Abstract

A medical device can include a therapy circuit configured to provide a specified electrostimulation therapy to a tissue site, the specified electrostimulation therapy including a scheduled completion, the therapy circuit including a protection circuit configured to adjust specification of the electrostimulation therapy being provided so as to provide an adjusted electrostimulation therapy before the scheduled completion. The medical device can include a monitoring circuit comprising a comparator. The monitoring circuit can be configured to trigger the protection circuit to inhibit the therapy circuit when the therapy circuit output parameter exceeds the specified threshold as indicated by the comparator.
