Balloon dilation catheter system for treatment and irrigation of the sinuses
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.
1. A medical device for accessing, dilating and irrigating a sinus, the device comprising:
a handle useful for single-handed operation of the medical device, said handle having a proximal end, a distal end and a handle body between the proximal end and the distal end;
a sinus guide catheter attached to said handle distal end;
a guiding element for accessing the sinus; and
a balloon dilation catheter for dilating and irrigating the sinus wherein the balloon dilation catheter comprises an inflation lumen, a guiding element lumen and an irrigation lumen;
wherein a balloon catheter movement mechanism and a guiding element movement mechanism are slidable along the handle for single handed movement of the guiding element and balloon catheter to access, dilate and irrigate the sinus without removing the medical device from the sinus, and wherein the guiding element movement mechanism and the balloon catheter movement mechanism are longitudinally aligned and the balloon catheter movement mechanism is located on top of the guiding element movement mechanism and is configured to slide over the guiding element movement mechanism.
2. The medical device of claim 1 wherein the balloon catheter movement mechanism is configured for advancement or retraction of the balloon catheter through the handle and guide catheter using a single finger or thumb.
3. The medical device of claim 1 wherein the guiding element movement mechanism is configured for advancement or retraction of the guiding element through the handle and guide catheter using a single finger or thumb.
4. The medical device of claim 1 wherein the guiding element movement mechanism is further configured for rotation of the guiding element.
5. The medical device of claim 1 wherein the balloon dilation catheter comprises an integrated shaft system.
6. The medical device of claim 5 wherein the integrated shaft system has a proximal portion and a distal portion and the integrated shaft system comprises:
the inflation lumen that extends through the proximal portion and the distal portion;
a combined lumen that comprises the irrigation lumen and the guiding element lumen in the distal portion; and
a coaxial lumen that comprises the irrigation and the guiding element lumens in the proximal portion.
7. The medical device of claim 5 wherein the integrated shaft system has a proximal portion and a distal portion and the integrated shaft system comprises:
the inflation lumen that extends through the proximal portion and the distal portion;
a combined lumen that comprises the irrigation lumen and guiding element lumen in the distal portion; and
a side by side lumen that comprises the irrigation and guiding element lumens in the proximal portion.
8. The device of claim 1 wherein the guiding element is a sinus illumination system.
