Abstract

A computerized system collects, organizes and stores various sets of data during several phases of treatment relating to monitoring and location of a route in vivo and a visible image of that route for retrograde perfusion of a tumor with a therapeutic agent and for monitoring treatment procedures during such retrograde perfusion. The data obtained from present and past treatment procedures are stored for analysis and also made available real time to treating physicians during treatment procedures.

Claims

1. A computer-implemented method of monitoring retrograde venous perfusion of a tumor in a patient'"'"'s body, comprising the steps of:

monitoring the positioning of a withdrawal catheter within vasculature of a target vessel in the patient'"'"'s body near the tumor and an infusion catheter within the vasculature of the target vessel extending beyond the withdrawal catheter and near the tumor;

monitoring the positioning of a venous pressure catheter within the vasculature of the target vessel intermediate the infusion catheter and the withdrawal catheter forming a closed loop flow path between the positioned infusion catheter and the positioned withdrawal catheter through the target vessel;

monitoring venous pressure in the closed loop flow paths; and

monitoring the circulation of a fluid through the closed loop flow path.

2. The computer-implemented method of claim 1, further including the step of:

entering data results of at least one of the steps of monitoring into a database.

3. The computer-implemented method of claim 2, wherein the database includes a local database.

4. The computer-implemented method of claim 3, wherein the database includes a central database in communication with the local database.

5. The computer-implemented method of claim 2, further including the step of retrieving from the database available data concerning the patient.

6. The computer-implemented method of claim 2, further including the step of:

recalling data from the database during the retrograde perfusion.

7. The computer-implemented method claim 6, further including the step of:

displaying the recalled data to the treating physician.

8. The method of claim 1, wherein the fluid in the step of circulating is a saline fluid, and further including the step of:

establishing that the closed loop flow path is achieved.

9. The computer-implemented method of claim 8, further including the step of:

circulating a dye-containing solution through the closed loop flow path subsequent to the step of establishing.

10. The computer-implemented method of claim 9, further including the step of:

forming a visible image of the established closed loop flow path

11. The computer-implemented method of claim 10, further including the step of:

storing data in the database data representing the visible image formed of the established closed loop flow path

12. The computer-implemented method of claim 8, further including the step of:

circulating a therapeutic solution through the closed loop flow path subsequent to the step of establishing.

13. The computer-implemented method of claim 12, wherein the therapeutic solution is a chemotherapeutic agent.

14. The computer-implemented method of claim 13, further including the step of:

forming a visible image of the flow of the chemotherapeutic agent through the closed loop flow path.

15. The computer-implemented method of claim 14, further including the step of:

storing data in the database representing the flow of the therapeutic agent through the closed loop flow path.

16. The computer-implemented method of claim 13, further including the step of:

storing data in the database regarding the treatment of the tumor through circulation of the therapeutic solution.

17. The computer-implemented method of claim 1, further including the steps of:

displaying the results of at least one of the steps of monitoring during the retrograde venous perfusion.

18. A data processing system for monitoring retrograde venous perfilsion therapy of a tumor in a patient'"'"'s body as the therapy is occurring, the data processing system comprising:

a processor for performing the steps of;

monitoring the positioning of a withdrawal catheter within vasculature of a target vessel in the patient'"'"'s body near the tumor and an infusion catheter within the vasculature of the target vessel extending beyond the withdrawal catheter and near the tumor;

monitoring the positioning of a venous pressure catheter within the vasculature of the target vessel intermediate the infusion catheter and the withdrawal catheter forming a closed loop flow path between the positioned infusion catheter and the positioned withdrawal catheter through the target vessel;

monitoring venous pressure in the closed loop flow paths;

monitoring the circulation of a fluid through the closed loop flow path; and

a data output display for providing the results of monitoring by the processor.

19. A computer program product stored in signal bearing media for causing a data processor to monitor retrograde venous perfusion on therapy of a tumor in a patient'"'"'s body as the therapy is occurring, the computer program product containing instructions stored in machine-readable code and causing the processor to perform the following steps:

monitoring the positioning of a withdrawal catheter within vasculature of a target vessel in the patient'"'"'s body near the tumor and an infusion catheter within the vasculature of the target vessel extending beyond the withdrawal catheter and near the tumor;

monitoring the positioning of a venous pressure catheter within the vasculature of the target vessel intermediate the infusion catheter and the withdrawal catheter forming a closed loop flow path between the positioned infusion catheter and the positioned withdrawal catheter through the target vessel;

monitoring venous pressure in the closed loop flow paths; and

monitoring the circulation of a fluid through the closed loop flow path.
