Abstract

An alert system for alerting a clinician to an occurrence of an event detected by an implantable medical device includes a monitor and a patient management network. The implantable medical device includes a means for detecting the occurrence of the event and initiating a wireless transmission of data related to the event. The monitor is configured to receive the wireless transmission of data and transfer the data. The patient management network is configured to receive the data and store the data on a data storage device. The patient management network includes a web presentation service for creating a website from the data stored on the data storage device, the website configured to alert the clinician to the occurrence of the event.

Claims

1. A method of alerting a clinician to the occurrence of an event within a patient, the method comprising:

detecting the occurrence of the event with an implantable medical device, the implantable medical device being implanted within the patient;

wirelessly transmitting an alert signal from the implantable medical device to alert the clinician to the occurrence of the event;

determining whether the alert signal was successfully communicated; and

alerting a patient to the occurrence of the event if it is determined that the alert signal was not successfully communicated.

2. The method of claim 1, wherein determining whether the alert signal was successfully communicated comprises determining whether the alert signal was received by a monitor.

3. The method of claim 1, wherein determining whether the alert signal was successfully communicated comprises determining whether an interrogation of the implantable medical device by a monitor was completed.

4. The method of claim 1, wherein determining whether the alert signal was successfully communicated comprises determining whether a patient management network received the alert signal.

5. The method of claim 1, wherein determining whether the alert signal was successfully communicated comprises determining whether the clinician has acknowledged receipt of the alert from a patient management network.

6. The method of claim 1, wherein determining whether the alert signal was successfully communicated comprises determining whether the clinician has received data related to the patient after being alerted by a patient management network.

7. The method of claim 1, wherein attempting to wirelessly transmit an alert signal comprises wirelessly transmitting an alert signal to a monitor, the method further comprising:

receiving the alert signal with the monitor such that the attempt to wirelessly transmit the alert signal is successful;

performing a wireless interrogation of the implantable medical device to wirelessly transfer data from the implantable medical device to the monitor;

transferring the data from the monitor to a patient management network;

storing the data on the patient management network; and

creating a web page from the stored data to alert the clinician to the occurrence of the event.

8. The method of claim 7, further comprising creating a second web page from the stored data to provide supplemental information to the patient related to the event.

9. The method of claim 7, wherein transferring the data from the monitor to the patient management network comprises:

transferring the data over a telephone line to a private network; and

transferring the data over the private network to the patient management network.

10. The method of claim 1, wherein detecting the occurrence of the event comprises detecting the occurrence of an event relating to a therapy delivery.

11. The method of claim 1, wherein detecting the occurrence of the event comprises detecting the occurrence of an event relating to an arrhythmia.

12. The method of claim 1, wherein detecting the occurrence of the event comprises detecting the occurrence of an event relating to heart failure.

13. The method of claim 1, wherein detecting the occurrence of the event comprises detecting the occurrence of an event relating to system integrity.

14. The method of claim 1, wherein detecting the occurrence of the event comprises detecting the occurrence of an event relating to ischemia.
