Method and apparatus for resetting programming parameters within an implantable medical device
First Claim
1. An implantable medical device comprising:
- a parameter storage unit that is operative to store parameter data corresponding to at least two programming states;
a receiver that is operative to receive communication signals from an external device; and
a controller that is connected to the parameter storage unit and to the receiver and that controls the operation of the implantable medical device according to a selected one of the programming states, wherein the controller is responsive to receipt of a reset signal by the receiver to retrieve parameter data from the parameter storage unit corresponding to another of the programming states and to implement the parameter data to change the programming state;
wherein the programming states in the parameter storage unit are ordered such that one of the stored programming states is selected according to its order in the parameter storage unit as a current programming state.

Abstract
An external programmer is provided with the capability of automatically resetting the programming state of an implantable medical device to a previous programming state. To this end, the pacemaker maintains parameters representative of current and past programming states. In response to a physician-initiated reset function using an external programmer, the pacemaker transfers information pertaining to the programming states to the external programmer along with a pointer identifying the current state. The physician selects one of the previous programming states and the external programmer then updates the pointer to identify the selected state and transmits the pointer back to the pacemaker. The pacemaker accesses the programming parameters stored therein corresponding to the programming state identified by the new pointer and is reprogrammed. Accordingly, the programming state of the pacemaker is reset to the previous programming state without requiring manual reentry of the parameters. The external programmer may also be configured to enable the physician to modify parameters or to display differences between two or more programming states of the medical device. Also, the external programmer may be configured to enable the physician to merge parameters from two or more programming states to create a new programming state.
