Abstract

Disclosed herein is an implantable medical lead configured to receive a stylet. The lead may include a tubular body and a structure. The tubular body may include a distal end and a proximal end. The body may be configured to receive the stylet. The structure longitudinally may extend through the body between the distal end and the proximal end. The structure may be anchored within the body such that a tensile force arising within the body by the stylet being extended through the body causes the tensile force to be substantially carried by the structure.

Claims

1. An implantable medical lead configured to receive a stylet, the lead comprising:

a tubular body including a distal end and a proximal end, wherein the body is configured to receive the stylet;

an electrode on the tubular body;

a stylet stop disposed near the distal end;

an electrical conductor longitudinally extending through a wall of the body between the distal end and the proximal end;

wherein the electrical conductor is directly and mechanically connected to the stylet stop and in electrical communication with the electrode; and

a heat shrink layer around a portion of the tubular body extending around the stylet stop.

2. The lead of claim 1, wherein the electrical conductor includes a lumen.

3. The lead of claim 2, wherein the lumen includes a polymer.

4. The lead of claim 3, wherein the body further includes an insulation layer forming the wall and the polymer is different from a material forming the insulation layer.

5. The lead of claim 1, wherein the electrical conductor includes at least one of a conductive core and an insulation jacket.

6. The lead of claim 1, further comprising a grooved member near the proximal end.

7. The lead of claim 6, wherein the electrical conductor is routed along a groove of the grooved member.
