Abstract

A device for stimulating a living being having proximal end having an 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, at least one electrical stimulation and/or measurement means on the distal end; having distal section having a second outer diameter, which has at least one second dielectric outer envelope and at least one electrical conductor; having 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, wherein said oblong medial section comprises

at least one first dielectric outer envelope,

at least one first electrical conductor configured to reside within said at least one first dielectric outer envelope, and

at least one first electrical stimulation and/or measurement mechanism on a distal area of said oblong medial section wherein said at least one first electrical stimulation and/or measurement mechanism is coupled with said at least one first electrical conductor;

a distal section having a second outer diameter, wherein said distal section is coupled with said oblong medial section and wherein said distal section comprises

at least one second dielectric outer envelope, and

at least one second electrical conductor configured to reside within said at least one second dielectric outer envelope;

a distal end coupled with said distal section, wherein said distal end comprises

at least one second electrical stimulation and/or measurement mechanism wherein said at least one second electrical stimulation and/or measurement mechanism is coupled with said at least one second electrical conductor;

a lumen oriented in a longitudinal direction that passes through at least through the proximal end and said oblong medial section;

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

wherein said at least one first dielectric outer envelope has the same material properties of said at

least one second dielectric outer envelope; and

,

wherein said distal section is configured with a greater flexibility than said oblong medial section

with said at least one second dielectric outer envelope configured with at least one indentation in an inner portion of said at least one second dielectric outer envelope to provide said greater flexibility.

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.

8. The device according to claim 1, wherein said at least one second electrical conductor partially presses internally against said at least one second dielectric outer envelope to increase flexibility of said distal section.

9. 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, wherein said oblong medial section comprises

at least one first dielectric outer envelope,

at least one first electrical conductor configured to reside within said at least one first dielectric outer envelope, and

at least one first electrical stimulation and/or measurement mechanism on a distal area of said oblong medial section wherein said at least one first electrical stimulation and/or measurement mechanism is coupled with said at least one first electrical conductor;

a distal section having a second outer diameter, wherein said distal section is coupled with said oblong medial section and wherein said distal section comprises

at least one second dielectric outer envelope, and

at least one second electrical conductor configured to reside within said at least one second dielectric outer envelope;

a distal end coupled with said distal section, wherein said distal end comprises

at least one second electrical stimulation and/or measurement mechanism wherein said at least one second electrical stimulation and/or measurement mechanism is coupled with said at least one second electrical conductor;

a lumen oriented in a longitudinal direction that passes through at least the proximal end and said oblong medial section;

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

wherein said at least one first dielectric outer envelope and said at least one second dielectric outer envelope are made of a same material; and

,

wherein said distal section is configured with a greater flexibility than said oblong medial section with said at least one second dielectric outer envelope configured with at least one indentation in an inner portion of said at least one second dielectric outer envelope to provide said greater flexibility.

10. The device according to claim 9, 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.

11. The device according to claim 10, 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.

12. The device according to claim 10, 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.

13. The device according to claim 12, wherein said spiral groove runs entirely over said at least one second dielectric outer envelope.

14. The device according to claim 9 wherein said at least one first and said at least one second dielectric outer envelopes are made of silicone.

15. The device according to claim 14, wherein said silicone has a Shore hardness of 30 A.

16. The device according to claim 15, wherein said at least one second electrical conductor partially presses internally against said at least one second dielectric outer envelope to increase flexibility of said distal section.
