Abstract

Inventive embodiments disclosed herein include a catheter for dilating a sinus cavity lumen. The catheter includes a guide tube, having a proximal end and a distal end, that terminates in a distal tip; a sleeve member annularly positioned over the guide tube, wherein the sleeve member is movable relative to the guide tube and is capable of being advanced over the guide tube; and a balloon coupled to the sleeve member, wherein the balloon can be extendable and inflated at or beyond the end of the guide tube.

Claims

1. A device for dilating a sinus cavity lumen, comprising:

a guide tube, having a proximal end and a distal end, the distal end terminating in a distal tip, a distal portion of the guide tube being malleable;

a sleeve member annularly positioned over the guide tube, wherein the sleeve member is movable relative to the guide tube and is capable of being advanced over the guide tube and past the distal tip;

a balloon coupled to the sleeve member, wherein the balloon is extendable and inflatable at or beyond the distal tip of the guide tube;

a guidewire extending through the guide tube and terminating at a point distal with respect to the guide tube, wherein the sleeve member comprises a distal sleeve portion having a diameter smaller than a proximal sleeve portion yet slightly larger than an outer diameter of the guidewire; and

a handle disposed along a proximal portion of the guide tube, the handle comprising a knob moveable in a distal direction relative to the handle and operatively coupled to the sleeve member, wherein distal advancement of the knob advances the sleeve member and balloon over the guide tube in a distal direction.

2. The device of claim 1, wherein the sleeve comprises a chamfered proximal end.

3. The device of claim 1, wherein at least a portion of the guide tube is deflectable.

4. The device of claim 1 wherein the distal end of the guide tube is malleable and the proximal end of the guide tube is rigid.

5. The device of claim 1, further comprising an endoscopic element.

6. The device of claim 1, further comprising an aspirating element.

7. The device of claim 1, further comprising an extendable member that extends the tip of the guide tube.

8. The device of claim 1, wherein the balloon is positionable and inflatable past the end of the guide tube.

9. The device of claim 1, wherein the handle further comprises a second knob, the second knob effective for moving an extension to the guide tube.

10. The device of claim 1, wherein the sleeve member may be positioned in a fully extended state and a fully retracted state.

11. The device of claim 10, wherein the balloon is positioned at the distal tip or distal from the distal tip when the sleeve is in the fully retracted state.

12. The device of claim 1, wherein the guidewire is a light-emitting guidewire.

13. The device of claim 1, wherein the distal sleeve portion and an inner surface of the balloon are made of material that is more compliant than the guidewire.

14. A device for dilating a sinus cavity lumen, comprising:

a guide tube, having a proximal end and a distal end, the distal end terminating in a distal tip, a distal portion of the guide tube being malleable;

a sleeve member annularly positioned over the guide tube, wherein the sleeve member is movable relative to the guide tube and is capable of being advanced over the guide tube and past the distal tip;

a balloon coupled to the sleeve member, wherein the balloon is extendable and inflatable at or beyond the distal tip of the guide tube;

an elongate member extending from a distal end of the sleeve;

a handle disposed along a proximal portion of the guide tube, the handle comprising a knob moveable in a distal direction relative to the handle and operatively coupled to the sleeve member, wherein distal advancement of the knob advances the sleeve member and balloon over the guide tube in a distal direction.

15. The device of claim 14, wherein the elongate member is malleable.

16. The device of claim 14, wherein the elongate member is flexible or compliant.
