurally identical capacitors containing:

a housing having a first outer side, a second outer side facing away from said first outer side, and a lateral outer side running in a circumferential direction of said housing, said first and second outer sides being connected to one another via said lateral outer side running in the circumferential direction of said housing, said lateral outer side having a straight first portion and an arcuate second portion, said straight first portion having a middle region and two end regions, which are connected to one another via said middle region of said straight first portion, and said end regions are each connected to said arcuate second portion; and

an electrical terminal disposed on said middle region of said straight first portion of said lateral outer side, said electrical terminal having two planar contact surfaces for electrically contacting said capacitor;

said arcuate second portion of said lateral outer side forming, with said first outer side, a rounded housing edge of said housing of the capacitor;

a substantially flat wiring strip including a plurality of conductor tracks being connected to the electrical terminals of said three structurally identical capacitors;

said structurally identical capacitors being disposed stacked one above the other so that each of said structurally identical capacitors contacts with said first outer side or via said second outer side said first outer side or said second outer side of an adjacent one of said structurally identical capacitors of the capacitor assembly;

said structurally identical capacitors including a first outer capacitor, a second middle capacitor, and a third outer capacitor, said second middle capacitor being disposed between said first and third outer capacitors, said second middle capacitor contacting with said second outer side of said third outer capacitor, and said second middle capacitor contacts with said first outer side or said second outer side of said first outer capacitor; and

said electrical terminal of said third outer capacitor being disposed offset relative to said electrical terminal of said first outer capacitor and said second middle capacitor of the capacitor assembly.

2 . The capacitor assembly according to claim 1 , wherein said housing is symmetrically identical with respect to a plane of symmetry, which runs perpendicularly to said straight first portion of said lateral outer side and perpendicularly to said first outer side and said second outer side.

3 . The capacitor assembly according to claim 1 , wherein said first outer side and/or said second outer side is semi-circular.

4 . The capacitor assembly according to claim 1 , wherein the capacitors are electrolytic capacitors.

5 . The capacitor assembly according to claim 1 , wherein the first portion of the lateral outer side has a center point in the circumferential direction, and in that the electrical terminal has a center point in the circumferential direction, and the center point of the electrical terminal in the circumferential direction is disposed offset relative to the center point of the first portion.

6 . An implantable medical device, comprising:

a device housing surrounding an interior, wherein said device housing having an arcuate inner side;

a capacitor assembly according to claim 1 disposed in said interior; and said second portion of said lateral outer side of said housing of each of said capacitors extending along said arcuate inner side of said device housing.
