First Claim
Patent Images
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; and
a controller operable to receive output from the sensor and determine when the condition of the insulation layer is not acceptable.
