1. A device, comprising: a sheath comprising: an annulus to receive an implanted lead,a separator to substantially free the implanted lead from surrounding tissue, andan electrically conductive structure to interact electrically with a conductor of the lead, the electrically conductive structure comprising at least one conductive band around at least art of a circumference of the sheath, and the at least one conductive band comprising plural conductive bands positioned along a length of the sheath;a sensor to sense an electrical parameter associated with the lead to determine a condition of an insulation layer of the lead; anda controller operable to receive output from the sensor and determine when the condition of the insulation layer is not acceptable. 2. The device of claim 1, further comprising: a marker in spatial proximity to the electrically conductive structure to indicate a location of an unacceptable portion of the insulation layer. 3. The device of claim 1, wherein the electrically conductive structure is connected to a voltage source and the sensor. 4. The device of claim 1, wherein the conductor of the lead is connected to the sensor and wherein the electrically conductive structure is connected to a voltage source. 5. A device, comprising: a sheath comprising: an annulus to receive an implanted lead,a separator to substantially free the implanted lead from surrounding tissue, andan electrically conductive structure to interact electrically with a conductor of the lead;a sensor to sense an electrical parameter associated with the lead to determine a condition of an insulation layer of the lead; anda controller operable to receive output from the sensor and determine when the condition of the insulation layer is not acceptable;wherein the electrically conductive structure is connected to the sensor.
