Abstract
An elongate body of a medical electrical lead includes at least one conductor formed into a coil that includes a first portion and a second portion, wherein the first portion extends within an outer insulation sheath and the second portion extends outside the outer insulation sheath to be exposed to an environment external to the lead body as an energy dissipating shunt.
Claims27
A medical electrical lead, comprising:
- a stimulation electrode;
- and
- an elongate body including an outer insulation sheath and at least one conductor coupled to the stimulation electrode and formed into a coil;
- the coil including a first portion, extending within the outer insulation sheath, and a second portion, disposed proximal to the stimulation electrode and extending outside the outer insulation sheath such that the second portion of the coil is exposed to an environment external to the lead body as an energy dissipating shunt;
- and
- the at least one conductor including a wire and an insulative jacket extending about an entire circumference of the wire along at least a length of the at least one conductor that forms the second portion of the coil.

A medical electrical lead, comprising:
- a first electrode and a second electrode disposed proximal to the first electrode;
- and
- an elongate body including an outer insulation sheath and first and second conductors coupled to the first and second electrodes, respectively, and being formed into a coil;
- the coil including a first portion, extending within the outer insulation sheath and including a distal end, and a second portion, disposed between the first and second electrodes and extending outside the outer insulation sheath such that the second portion of the coil is exposed to an environment external to the lead body as an energy dissipating shunt;
- the second conductor terminated in proximity to the distal end of the first portion of the coil;
- and
- the first conductor including a wire and an insulative jacket extending about an entire circumference of the wire along at least a length of the first conductor that forms the second portion of the coil.
