METHOD FOR CLOCK MANAGEMENT FOR AN IMPLANTABLE MEDICAL DEVICE
First Claim
1. A method for adjusting the clock time of an implantable device, comprising:
- establishing communication between an external device and the implantable device;
comparing a clock time of the external device to a clock time of the implantable device and determining whether a discrepancy exists;
determining whether the discrepancy is less than a pre-determined threshold; and
updating the clock time of the implantable device if the discrepancy is less than the pre-determined threshold.

Abstract
An implantable medical device is capable of delivering the therapeutic output to the patient. A controller, programmable by a medical professional, is operatively coupled to the implantable medical device to, in part, program the therapeutic output to be delivered to the patient. The controller has an interface allowing the medical professional to select an amount of the therapeutic output to be delivered to the patient in at least one of the series of discrete timer intervals. However, the therapeutic output deliver to the patient is dependant upon the clock time to which the infusion device. In certain situations the infusion device clock time may have inaccuracies that grow over time. The clock time can be reset by the infusion programmer but a method must be in place to determine and account for resetting the infusion device clock time that controls when the therapy will be delivered.

14. A method for updating the clock time of an implantable device, comprising:
-
establishing connection between an external device and the implantable device; comparing a clock time of the external device to the clock time of the implantable device and determining whether a difference exists; informing a user if a difference exists; determining the impact on a delivery of therapy if the clock time of the implantable device is adjusted to the clock time of the external device; informing the user of the impact; requesting input from the user based upon the impact; and updating the clock time of the implantable device based upon the user'"'"'s input. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A system for delivery therapy comprising:
-
an implantable device including device electronics disposed in a housing and means for delivering therapy to a patient; a programmer including programmer electronics disposed in a housing; a communication system including a first portion disposed in the implantable device and a second portion disposed in the programmer, the communication system allowing communication between the implantable device and the programmer, the first portion and the second portion operably connected to the device electronics and the programmer electronics, respectively; and first and second clock electronics disposed in the implantable device and the programmer and operably coupled to the device electronics and the programmer electronics, respectively, the clock electronics each including a computer readable medium containing instructions that when implemented cause the device electronics to check a device clock against the programmer clock and to either automatically adjust the device clock to match the programmer clock or present a clock error signal to a user.

22. A method for adjusting the clock time of an implantable device, comprising:
-
establishing communication between an external device and the implantable device; comparing a clock time of the external device to a clock time of the implantable device and determining whether a discrepancy exists; determining whether the discrepancy is less than a pre-determined threshold; updating the clock time of the implantable device if the discrepancy is less than the pre-determined threshold; and calculating and implementing a new simple continuous rate. - View Dependent Claims (23, 24)
