Methods and apparatus for treating disorders of the sinuses

Abstract

A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy, positioning a guide wire operatively extending from a rail of the medical device into a sinus opening of the patient, advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire with a balloon catheter movement mechanism, and inflating the balloon catheter.

Problems solved by technology

Acute sinusitis can be associated with upper respiratory infections or allergic conditions, which may cause tissue swelling and temporarily impede normal trans-ostial drainage and ventilation of the sinuses, thereby resulting in some collection of mucus and possibly infection within the sinus cavities.

Chronic sinusitis, if left untreated, can result in irreparable damage to the tissues and / or bony structures of the paranasal anatomy.
