Abstract

A medical implant comprising a transducer element which induces mechanical vibrations of the implant when electrically and/or magnetically controlled.

Claims

1. A medical implant comprising:

a transducer element which induces mechanical vibrations of the implant when electrically and/or magnetically controlled.

2. The implant according to claim 1, wherein the transducer element comprises a transducer element coupling inductively to an alternating magnetic field.

3. The implant according to claim 1, wherein the transducer element comprises an electrically controllable transducer element.

4. The implant according to claim 1, wherein the transducer element is in the form of an oscillating body inserted separately into the implant.

5. The implant according to claim 1, wherein the transducer element is disposed in a wall region of the implant and embedded in the wall region over a large surface area.

6. The implant according to claim 3, wherein the transducer element comprises a piezoceramic foil or a piezoelectric polymer foil.

7. The implant according to claim 1, further comprising an electrical connection for the contacting of the transducer element using a temporary control line serving as an explantation aid.

8. The implant according to claim 1, further comprising an integrated control line for connection to an internal control device, a control device disposed in a further implant, or an extracorporeal control device.

9. The implant according to claim 1, wherein the transducer element is designed, or additional energy supply means are provided, for wireless control by way of an extracorporeally generated electromagnetic alternating field.

10. The implant according to claim 9, wherein the implant further comprises a receive coil device which is inserted into the transducer element or is connected thereto.

11. The implant according to claim 1, which is in the form of an implantable electrode lead or sensor lead.

12. The implant according to claim 11, wherein a piezoceramic foil or a piezoelectric polymer foil, in sleeve form or annular segment form, is disposed in or on the wall of a distal section.

13. The implant according to claim 1, which is in the form of a leadless cardiac stimulation or cardioversion device or as a leadless sensor.

14. The implant according to claim 13, wherein a piezoceramic foil or a piezoelectric polymer foil, in sleeve form or annular segment form, is disposed in or on the wall of a distal section.

15. A medical arrangement comprising:

an implant according to claim 1; and

a control device for the electrical and/or magnetic control of the transducer element and coupling means for coupling energy therein.

16. The arrangement according to claim 15, wherein the control device is in the form of an extracorporeal explantation support device.
