Medical device for treatment of a sinus and/or an ear and methods of use thereof

A medical device for treating and/or diagnosing a sinus and/or ear condition, said medical device comprising:

• a housing comprising or functionally connected to:
• a hollow cannula defining a lumen extending at least partially along the length thereof, the cannula is configured to be at least partially inserted through an ostium into a sinus cavity/ear of a subject;
• and
• a flexible grinding wire movable within the cannula's lumen and configured to be inserted into and retrieved out of the sinus cavity through the cannula's lumen, and to rotate along a longitudinal axis thereof and thereby grind, chop and/or stir material present in said sinus cavity and/or inside said hollow cannula, wherein the cannula is in fluid flow communication with an irrigation/aspiration source;
• and
• a wire handle functionally connected to the wire, allowing a user to advance and retrieve the wire within the cannula and into and out of the cannula lumen,
• wherein the device is handheld by a gripping handle.

A medical kit for treating and/or diagnosing a sinus or an ear condition, the kit comprising:

• a device comprising:
• a housing comprising or functionally connected to:
• a hollow cannula defining a lumen extending at least partially along the length thereof, the cannula is configured to be at least partially inserted through an ostium into a sinus cavity/ear of a subject;
• and
• a flexible grinding wire movable within the cannula's lumen and configured to be inserted into and retrieved out of the sinus cavity through the cannula's lumen, and to rotate along a longitudinal axis thereof and thereby grind, chop and/or stir material present in said sinus cavity and/or inside said hollow cannula, wherein the cannula is in fluid flow communication with an irrigation/aspiration source;
• a wire handle functionally connected to the wire, allowing a user to advance and retrieve the wire within the cannula and into and out of the cannula lumen;
• and
• a guiding tube configured to house the cannula therein and bend the cannula as it is being advanced forward, and direct a distal end of the cannula towards a sinus opening, wherein the device is handheld by a gripping handle;
• a connector configured for replacing of guiding tubes;
• and
• a set of replaceable guiding tubes having different angles at a distal section thereof for fitting to different sinus anatomies.

A method for treating and/or diagnosing a sinus or an ear condition, the method comprising:

• utilizing a device comprising a housing comprising or functionally connected to:
• a hollow cannula defining a lumen extending at least partially along the length thereof, the cannula is configured to be at least partially inserted through an ostium into a sinus cavity/ear of a subject;
• and
• a flexible grinding wire movable within the cannula's lumen and configured to be inserted into and retrieved out of the sinus cavity through the cannula's lumen, and to rotate along a longitudinal axis thereof and thereby grind, chop and/or stir material present in said sinus cavity and/or inside said hollow cannula, wherein the cannula is in fluid flow communication with an irrigation/aspiration source;
• a wire handle functionally connected to the wire, allowing a user to advance and retrieve the wire within the cannula and into and out of the cannula lumen;
• and a guiding tube configured to house the cannula therein and bend the cannula as it is being advanced forward, and direct a distal end of the cannula towards a sinus opening, wherein the device is handheld by a gripping handle,
• advancing a distal end of the guiding tube towards the ostium;
• operating the cannula handle to advance the cannula within a guiding tube and through the ostium into a cavity of the sinus/ear;
• operating the wire handle to distally advance the wire out of the cannula and into the sinus cavity;
• and
• activating the motor to induce rotation of the wire.
