1. A load-carrying body for reducing torsional and tensile loading on electronic components in an An implantable medical electrical lead, comprising:
- a) a lead conductor extending from a proximal lead conductor end to a distal lead conductor end, wherein the proximal lead conductor end is connectable to an implantable pulse generator;
b) an electrode configured for contact with body tissue;
c) an electronic component disposed in-line with an implantable medical electrical lead, the electronic component having a proximal electronic component end conductively and physically coupled to a the distal lead conductor end, and a distal electronic component end conductively and physically coupled to a lead the electrode; and
d) a casing forrigid, torque bearing member supporting the electronic component, wherein a proximal end of the casing being torque bearing member is mechanically, but not conductively coupled to the distal lead conductor end, and a distal end of the torque bearing member is mechanically, but not conductively coupled to the electrode, and so as to isolatee) wherein the torque bearing member isolates the electronic component from torque or tensile loads applied to the lead conductor, the lead electrode, or both.

Abstract
A load-carrying body for reducing torsional and tensile loading on electrical components in an implantable medical electrical lead includes an electronic component disposed in-line with the implantable medical electrical lead, and a casing for the electronic component. The electronic component has a proximal end conductively coupled to a lead conductor and a distal end conductively coupled to a lead electrode. The casing is mechanically coupled to the lead so as to isolate the electrical component from torque or tensile loads applied to the lead, the lead electrode, or both.
