Alarm for lead insulation abnormality
View Patent ↗A system is provided to determine whether an insulating layer of an implanted lead is damaged.
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, and
an 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.
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, and
an 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; and
a 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.
