Abstract
A stimulation engine configured to identify a fault condition in an implantable lead, including a regulator configured to deliver an electrical pulse between at least two electrodes of the implantable stimulation lead, and a sensing module configured to detect at least an initial voltage and a subsequent voltage between the at least two electrodes at different times during delivery of the electrical pulse, and compare at least the subsequent voltage to a defined threshold value representing an expected voltage at the same time during the electrical pulse to determine the presence of a fault condition.
Claims13
A medical device, comprising:
- a stimulation engine having a regulator configured to deliver electrical signals;
- and
- an implantable stimulation lead including at least two electrodes in electrical communication with the stimulation engine,
- wherein the stimulation engine is configured to—
- deliver an electrical pulse to the at least two electrodes using the regulator,
- detect two or more delivery voltages between the at least two electrodes at different times during delivery of the electrical pulse,
- compare at least one of the two or more delivery voltages to a defined threshold value, wherein the defined threshold value represents an expected delivery voltage at a corresponding time for the at least one of the two or more delivery voltages detected during the electrical pulse,
- determine whether a fault condition is present based on the comparison of the at least one of the two or more delivery voltages and the defined threshold value, and
- communicate the fault condition determination to an external programmer in wireless communication with the medical device.
