First Claim
Patent Images
1. An implantable medical device, the implantable medical device comprising:
- a) a battery, the battery providing power to the implantable medical device;
b) a replacement indicator timer, the replacement indicator timer counting a replacement time period to a determined replacement date for the implantable medical device, the replacement indicator timer starting the counting when an operational characteristic of the battery reaches a selected value; and
c) means for automatically determining, once the replacement indicator timer begins counting, whether one of an interrogation of a device parameter and a reprogramming of an operational parameter have occurred.

Abstract
A system and method is provided for reliably indicating that an implantable medical device is in need of replacement. The system and method measures the operational characteristics of the battery and the operational parameters of the implantable device itself. When these characteristics and parameters reach a defined level, the implantable medical device starts a replacement indicator timer. The replacement indicator timer starts and counts a replacement time period, with the replacement time period ending at a determined replacement date. The determined replacement date is the date at which the implantable medical device should be replaced.

19. A method for providing notice to a clinician of a removal date for an implantable medical device, the method comprising the steps of:
-
a) monitoring an operational characteristic of a battery in the implantable medical device during operation of the implantable medical device; b) starting a replacement indicator timer in the implantable medical device when the operational characteristic of the battery reaches a selected value; c) automatically determining if one of an interrogation of a device parameter and a reprogramming of an operational parameter have occurred; d) counting through a replacement time period with the replacement indicator timer to a determined replacement date; and e) communicating a status of the replacement indicator timer to the clinician. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
