Abstract

A distributed multi-user system for real time data access during cardiology procedures. The system includes an interactive computer network which can be used to simultaneously display and manipulate data from a cardiology procedure on a plurality of devices and at a plurality of locations. The system is implemented through various replication topologies which allow the simultaneous access and annotation of a cardiology study during the procedure. The study can be displayed and annotated at any of the plurality of locations, which may be local or remote, during the procedure. Annotations made at one of the plurality of locations will be distributed to the other locations through a publisher.

Claims

1. A method of annotating a study record taken during a cardiac catheterization procedure, the procedure being conducted in a cardiac catheterization lab, comprising the acts of:

(a) inserting at least one catheter into a patient comprising a heart, the catheters terminating in a position proximate to the heart and comprising one or more sensors configured to sense data from the heart;

(b) stimulating the heart with electrical signals from the catheter;

(c) sensing data from the heart;

(d) transmitting the data from the sensors to a data collection device;

(e) transmitting the data from the data collection device to a central publisher;

(f) replicating the data;

(g) transmitting the replicated data from the central publisher to a plurality of client workstations;

(h) annotating the replicated data at at least one of the plurality of client workstations to produce annotated data;

(i) transmitting the annotated data from the at least one client workstation to the central publisher;

(j) replicating the annotated data; and

(k) transmitting the replicated annotated data from the central publisher to the plurality of client workstations.

2. The method, as set forth in claim 1, wherein the catheterization procedure comprises an electrophysiology procedure.

3. The method, as set forth in claim 1, wherein the catheterization procedure comprises an ablation procedure.

4. The method, as set forth in claim 1, wherein the central publisher is located within the cardiac catheterization lab.

5. The method, as set forth in claim 1, wherein each of the plurality of client workstations comprises a monitor configured to display digital data.

6. The method, as set forth in claim 1, wherein act (c) comprises the act of sensing electrical data from the heart.

7. The method, as set forth in claim 1, wherein act (c) comprises the act of sensing hemodynamic data from the heart.

8. The method, as set forth in claim 1, wherein the central publisher comprises a server.

9. The method, as set forth in claim 4, wherein the server is located locally with respect to the cardiac catheterization lab.

10. The method, as set forth in claim 1, further comprising simultaneously displaying the data on the plurality of client workstations.

11. The method, as set forth in claim 10, wherein the act of simultaneously displaying the data on the plurality of client workstations occurs in real time.

12. The method, as set forth in claim 10, wherein the act comprises simultaneously displaying the data on the plurality of client workstations during the cardiac catheterization procedure.

13. The method, as set forth in claim 12, wherein at least one of the plurality of client workstations is located remotely with respect to the cardiac catheterization lab.

14. A method of annotating a study record taken during a cardiac catheterization procedure, the procedure being conducted in a cardiac catheterization lab, comprising the acts of:

(a) transmitting data from a catheter to a data collection device;

(b) transmitting the data from the data collection device to a central publisher;

(c) replicating the data;

(d) transmitting the replicated data from the central publisher to a plurality of client workstations; and

(e) annotating the replicated data at at least one of the plurality of client workstations to produce annotated data;

(f) transmitting the annotated data from the at least one client workstation to the central publisher;

(g) replicating the annotated data; and

(h) transmitting the replicated annotated data from the central publisher to the plurality of client workstations.

15. The method, as set forth in claim 14, wherein the catheterization procedure comprises a electrophysiology procedure.

16. The method, as set forth in claim 14, wherein the catheterization procedure comprises an ablation procedure.

17. The method, as set forth in claim 14, wherein the central publisher is located within the cardiac catheterization lab.

18. The method, as set forth in claim 14, wherein each of the plurality of client workstations comprises a monitor configured to display digital data.

19. The method, as set forth in claim 14, wherein act (a) comprises the act of transmitting electrical data from the heart.

20. The method, as set forth in claim 14, wherein act (a) comprises the act of transmitting hemodynamic data from the heart.

21. The method, as set forth in claim 14, wherein the central publisher comprises a server.

22. The method, as set forth in claim 21, wherein the server is located locally with respect to the cardiac catheterization lab.

23. The method, as set forth in claim 14, further comprising simultaneously displaying the data on the plurality of client workstations.

24. The method, as set forth in claim 23, wherein the act of simultaneously displaying the data on the plurality of client workstations occurs in real time.

25. The method, as set forth in claim 23, wherein the act comprises simultaneously displaying the data on the plurality of client workstations during the cardiac catheterization procedure.

26. The method, as set forth in claim 25, wherein at least one of the plurality of client workstations is located remotely with respect to the cardiac catheterization lab.

27. A system comprising:
