Abstract
A system, method and leak signal discriminator for detection of a leak or mechanical breach in a catheter shaft in the presence of an electrical interferer are disclosed. According to one aspect, a leak signal discriminator having a leak detection circuit is configured to distinguish between a leak signal arising from a leak in a catheter and an interfering signal arising from an electrical interferer. The leak signal discriminator includes circuitry configured to receive from the leak detection circuit a response signal responsive to a test signal the test signal having component signals, each component signal being at a different frequency, and distinguish between a leak and an electrical interferer based at least in part on an evaluation of the response signal.
