System for evaluating performance of an implantable medical device
First Claim
1. A system for use with an implantable medical device, the system comprising:
- a remote external server, comprising;
a physiological data input, configured to receive physiological data into a patient data storage device that stores historical physiological data of a population of congestive heart failure (CHF) patients, the physiological data input comprising an implantable physiological data input configured to receive implantable physiological data from an implantable physiological sensor of a first patient;
a processor, coupled to the patient data storage device, the processor configured to apply multiple algorithm variations against the same implantable physiological data from the first patient to produce corresponding resulting CHF indicators; and
a local or remote external user interface, configured to be coupled to the remote external server using a communications network, the local or remote external user interface comprising a display, configured to display to a user information allowing comparison between the resulting CHF indicators from the multiple algorithm variations, and the display including a population data selector configured to permit the user to select physiological data from a population comprising a different set of one or more patients or physiological data collected over a period of time from the first patient,wherein the processor is configured to automatically reprogram the implantable medical device with an algorithm selected from the multiple algorithm variations as a function of a false positive rate and a sensitivity.

Abstract
A system evaluates the performance of an implantable medical device, such as by using a remote external server and a user interface and stored historical physiological data of a population of congestive heart failure (CHF) patients. A processor is coupled to a patient data storage device to apply multiple algorithm variations against the same implantable physiological data from the patient to produce corresponding resulting CHF indicators. The user interface includes a display that is configured to display to a user information allowing comparison between the resulting CHF indicators from the multiple algorithm variations. The display also includes a population data selector to permit the user to select physiological data from a population that includes a different set of one or more patients or physiological data collected over a period of time from the patient. This permits optimization of an algorithm parameter or selection of a best performing algorithm.
