Abstract

Balloon catheters, assemblies and systems and methods for using them for the continuous in vivo monitoring of one or more selected analytes or other physiological chemistries within a patient using an implantable analyte sensor associated with a balloon catheter are provided.

Claims

1. A device for in vivo monitoring of one or more selected analytes within a patient, the device comprising:

a catheter comprising a balloon at a distal portion of the catheter; and

at least one analyte sensor associated with the balloon, wherein the at least one analyte sensor is positioned for contact with a bodily fluid when the balloon is operatively deployed within the patient.

2. The device of claim 1 wherein an analyte sensor is provided on an exterior surface of the balloon.

3. The device of claim 1 wherein an analyte sensor is provided on an interior surface of the balloon.

4. The device of claim 1 wherein an analyte sensor is provided on the distal portion of the catheter adjacent the balloon.

5. The device of claim 1 wherein the distal portion of the catheter comprises at least one opening therein for the ingress of bodily fluid therethrough.

6. The device of claim 5 wherein a portion of the catheter proximal to the balloon comprises at least one opening therein for the egress of bodily fluid therethrough.

7. The device of claim 1 wherein at least one analyte sensor is a glucose sensor.

8. The device of claim 1 wherein the catheter is a multi-lumen catheter comprising at least one balloon expansion lumen and at least one lumen for the delivery of an instrument for performing a medical procedure.

9. The device of claim 1 wherein the catheter is configured for performing a therapeutic procedure.

10. The device of claim 1 wherein the catheter is configured for performing a diagnostic procedure.

11. The device of claim 1 wherein the catheter is configured for performing an intravascular procedure.

12. The device of claim 9 wherein the procedure comprises at least one of percutaneous transluminal coronary angioplasty, stent placement, directional coronary atherectomy and cardiac tissue ablation.

13. The device of claim 1 wherein the balloon is configured for expansion against a tissue structure within the patient.

14. A catheter system for performing a procedure within the body, the system comprising:

a balloon catheter comprising at least one analyte sensor associated with a balloon provided at a distal portion of the catheter; and

an analyte monitor in communication with the at least one analyte sensor.

15. The catheter system of claim 14 further comprising at least one tool for delivery through a lumen of the catheter to a target location within the body.

16. The catheter system of claim 15 wherein at least one tool is a guide wire.

17. The catheter system of claim 14 further comprising a wire connection between the analyte monitor and the analyte sensor.

18. The catheter system of claim 14 further comprising a wireless connection between the analyte monitor and the analyte sensor.

19. A catheter system for performing a procedure within the body, the system comprising:

an analyte sensing catheter comprising at least one analyte sensor associated with a balloon provided at a distal portion of the catheter; and

at least a second catheter configured for performing a medical procedure at a target location within the body.

20. The catheter system of claim 19 wherein the at least the second catheter is configured for performing a diagnostic procedure.

21. The catheter system of claim 19 wherein the at least the second catheter is configured for performing a therapeutic procedure.

22. A method for continuously measuring at least one target analyte within the body of a patient, the method comprising:

providing a catheter comprising at least one analyte sensor associated with a balloon provided at a distal portion of the catheter;

delivering the catheter to a location in the body and expanding the balloon at the location wherein the at least one analyte sensor is positioned for contact with a bodily fluid; and

monitoring at least one target analyte in the bodily fluid for a period of time.

23. The method of claim 22 further comprising performing a medical procedure within the body during at least a portion of the period of time the at least one target analyte is monitored.

24. The method of claim 23 wherein monitoring the at least one target analyte comprises determining when the at least one target analyte is within a safe range.

25. The method of claim 24 further comprising performing the medical procedure when the at least one target analyte is within the safe range.

26. The method of claim 23 wherein the medical procedure comprises employing the catheter to perform at least a portion of the procedure.

27. The method of claim 23 wherein the medical procedure is performed proximate the location in the body at which the balloon is expanded.

28. The method of claim 23 wherein the medical procedure comprises at least one of percutaneous transluminal coronary angioplasty, stent placement, directional coronary atherectomy, or cardiac tissue ablation.
