Abstract

An implantable device for implantation in a human body or animal body. The device includes an energy source, an energy storage device, and an electronics unit. Further, an actuator is coupled with the energy storage device and it is configured to emit electromagnetic waves by discharging the energy storage device.

First claim

The invention claimed is:

1. A device, comprising:
an energy source;
an energy storage device;
an electronics unit;
an actuator connected to said energy storage device and configured to emit electromagnetic waves by discharging the energy storage device;
said electronics unit including a controller configured to adjust at least two impedances that are connected in series, said discharging taking place over said at least two series-connected impedances; and
wherein said at least two series-connected impedances are electrical switches.

2. The device according to claim 1 configured for implantation in a human or animal body.

3. The device according to claim 1 , wherein said actuator is configured to at least one of detect or evoke action potentials in genetically manipulated tissue by emitting electromagnetic waves in a frequency range of 10 13 -10 20 Hz.

4. The device according to claim 1 , wherein said energy storage device has at least one of a capacitor or a coil.

5. The device according to claim 1 , wherein the discharge takes place in more than one phase.

6. The device according to claim 1 , wherein said actuator has at least one of the following properties:
said actuator comprises at least one light source for emitting the electromagnetic waves;
said actuator comprises at least one current limiter;
said actuator is supplied by said energy storage device at a voltage between 1 V and 1,500 V;
said actuator is arranged separately from a housing of the device and has a plug-and-socket connector, which is compatible with a plug socket of an implantable device for electrical cardiac stimulation.

7. The device according to claim 6 , wherein said actuator comprises said at least one light source for emitting the electromagnetic waves, said at least one light source including a series circuit of LEDs, or a parallel circuit of LEDs, or a combination of a series circuit and a parallel circuit of LEDs.

8. The device according to claim 6 , wherein said actuator comprises said at least one light source for emitting the electromagnetic waves, said at least one light source including a laser light source.

9. The device according to claim 1 , further comprising a telemetry unit with at least one of an external device or an external data center.

10. An implantable stimulation device, comprising a device according to claim 1 for a stimulation of cardiac tissue or nerve tissue structures.

11. The implantable stimulation device according to claim 10 , further comprising at least one stimulation electrode.

12. The implantable stimulation device according to claim 10 , configured to cause the stimulation of the cardiac tissue, the stimulation comprising at least one of the following:
stimulation by way of the actuator by electromagnetic waves; or
stimulation by electrical stimulation;
wherein the stimulation by electromagnetic waves and by electrical stimulation is effected individually, consecutively, or simultaneously; and
wherein the stimulation is effected in one area or in multiple areas of the tissue.

13. The implantable stimulation device according to claim 10 , further comprising at least one of:
a plug contact that is compatible with an actuator according to claim 1 ; or
a plug contact that is compatible with an electrode for electrical stimulation; or
an actuator and an electrode.
