Abstract

A system for manipulating a guide catheter within a patient'"'"'s nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.

Claims

1. A system for placing a wire guide in a sinus drainage pathway in a patient comprising:

a guide catheter;

a handle secured to a proximal portion of the guide catheter, the handle defining a recess that opens along a longitudinal length of an exterior portion of the handle;

a wire steering device disposed in the recess and configured to slide along the recess in a direction parallel to a major longitudinal axis of the handle and further configured to rotate relative to the handle, wherein the wire steering device is configured to be externally manipulated by a user; and

a wire guide extending through the guide catheter and the wire steering device, wherein the wire steering device is configured to effectuate rotation of the wire guide through complete revolutions relative to the handle while the wire steering device is positioned within the steering device recess; and

a balloon catheter comprising an inflatable balloon, wherein the balloon catheter is configured to extend over the wire guide for placement in the sinus drainage pathway.

2. The system of claim 1, wherein the handle includes a hub recess that is removably secured to a hub of the guide catheter.

3. The system of claim 2, wherein the hub recess is located at a position that is distal relative to the recess in the handle.

4. The system of claim 2, wherein the handle defines a wire recess at a position that is proximal to the hub recess and distal to the recess in the handle.

5. The system of claim 4, further comprising a second wire recess disposed in the handle and located proximal the recess in the handle.

6. The system of claim 5, wherein the wire guide extends distally from a distal end of the guide catheter and extends proximally from the second wire recess.

7. The system of claim 2, wherein the guide catheter is releasably secured to the hub recess by at least one of detents or tabs.

8. The system of claim 1, wherein a distal portion of the handle is releasably secured to the proximal portion of the guide catheter with a frictional fit.

9. The system of claim 1, wherein an exterior surface of the steering device is at least one of scored, roughened, or textured.

10. The system of claim 1, wherein the wire guide comprises a curved tip.

11. The system of claim 1, wherein the wire guide comprises a plurality of spaced apart markers.

12. The system of claim 1 further comprising a light emitting elongate member configured to emit light within a sinus cavity.

13. The system of claim 12, wherein the light emitting elongate member is a fiber optic catheter disposed over the wire guide.

14. The system of claim 12, wherein the emitted light has a brightness sufficient to be viewed external to the patient to confirm the location of the wire guide within the sinus cavity.

15. The system of claim 1, further comprising a directable endoscope.

16. The system of claim 15, wherein the directable endoscope comprises a knob disposed thereon and configured to direct a viewing field of the endoscope.
