US 9,956,417 B2 · Identifying lead insulation breaches and externalization of lead conductors

Abstract

A technique for identifying lead-related conditions, such as insulation breaches and/or externalization of lead conductors, includes analyzing characteristics of electrical signals generated on one or more electrode sensing vectors of the lead by a test signal to determine whether a lead-related condition exists. The characteristics of the electrical signals induced on the lead by the test signal may be significantly different on a lead having an insulation breach or externalized conductor than on a lead not having such lead-related conditions. As such, the implantable medical device may be subject to a known test signal and analyze the signals on the lead to detect lead-related conditions.

Dependent claims

An implantable medical system comprising:

at least one implantable medical lead;
and
an implantable medical device coupled to the at least one implantable medical lead, wherein the at least one implantable medical lead includes a plurality of electrodes, wherein the implantable medical device includes:
a signal generator configured to generate a test signal and deliver the test signal via a first electrode vector that includes at least one of the plurality of electrodes;
and
a processor configured to obtain an electrical signal generated on the lead by delivery of the test signal and analyze the electrical signal to determine whether a lead-related condition exists, wherein the electrical signal is sensed on a second electrode vector that has at least one electrode of the plurality of electrodes different than the first electrode vector.
