Medical device and method for treatment of a sinus opening
First Claim
1. A medical device for the treatment of a sinus opening, the medical device comprising:
- a handle with;
a proximal end;
a distal end; and
a longitudinal axis along the length of the handle;
a guide wire;
a guide catheter attached to the distal end of the handle, the guide catheter having a guide catheter lumen;
a guide wire movement mechanism operatively disposed on the handle;
a balloon catheter;
anda balloon catheter movement mechanism operatively disposed on the handle;
wherein the handle and the guide catheter lumen are configured for operatively accepting the guide wire and the balloon catheter; and
wherein the guide wire movement mechanism is configured for advancement and retraction of the guide wire disposed at least partially in the handle and the guide catheter lumen through the handle and the guide catheter lumen by user operation of the guide wire movement mechanism; and
wherein the guide wire movement mechanism includes an integrated guide wire locking and rotation mechanism configured for rotation of the guide wire by rotation of the guide wire locking and rotation mechanism relative to the guide wire movement mechanism and the handle, and for securely locking and unlocking the guide wire to the guide wire movement mechanism; and
wherein the guide wire movement mechanism comprises a proximal end and a distal end and a longitudinal axis between the proximal end and the distal end, said guide wire movement mechanism configured to direct the guide wire along the longitudinal axis of guide wire movement mechanism from the proximal end to the distal end of the guide wire movement mechanism and in a direction that is not along the longitudinal axis into the handle distal to the distal end of the guide wire movement mechanism; and
wherein the balloon catheter movement mechanism is configured for advancement and retraction of the balloon catheter disposed at least partially in the handle and in the guide catheter lumen through the handle and guide catheter lumen by user operation of the balloon catheter movement mechanism.

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 guide wire and balloon catheter are both disposed at least partially in the handle and catheter lumen. 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. 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. 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.
