Abstract

A medical implant, in particular a pacemaker, cardioverter, defibrillator or the like, having at least one functional unit (2, 4), such as, for example, an energy storage (2), control electronics (4) or a combination thereof, and a housing (20) for accommodating the at least one functional unit (2, 4). The medical implant furthermore comprises at least one electrode (10), having a connection end (12), an electrode lead (11) and a stimulation end (13), the connection end (12) of the electrode (10) being arranged in the housing (20) for accommodating the at least one functional unit (2, 4).

Claims

1. A cardiac implant, comprising:

at least one functional unit including an energy storage, control electronics or a combination thereof;

a housing for the at least one functional unit; and

at least one electrode having a connection end, an electrode lead and a stimulation end,

the connection end of the electrode being arranged in the housing and being attached directly to the functional unit.

2. A cardiac implant according to claim 1, wherein the housing is configured as a single part.

3. A cardiac implant according to claim 1, wherein the housing comprises at least two housing parts.

4. A cardiac implant according to claim 3, wherein the housing parts have on the inside of the housing at least one structure for assembly of the at least one functional unit.

5. A cardiac implant according to claim 1, wherein the housing is formed of plastic.

6. A cardiac implant according to claim 1, wherein the housing is provided at least in parts with an electrically conductive material.

7. A cardiac implant according to claim 1, wherein the connection end of the electrode is directly connected with the control electronics.

8. A cardiac implant according to claim 7, wherein the connection is carried out by bonding or includes a soldered connection.

9. A cardiac implant according to claim 1, wherein the stimulation end and at least a part of the electrode lead are arranged outside of the housing, and the housing and at least a section of the part of the electrode lead arranged outside of the housing have a sheathing.

10. A cardiac implant according to claim 9, wherein the sheathing comprises a biocompatible material.

11. A cardiac implant according to claim 1, wherein the energy storage comprises an accumulator and/or a capacitor.

12. A cardiac implant according to claim 11, wherein the energy storage is designed to be recharged by high-frequency energy, magnetic-inductive charging, the heat of a patient, chemical energy, mechanical movement or lung movement.

13. A cardiac implant according to claim 1, wherein the control electronics comprise an application-specific integrated circuit.

14. A kit of parts, comprising at least two cardiac implants according to claim 1.

15. A kit of parts according to claim 14, wherein the at least two cardiac implants comprise different designs of the respective stimulation ends.

16. A cardiac implant according to claim 1, wherein the connection end is attached directly to the functional unit by bonding or a soldered connection.

17. A cardiac implant according to claim 5, wherein the housing is formed of polyurethane.

18. A cardiac implant according to claim 10, wherein the sheathing comprises silicone rubber.

19. A cardiac implant according to claim 1, wherein the cardiac implant is a pacemaker, a cardioverter, or a defibrillator.
