Abstract
The present disclosure generally relates to the field of medical devices for treatment and diagnosis of paranasal sinus conditions and methods of using same. There is disclosed a device having a hollow shaft configured to be inserted into a paranasal sinus through a natural opening thereof. The hollow shaft is shaped/configured to reach a treatment area within the paranasal sinus.
Claims36
A medical device for treating and/or diagnosing a paranasal sinus condition, said medical device comprising:
- a flexible hollow cannula configured to be at least partially inserted through an ostium into a sinus cavity of a subject, said flexible hollow cannula comprising a flexible grinding wire configured 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.

A method for treating and/or diagnosing a paranasal sinus condition, said medical device comprising:
- inserting, at least partially, a flexible hollow cannula through an ostium into a sinus cavity of a subject, the flexible hollow cannula comprising a flexible grinding wire;
- activating rotation of the grinding wire along a longitudinal axis thereof, thereby grinding, chopping and/or stirring material present in the sinus cavity and/or inside said hollow cannula;
- and
- conducting irrigation and/or aspiration during the rotation of the grinding wire.

A medical system for treating and/or diagnosing a paranasal sinus condition, said medical device comprising:
- a flexible hollow cannula configured to be at least partially inserted through an ostium into a sinus cavity of a subject, said flexible hollow cannula comprising a flexible grinding wire configured 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;
- an elongated tubular member configured to receive said flexible hollow cannula, wherein said elongated tubular member comprises a distal end being bent or bendable so as to face the ostium of the paranasal sinus, once inserted into the subject's nose;
- and
- a handle mechanically connected to the tubular member at a proximal end thereof, the handle is configured to control movement and extension of the hollow cannula, the handle comprises a pumping-orifice configured to provide fluid to the hollow cannula, and a suction-orifice configured to provide suction from the hollow cannula.
