Medical device and method for treatment of a sinus opening
First Claim
1. A method for treating a sinus opening, the method comprising:
- (a) inserting a medical device for the treatment of a sinus opening partially into a patient'"'"'s anatomy, wherein the medical device includes;
(i) a handle having a proximal end and a distal end,(ii) a guide wire integrated with the handle,(iii) a guide wire movement mechanism slidably positioned between the proximal end of the handle and the distal end of the handle,(iv) a guide wire locking and rotation mechanism integrated with the guide wire movement mechanism,(v) a balloon catheter, and(vi) a balloon catheter movement mechanism positioned between the proximal end of the handle and the distal end of the handle;
(b) positioning the medical device in the sinus opening;
(c) advancing a guide wire of the medical device into the patient'"'"'s sinus via user operation of the guide wire movement mechanism of the medical device, wherein the balloon catheter movement mechanism and the guide wire movement mechanism remain positioned between the proximal end of the handle and the distal end of the handle during the act of advancing the guide wire;
(d) rotating the guide wire within the patient'"'"'s anatomy via user operation of the guide wire locking and rotation mechanism of the guide wire movement mechanism;
(e) repeating the guide wire advancing and rotating steps to position the guide wire in the sinus opening;
(f) advancing a balloon catheter of the medical device along the guide wire via user operation of the balloon catheter movement mechanism of the medical device, wherein the balloon catheter movement mechanism and the guide wire movement mechanism remain positioned between the proximal end of the handle and the distal end of the handle during the act of advancing the balloon catheter; and
(g) treating the sinus opening via inflation of the balloon catheter.

Abstract
A medical device and method for the treatment of a sinus opening includes a handle, a guide catheter, a guide wire, a balloon catheter, a guide wire movement mechanism and a balloon catheter movement mechanism. The handle has proximal and distal ends and a longitudinal axis along the length of the handle. The guide catheter is attached to the distal end of the handle and has a catheter lumen. The guide wire and balloon catheter are both disposed at least partially in the handle and catheter lumen. The guide wire movement mechanism and the balloon catheter movement mechanism are both operatively disposed on the handle. In addition, the guide wire movement mechanism is configured for advancement and retraction of the guide wire through the handle and catheter lumen by user operation of the guide wire movement mechanism. Moreover, the guide wire movement mechanism includes an integrated guide wire locking and rotation mechanism configured for rotation of the guide wire and for securely locking and unlocking the guide wire to the guide wire movement mechanism. Furthermore, the balloon catheter movement mechanism is configured for advancement and retraction of the balloon catheter through the handle and catheter lumen by user operation of the balloon catheter movement mechanism.

17. A method of treating an anatomical passageway within a head of a patient, the anatomical passageway being selected from the group consisting of the nasal anatomy, the paranasal sinus ostium, a paranasal sinus, and a Eustachian tube opening, the method comprising:
-
inserting a guide into a head of a patient, the guide extending distally from a handle assembly of a medical device, the handle assembly including; (i) a body, (ii) a first actuator, the first actuator being integrated with the body, wherein the first actuator is movable relative to the body, (iii) a second actuator, the second actuator being movably coupled with the first actuator such that the second actuator is movable relative to the first actuator and relative to the body, and (iv) a third actuator, the third actuator being integrated with the body, wherein the third actuator is movable relative to the body; advancing a guide wire of the medical device into the head of the patient, the act of advancing a guide wire of the medical device into the head of the patient including moving the first actuator relative to the body of the handle assembly; rotating the guide wire within the head of the patient, the act of rotating the guide wire within the head of the patient including rotating the second actuator relative to the first actuator and relative to the body of the handle assembly; advancing the guide wire into the anatomical passageway, the act of advancing the guide wire into the anatomical passageway including moving the first actuator relative to the body of the handle assembly;
advancing a dilation catheter of the medical device along the guide wire into the anatomical passageway, the act of advancing the dilation catheter of the medical device along the guide wire into the anatomical passageway including moving the third actuator relative to the body of the handle assembly; andexpanding a dilator of the dilation catheter to thereby dilate the anatomical passageway. - View Dependent Claims (18, 19)
