First Claim
Patent Images
1. A medical electrical lead-electrode system, comprising:
- a first conductor having a first switching means connected at a first distal end, the first switching means being selectively coupled to a first electrode;
a second conductor having a second switching means connected at a second distal end; and
a capacitor disposed proximate to the first and second distal ends, wherein the first switching means is actuated to decouple the first electrode and couple a first terminal of the capacitor and the second switching means couples a second terminal of the capacitor.

Abstract
This disclosure relates to a medical electrical lead having fault detection and fault isolation. The lead may include a first conductor coupled to a first electrode and a second conductor coupled to a second electrode. A capacitor is disposed within the lead and selectively coupled to the first and second conductors of the lead. The capacitor is charged in a test mode of operation after the first and second electrodes have been isolated from the conductors via an isolation mechanism and the capacitor will discharge through the first and second conductors. The capacitor discharge morphology is processed to detect lead-related conditions.
