Patent ID: 8406895

Claim:
An implantable medical device lead comprising: an insulative lead body; an outer conductive coil extending through the lead body, the outer conductive coil coupled to a proximal electrode at a distal end of the outer conductive coil; an inner conductive coil extending coaxially with the outer conductive coil and coupled to a distal electrode at a distal end of the inner conductive coil; and a cooling assembly thermally coupled to the distal electrode to dissipate heat generated at the distal electrode during exposure to magnetic resonance imaging (MRI) fields, wherein the cooling assembly comprises one or more thermoelectric elements encased in a thermally conductive biocompatible material, and wherein the one or more thermoelectric elements are configured to electrically couple to an energy storage device that stores energy generated by the one or more thermoelectric elements when dissipating heat from the distal electrode.
