Patent ID: 8718772

Claim:
A system comprising: an implantable medical device, configured to be implanted within a body of a patient, the implantable medical device comprising: electrical circuitry, configured to deliver electrical therapy to the patient; a first digital storage area for holding normal operation instructions and settings; a second digital storage area for holding temporary operating instructions and settings; a communication subsystem; and a timing subsystem, and wherein upon receiving from an external interface device an instruction to use the temporary operating instructions and settings to deliver the electrical therapy to the patient, the implantable medical device initiates a first predetermined period of time during which the implantable medical device begins delivering the electrical therapy using the temporary operation instructions and settings, and wherein the implantable medical device will revert to the normal operation instructions and settings when a first poll-response time limit is reached during the first predetermined period of time; and wherein upon completion of the first predetermined period of time without reverting to normal operation, the implantable medical device initiates a second predetermined period of time during which the implantable medical device is configured to revert to the normal operation instructions and settings when a second poll-response time limit is reached during the second predetermined period of time, wherein the second poll-response time limit is longer than the first poll-response time limit.
