Abstract

An implantable curved shaping part for externally shaping an implantable electrode line or a catheter, wherein the shaping part has a continuous first lumen to allow a portion of the electrode line or of the catheter to pass through, wherein the shaping part has an extruded tube formed from two materials, each coextruded over a predetermined wall segment, having different shrinkage behavior or has a portion of an extruded spiral tube, wherein one of the coextruded materials or the material of the spiral tube has a high Shore hardness, in particular, of 60 Shore or more.

First claim

We claim:

1. An implantable curved shaping part for externally shaping an implantable electrode line or a catheter, wherein the shaping part has a continuous first lumen to allow a portion of the electrode line or of the catheter to pass through, wherein the shaping part has an extruded tube formed from two materials, each coextruded over a predetermined wall segment, having different shrinkage behavior or has a portion of an extruded spiral tube, wherein one of the coextruded materials or the material of the spiral tube has a high Shore hardness of 60Shore or more.

2. The shaping part according to claim 1 , formed as a part that is U shaped or V shaped in the use state with rounded tip.

3. The shaping part according to claim 1 , which has a silicone tube or silicone tube portion.

4. The shaping part according to claim 1 , having ends that are overmolded with a material of lower Shore hardness of 40 Shore or less, whereby lumen end portions are formed that have a widened diameter, such that space for an inner adhesive layer is created.

5. The shaping part according to claim 1 , wherein the coextruded materials of the extruded tube each occupy a semi-cylindrical wall segment.

6. An electrode line arrangement having an implantable electrode line and at least one shaping part according to claim 1 , which surrounds a distal portion of the electrode line.

7. The electrode line arrangement according to claim 6 , wherein the shaping part completely surrounds a portion between two electrode poles in such a way that a first end of the shaping part directly contacts a first electrode pole and a second end of the shaping part directly contacts a second electrode pole.

8. The electrode line arrangement according to claim 6 , wherein two or more U shaped or V shaped shaping parts are arranged in succession in the longitudinal direction on the electrode line optionally with oppositely directed curvature, such that a distal end portion of the electrode line on the whole has a substantially S-shaped, Z-shaped, J-shaped, undulating or zigzagged profile.

9. A catheter arrangement having a catheter and at least one shaping part according to claim 1 .

10. The shaping part according to claim 1 , wherein the two different coextruded materials of the extruded tube each occupy an angular portion of a cylindrical wall segment, and wherein different angular extents of the two different materials about the cylindrical wall results in different resultant forms of the shaping part after annealing.
