1. A system, comprising:
- a sheath comprising;
an annulus to receive an implanted lead; and
an electrically conductive structure forming a distal tip of the sheath, the electrically conductive structure operable to provide, in the event of an irregularity in an insulating layer of an implanted lead, a changed electrical parameter associated with the lead;
a sensor connected to the electrically conductive structure and operable to sense the changed electrical parameter; and
a controller operable to determine an instance of an irregularity in the lead based on the sensed, changed electrical parameter and warn a physician of the determined instance of an irregularity.
