Abstract

A system is described for allowing medical data obtained at a local site to be transferred to a data processing system located at a remote site. This medical data may include video data and/or data obtained from one or more medical devices such as a fluoroscopy device or an electrocardiograph (ECG) signal monitoring device. The data may be viewed on one or more display windows of the remote data processing system to allow a remotely-located expert to participate in an examination or medical procedure being conducted at the local site. In one embodiment, the remote data processing system also receives screen data from an implantable medical device programmer that is located at the local site. This screen data may include data associated with the configuration of the programmer, the configuration of an implantable medical device, and other information obtained from a patient such as physiological waveforms. Routing of all data may be performed by a communication hub operating as a stand alone device. Alternatively, the data routing function may be implemented on the programmer.

9. The system of claim 1, wherein the display means includes means for displaying the display screen data.

10. The system of claim 9, wherein the display means includes means for displaying the display screen data in substantially real-time.

11. The system of claim 9, wherein the display means includes means for allowing a user to activate multiple displays simultaneously, each of the displays for displaying one or more of the screen data, the medical data, and the video-formatted data.

12. The system of claim 9, wherein the programmer includes a cursor that may be controlled at the patient site, wherein the programmer includes means for transferring first cursor information indicative of cursor control at the patient site to the communications network, and wherein the display means includes means for using the first cursor information to monitor the control of the cursor at the patient site.

13. The system of claim 12, wherein the receiving device includes mean for allowing the cursor to be controlled at the remote site, wherein the receive device includes means for transferring second cursor information indicative of cursor control at the remote site to the communications network, and wherein the programmer includes means for using the second cursor information means to monitor the control of the cursor at the remote site.

14. The system of claim 9, wherein the programmer is coupled to the at least one medical device and to the video device, and the hub is implemented on the programmer to route data between each of the video device and the at least one medical device and the communications network.

15. The system of claim 9, and further comprising a device to receive an audio signal, the device being coupled to transfer the audio signal to the communications network, and wherein the receiving device includes an audio system to allow the audio signal to be monitored at the remote site.
