Force-decoupled and strain relieving lead and methods of making and using
First Claim
1. An electrical stimulation lead, comprising:
- a lead body having a distal end portion, a proximal end portion, and a longitudinal length;
a plurality of terminals disposed along the proximal end portion of the lead body;
a plurality of electrodes disposed along the distal end portion of the lead body; and
a plurality of conductors extending along the lead body and electrically coupling the terminals to the electrodes;
wherein the lead body comprises an intermediate portion disposed between the proximal end portion and the distal end portion, wherein the intermediate portion comprises at least one separation element that extends longitudinally along the intermediate portion, wherein the intermediate portion is deployable from an undeployed configuration to a deployed configuration responsive to operation of the at least one separation element, wherein, in the undeployed configuration, the intermediate portion defines a central lumen with the conductors arranged concentrically about the central lumen of the intermediate portion, wherein, in the deployed configuration, the intermediate portion defines at least one row of the conductors, wherein each of the at least one row comprises at least two of the conductors, wherein each of the at least one row is linear or arc-shaped when the intermediate portion is in the deployed configuration.

Abstract
An electrical stimulation lead includes a lead body having a distal end portion, a proximal end portion, and a longitudinal length; terminals disposed along the proximal end portion of the lead body; electrodes disposed along the distal end portion of the lead body; and conductors extending along the lead body and electrically coupling the terminals to the electrodes. The lead body includes an intermediate portion disposed between the proximal end portion and the distal end portion. The intermediate portion includes at least one separation element that extends longitudinally along the intermediate portion and the intermediate portion is deployable from an undeployed configuration to a deployed configuration responsive to operation of the at least one separation element.
