Abstract

The invention relates a system (302) for medical stimulation. The system (302) comprises an implantable probe (304) bifurcated into a primary branch (306) and a secondary branch (308) at a bifurcation (310), wherein the probe is provided at its distal end (112, 312) with an electrode (114) for delivering electrical stimulation to tissue. Herein, the primary branch (306) is configured for at least temporarily mechanically co-operating with a guide wire (316) configured for guiding the probe (304) into said tissue whereas the secondary branch (308) is configured for electrically connecting said electrode to a device for generating the electrical stimulation.

Claims

1. A system for medical stimulation, comprising:

an implantable probe bifurcated into a primary branch and a secondary branch at a bifurcation,

wherein the probe is provided at its distal end with an electrode for delivering electrical stimulation to tissue, wherein the primary branch is configured for at least temporarily mechanically co-operating with a guide wire configured for guiding the probe into said tissue, and

wherein the secondary branch is configured for electrically connecting said electrode to a device for generating the electrical stimulation.

2. The system according to claim 1, wherein the primary branch is provided at its proximal end with an aperture for receiving the guide wire in a canal configured for accommodating said guide wire.

3. The system according to claim 2, wherein the canal extends beyond the bifurcation.

4. The system according to claim 2, further comprising an electrical wire spiraling around the canal for electrically connecting the electrode to the device.

5. The system according to claim 2, wherein the canal is closable.

6. The system according to claim 2, wherein the canal is closable by a blocking material injectable in the aperture.

7. The system according to claim 2, wherein the canal is closable by a plug installable in the aperture.

8. The system according to claim 2_s wherein the primary branch is configured for being ligatured for closing the aperture.

9. The system according to claim 1, wherein a distance between a proximal end of the secondary branch and the bifurcation is substantially larger than a distance between the proximal end of the primary branch and the bifurcation.

10. The system according to claim 1, wherein the device is installable in an implantable box.

11. The system according to claim 10, wherein the box comprises an electrical connector for releasably electrically co-operating with a further electrical connector situated at a proximal end of the secondary branch.
