Abstract

A method and structure for notifying clinicians with patients with implantable medical devices (IMDs), about recalls and upgrades, therapy improvements, longevity estimates/improvements, and follow-up frequency recommendations is implemented in an interactive preferably wireless communications system involving a preferably web-enabled remote expert station. Either the clinician or the patient may initiate and access the remote expert station. During such communications, the patient'"'"'s IMDs are evaluated against a first database comprising patient data and a second database comprising statistical, survivability, probability projections. The patient or the clinician may also access a database containing patient-specific information including other device information. If one or more of the patient'"'"'s IMDs matches with a recalled or an up-gradable unit such message is posted to the clinician and the patient. Remedial action is taken, by replacing the unit, upgrading/reprogramming the unit, adjusting the patient'"'"'s follow-up timing to thereby ensure effective and safe therapy and clinical care.

Claims

1. An integrated bi-directional data communication and follow-up system for at least one implanted medical device (IMD), the system comprising:

the at least one IMD having a memory that stores device information, operational parameters, physiological and medical data, performance logs and therapy events;

an external interface device being in wireless data communication with the at least one IMD including a data management system to enable data transfer and exchange between the at least one IMD and one of and combinations of said external interface device and a remote expert station;

a network enabling the bi-directional communication system between the at least one IMD, said external interface device and said remote expert station;

means for reviewing said performance logs;

means for updating the at least one IMD over said network; and

said means for reviewing and said means for updating being implemented in one of and combination of said external interface device and said remote expert station to update the at least one IMD based on performance logs retrieved from said memory.

2. The system of claim 1 wherein said device data includes data relating to initial implant.

3. The system of claim 1 wherein said performance logs is reviewed by said means for reviewing on a chronic basis.

4. The system of claim 3 wherein said performance logs is reviewed by said means for reviewing on a periodic basis.

5. The system of claim 1 wherein said data management includes a statistical survival probability projection data based on the population of implanted medical devices related to the at least one IMD.

6. The system of claim 5 wherein said projection data is implemented to generate implanted medical device safety and performance data set to compare said performance logs against said performance data set.

7. The system of claim 6 wherein said data set is implemented to identify of whether the at least one IMD is out of specification.

8. The system of claim 1 wherein said means for updating includes upgrading/reprogramming the at least one IMD.
