Abstract

A device for stimulating a living being having a proximal end having means for the electrical connection to an implantable medical device; having an oblong medial section having a first external diameter, which has at least one first dielectric outer envelope, at least one electrical conductor, and at least one electrical stimulation and/or measurement means on the distal end; having a distal section having a second outer diameter, which has at least one second dielectric outer envelope and at least one electrical conductor; having a distal end having at least one electrical stimulation and/or measurement means; and having a lumen running in the longitudinal direction at least through the proximal end and the medial section. The first external diameter is isodiametric to the second external diameter, the first dielectric outer envelope has the same material properties as the second dielectric outer envelope, and the medial section has a lesser flexibility than the distal section.

Claims

1. A device for electrostimulation comprising:

a proximal end configured for electrical connection to an implantable medical device;

an oblong medial section having a first external diameter, having at least one first dielectric outer envelope, having at least one electrical conductor and at least one electrical stimulation and/or measurement mechanism on its distal end;

a distal section having a second outer diameter, having at least one second dielectric outer envelope, and having at least one electrical conductor;

a distal end having at least one electrical stimulation and/or measurement means;

a lumen running in the longitudinal direction at least through the proximal end and said medial section wherein

said first external diameter is isodiametric to said second outer diameter;

wherein said at least one first dielectric outer envelope has material properties of said at least one second dielectric outer envelope; and

,

said distal section configured with a greater flexibility than said medial section.

2. The device according to claim 1, wherein said at least one second dielectric outer envelope has at least one section which has a lesser wall thickness than said at least one first dielectric outer envelope.

3. The device according to claim 2, wherein said at least one section of said at least one second dielectric outer envelope comprises at least one annular groove in an inner wall of said at least one second dielectric outer envelope.

4. The device according to claim 2, wherein said at least one section of said at least one second dielectric outer envelope comprises at least one spiral groove in an inner wall of said at least one second dielectric outer envelope.

5. The device according to claim 4, wherein said spiral groove runs entirely over said at least one second dielectric outer envelope.

6. The device according to claim 1 wherein said at least one first and said at least one second dielectric outer envelopes are made of silicone.

7. The device according to claim 6, wherein said silicone has a Shore hardness of 30 A.
