Abstract

A medical device for the treatment and irrigation of a sinus opening is described. The device allows for single-handed operation to access, dilate and irrigate a sinus opening. The device includes a sinus guide catheter, a guiding element, a balloon dilation catheter, a balloon catheter movement mechanism and a guiding element movement mechanism. A method for treating a sinus opening and irrigating a sinus is also described.

First claim

What is claimed is:

1. A medical device for accessing and dilating a passageway in a head of a patient, the device comprising:
(a) a handle having a distal end;
(b) a guide shaft attached to the distal end of the handle;
(c) a guiding element for accessing a passageway in a head of a patient, the guiding element being slidable relative to the guide shaft;
(d) a dilation catheter for dilating the passageway in the head of the patient, the dilation catheter being slidable relative to the guide shaft;
(e) a dilation catheter actuator slidable along the handle; and
(f) a guiding element actuator slidable along the handle;
wherein the dilation catheter actuator and the guiding element actuator are slidable along the handle for single handed movement of the guiding element and dilation catheter to access and dilate the passageway in the head of the patient without removing the medical device from the head of the patient;
wherein the guiding element actuator and the dilation catheter actuator are longitudinally aligned;
wherein the dilation catheter actuator is located on top of the guiding element actuator and is configured to slide over the guiding element actuator.

2. The medical device of claim 1 , wherein the dilation catheter comprises an inflation lumen.

3. The medical device of claim 1 , wherein the dilation catheter comprises a guiding element lumen.

4. The medical device of claim 1 , wherein the handle further has a proximal end and a handle body between the proximal end the distal end.

5. The medical device of claim 1 , wherein the dilation catheter actuator is configured for advancement or retraction of the dilation catheter relative to the handle using a single finger or thumb.

6. The medical device of claim 5 , wherein the dilation catheter actuator is configured for advancement or retraction of the dilation catheter relative to the guide shaft using a single finger or thumb.

7. The medical device of claim 1 , wherein the guiding element actuator is configured for advancement or retraction of the guiding element relative to the handle and guide shaft using a single finger or thumb.

8. The medical device of claim 1 , wherein the guiding element actuator is further configured for rotation of the guiding element.

9. The medical device of claim 1 , wherein the guiding element includes at least one of a guidewire or a sinus illumination system.

10. The medical device of claim 1 , wherein the dilation catheter actuator and the guiding element actuator are slidable along the handle independently from each other.

11. The medical device of claim 1 , wherein the dilation catheter actuator and the guiding element actuator are each slidable along the handle within a same range of motion.

12. A medical device for accessing and dilating a passageway in a head of a patient, the device comprising:
(a) a guide shaft;
(b) a guiding element;
(c) a guiding element actuator;
(d) a dilation catheter comprising:
(i) a proximal end,
(ii) a distal end, and
(iii) a shaft system between the proximal end and the distal end, the shaft system having a dilation catheter actuator located on top of the guiding element actuator and configured to slide over the guiding element actuator.

13. The medical device of claim 12 , wherein the shaft system has a proximal shaft section and a distal shaft section, wherein the proximal shaft section comprises the dilation catheter actuator.

14. The medical device of claim 13 , wherein the distal shaft section comprises an inflatable balloon.

15. The medical device of claim 12 , wherein the guiding element includes at least one of a guidewire or a sinus illumination system.

16. The medical device of claim 12 , wherein the dilation catheter actuator and the guiding element actuator are each longitudinally translatable relative to the guide shaft.

17. The medical device of claim 16 , wherein the dilation catheter actuator and the guiding element actuator are translatable independently from each other relative to the guide shaft.

18. The medical device of claim 12 , wherein the dilation catheter actuator and the guiding element actuator are each translatable within a same range of longitudinal motion.

19. A dilation catheter for the treatment of a passageway in a head of a patient, the dilation catheter comprising:
(a) a proximal end;
(b) a distal end; and
(c) a shaft system between the proximal end and the distal end, the shaft system having a dilation catheter actuator, wherein the dilation catheter actuator includes a U-shaped cavity sized and configured to slidably receive a guiding element actuator such that the dilation catheter actuator is configured to be located on top of the guiding element actuator and to slide over the guiding element actuator.

20. The dilation catheter of claim 19 , wherein the shaft system further has an inflation lumen.
