Abstract

A multi-lumen, multi-functional catheter system comprising a plurality of axial lumens, at least one lumen supporting a functionality other than material delivery and material removal.

Claims

1. A multi-lumen, multi-functional catheter system comprising a plurality of axial lumens, at least one lumen supporting material delivery of primary treatment chemistry to a point of release and a second lumen having a component supporting a functionality electrostatically near the point of release other than material delivery and material removal wherein at least one biological or physiological measuring device is present within at least one lumen in which information from said at least one biological or physiological measuring device is connected to a host computer and said information is received by said host computer, wherein the component provides information other than information from said at least one biological or physiological measuring device and the component is connected to a host computer and said information is received by said host computer.

2. The system of claim 1 wherein said component is also attached to said catheter system.

3. The system of claim 2 wherein the component measures at least one vital sign of a patient.

4. The system of claim 1 wherein material delivery comprises drug delivery.

5. The system of claim 1 wherein material delivery is into tissue.

6. A multi-lumen, multi-functional catheter system comprising a plurality of axial lumens, at least one lumen supporting a functionality other than material delivery and material removal wherein at least one biological or physiological measuring device is present within at least one lumen in which information from said at least one biological or physiological measuring device is connected to a host computer and said information is received by said host computer, wherein a component that provides information other than information from said at least one biological or physiological measuring device is connected to a host computer and said information is received by said host computer, said component is also attached to said catheter system and the component measures a at least one vital sign of a patient, and wherein information from more than one information source is received by the host computer and a treatment planning and control algorithm is present in said host computer to process that information from more than one source.

7. A method of treating a patient according to a treatment plan comprising inserting a catheter system comprising a multi-lumen, multi-functional catheter system comprising a plurality of axial lumens, at least one lumen supporting material delivery of primary treatment chemistry to a point of release and a second lumen having a component supporting a functionality electrostatically near the point of release other than material delivery and material removal a functionally other than material delivery and material removal into a patient, delivering therapy to the patient through the at least one lumen of said catheter system, the therapy comprising material delivery of primary treatment chemistry, taking information of biological or physiological measurements of tissue or fluids within the patient, reporting said information to a computer, and evaluating performance of the treatment plan with the computer based upon comparing said information to expected biological or physiological information.

8. The method of claim 7 wherein information relating to at least two different biological or physiological measurements are electrically transmitted to the computer for evaluating performance of the treatment plan.

9. The method of claim 8 wherein upon evaluation of the performance of the treatment plan as an existing treatment plan, the computer indicates a deviation for a range of acceptable levels of performance of the treatment plan, and an alteration of the existing treatment plan is identified.

10. The method of claim 9 wherein the computer signals the catheter system to actively modify the existing treatment plan.

11. The method of claim 9 wherein the computer signals an operator to actively modify the existing treatment plan.

12. The method of claim 7 wherein upon evaluation of the performance of the treatment plan, the computer indicates a deviation for a range of acceptable levels of performance of the treatment plan, and an alteration of an existing treatment plan is identified.

13. The method of claim 12 wherein the computer signals the catheter system to actively modify the existing treatment plan.

14. The method of claim 9 wherein the computer signals an operator to actively modify the existing treatment plan.

15. The system of claim 7 wherein material delivery comprises drug delivery.

16. The system of claim 7 wherein material delivery is into tissue.

17. A multi-lumen, multi-functional catheter system comprising a plurality of axial lumens, at least one lumen providing material delivery of primary treatment chemistry to a point of release and a second lumen having a component supporting a functionality electrostatically near the point of release other than material delivery and material removal, delivering therapy to the patient through the at least one lumen of said catheter system, the therapy comprising material delivery of primary treatment chemistry, wherein at least one biological or physiological measuring device is present within at least one lumen in which information from said at least one biological or physiological measuring device is connected to a host computer and said information is received by said host computer wherein at least one biological or physiological measuring device is connected to a signal receiving device by an electrical lead associated with the catheter system, the multi-functional catheter system generating a medical response profile using a general purpose computer system wherein said multi-functional catheter system further comprises a central processing unit, dynamic memory, static memory, a display device, input and output devices, mass storage devices, software, user interfaces, and user control devices.

18. The system of claim 17 wherein the computer contains a program with a treatment planning and therapy algorithm tailored to the need of an individual patient.

19. The system of claim 18 wherein said program with a treatment planning and therapy algorithm can be either adaptively adjusted by at least one controller selected from the group consisting of the computer itself as the therapy progresses, monitoring by a remote station and adjusted by health care professionals, and by an automated system at the remote location as the therapy progresses.

20. The system of claim 17 wherein material delivery comprises drug delivery.

21. The system of claim 17 wherein material delivery is into tissue.
