Patent Images
1. An implantable medical device, comprising:
- a hermetically-sealed implantable housing;
an exposed first conductor located on or near the housing;
at least one insulated second conductor located near the exposed first conductor; and
an isolation test circuit configured to provide a test stimulus to the exposed first conductor and configured to measure a portion of the test stimulus coupled to the second conductor, the isolation test circuit including;
a comparator configured to compare the portion of the test stimulus coupled to the second conductor to a specified threshold value; and
a controller circuit configured to trigger an alert to a user in response to the comparison when the portion of the stimulus coupled to the second conductor exceeds the specified threshold value.

Abstract
An implantable medical device can include a hermetically-sealed implantable housing, an exposed first conductor located on or near the housing, and at least one insulated second conductor located near the exposed first conductor. In an example, the implantable medical device can include an isolation test circuit to provide a test stimulus to the exposed first conductor and configured to measure a portion of the test stimulus coupled to the second conductor.

11. An implantable medical device, comprising:
-
a hermetically-sealed implantable housing; an exposed first conductor located on or near the housing; at least one insulated second conductor located near the exposed first conductor; and an isolation test circuit configured to provide a test stimulus to the exposed first conductor and configured to measure a portion of the test stimulus coupled to the second conductor, the isolation test circuit including; a comparator configured to compare the portion of the test stimulus coupled to the second conductor to a specified threshold value; a controller circuit configured to trigger an alert to a user in response to the comparison when the portion of the stimulus coupled to the second conductor exceeds the specified threshold value; a magnetic detector coupled to the controller circuit and wherein the controller circuit is configured to provide a trigger to the isolation test circuit, the trigger causing the isolation test circuit to measure the coupled portion between the first and second conductors when the magnetic detector is exposed to a magnetic field having an intensity above a specified threshold.

12. A method, comprising:
-
providing an isolation test between a first conductor located on or near a hermetically-sealed implantable medical device housing and at least one insulated second conductor located near the exposed first conductor, the isolation test including; providing a test stimulus to the exposed first conductor using an isolation test circuit included in the implantable medical device housing; measuring a portion of the test stimulus coupled to the insulated second conductor; and comparing the measured portion of the test stimulus to a specified threshold value; and in response triggering an alert to a user using a control circuit included within the implantable medical device housing when the comparing the measured portion indicates that the measured portion exceeds the specified threshold value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
