Abstract

A medical device system and method for monitoring a patient include a monitoring device for storing data relating to the patient and a digital pen for digitizing and storing data handwritten by the patient. A control module is configured to aggregate data stored by the monitoring device and handwritten data stored by the digital pen.

Claims

1. A medical device system, comprising:

a monitoring device for storing data relating to a patient;

a digital pen for digitizing and storing handwritten data; and

a control module configured to aggregate data stored by the monitoring device and handwritten data stored by the digital pen.

2. The medical device system of claim 1 wherein the digital pen comprises an image capture module for capturing an image of handwritten data.

3. The medical device system of claim 1 wherein the digital pen comprises a data conversion module for converting digitized data to a character encoded format.

4. The medical device system of claim 1 wherein the digital pen comprises a communication module configured for bidirectional communication with the control module for transferring the stored handwritten data to the control module.

5. The system of claim 1 wherein the monitoring device comprises a sensor for sensing a physiological signal and the data stored by the monitoring device includes physiological signal data.

6. The system of claim 1 wherein the monitoring device comprises a therapy delivery module and the data stored by the monitoring device includes therapy delivery data.

7. The system of claim 1 wherein the monitoring device being configured to perform device diagnostic tests and the data stored by the monitoring device includes device-related diagnostic data.

8. The system of claim 1 wherein the monitoring device being an implantable medical device.

9. The system of claim 1 wherein the control module being included in the monitoring device.

10. The system of claim 8 further comprising an external device, the external device including an external communication module;

wherein the control module being included in the external device;

wherein the implantable medical device comprises an implantable communications module in communication with the external communication module for transmitting the stored data to the control module and the digital pen comprises a communication module in communication with the external device for transferring the stored handwritten data to the control module.

11. The system of claim 1 further comprising a networked central database and wherein the control module being in communication with the networked central database and configured to transfer aggregated data to the networked central database.

12. The system of claim 4 wherein the monitoring device comprises a communications module configured for bidirectional communication with the digital pen and wherein the monitoring device being configured to store data in response to receiving a signal from the digital pen.

13. The system of claim 4 wherein the monitoring device comprises a communications module configured for bidirectional communication with the digital pen and further comprises a therapy delivery module responsive to handwritten data received from the digital pen.

14. The system of claim 1 wherein aggregation of the data includes chronologically aligning handwritten data stored by the digital pen and data stored by the monitoring device.

15. The system of claim 2 further comprising a paper for use with the digital pen, the paper being formatted in at least one area for recognition of medical data using at least one unique identifier preprinted on the paper.

16. The system of claim 15 wherein the at least one unique identifier corresponds to a patient symptom.

17. The system of claim 15 wherein the control module being programmable and the at least one unique identifier being programmably assigned to a medical parameter.

18. The system of claim 17 wherein programmably assigning the unique identifier includes capturing handwritten data corresponding to the medical parameter.

19. A method for monitoring a patient, comprising:

digitizing handwritten data;

storing data acquired by a monitoring device, and

aggregating the handwritten data with the stored data.
