TRANSVASCULAR LEAD WITH PROXIMAL FORCE RELIEF
First Claim
1. A medical electrical lead for implantation in a patient'"'"'s internal jugular vein at a target location adjacent to a vagus nerve, the lead comprising:
- a proximal region having a proximal stiffness;
a distal region having a distal stiffness and a first spiral configured to retain the distal region in the internal jugular vein;
a transition region interposed between the proximal and distal regions and having a transitional stiffness; and
an electrode coupled to the distal region;
wherein the proximal stiffness is less than the distal stiffness so as to reduce an amount of force transferred from the proximal region to the distal region and the transitional stiffness is less than the distal stiffness and greater than the proximal stiffness.

Abstract
A medical electrical lead for implantation in a patient'"'"'s internal jugular vein at a target location and adjacent a vagus nerve. The lead comprises a proximal region having a proximal stiffness and a distal region. The distal region has a distal stiffness and a first spiral configured to retain the distal region in the internal jugular vein. A transition region is interposed between the proximal and distal regions and has a transitional stiffness. An electrode is coupled to the distal region. The proximal stiffness is less than the distal stiffness so as to reduce an amount of force transferred from the proximal region to the distal region. The transitional stiffness is less than the distal stiffness and greater than the proximal stiffness.
