Abstract
The operation of an implantable medical device executing at least one set of firmware code is modified using a hardware/firmware trap at a point of execution of the set of firmware code. A patch code for directing the implantable medical device to perform a particular task is provided for execution when the trap generates an interrupt. The operation thereafter returns to the point of execution of the set of firmware code where the interrupt was generated and execution of the set of firmware code continues in a normal manner.
