Abstract
A system for dilating the sinus ostia with a device including a series of elongated members, each having a central channel and increasing outer diameters where the members are positioned one over the other such that the members are advanced to incrementally dilate the sinus ostia. The central channels of each member allow for various procedures to be performed including, for example, the application of wireless energy (e.g., ultrasonic, RF, etc.) to the sinus ostia, the introduction of an irrigating fluid and aspiration from the sinus ostia, and the introduction of a drug to the sinus ostia.
Claims41
A method for dilating the sinus ostia comprising the steps of:
- inserting a first distal end of a first elongated body portion of a first member into the sinus ostia of a patient, the first member including a handle to be gripped by a user and a first channel in the first elongated body portion;
- advancing the first elongated body portion into the sinus ostia and actuating a control on the handle to deflect the first elongated body portion during the advancement;
- advancing a second distal end of a second elongated body portion of a second member over top of the first member such that the first member passes through a second channel of the second member, the second elongated body deflecting along the path of the first elongated body portion;
- advancing a third distal end of a third elongated body portion of a third member over top of the second member such that the second member passes through a third channel of the third member, the third elongated body deflecting along the path of the second elongated body portion.

A device for dilating the sinus ostia comprising:
- a first member including:
- a first elongated body portion adapted to be inserted into the sinus ostia of a patient, said first elongated body portion having a first proximal end and a first distal end defining a first length, the first distal end being deflectable, said elongated body portion having a first channel therein extending from the first proximal end to the first distal end;
- a handle coupled to said first proximal end, said handle including a deflection control for deflection of the first distal end;
- a second member including:
- a second elongated body portion adapted to be inserted into the sinus ostia, said second elongated body portion having a second proximal end and a second distal end defining a second length, the second distal end being deflectable, said second elongated body portion having a second channel therein extending from the second proximal end to the second distal end;
- wherein said first member is longitudinally moveable within the second channel;
- a third member including:
- a third elongated body portion adapted to be inserted into the sinus ostia, said third elongated body portion having a third proximal end and a third distal end defining a third length, the third distal end being deflectable, said third elongated body portion having a third channel disposed therein extending from the third proximal end to the third distal end;
- wherein said second member is longitudinally moveable within the third channel.

A device for dilating the sinus ostia comprising:
- a first member including:
- a first elongated body portion adapted to be inserted into the sinus ostia of a patient, said first elongated body portion including:
- a first proximal end and a first distal end defining a first length, the first distal end being deflectable;
- a first channel therein extending from the first proximal end to the first distal end;
- a handle coupled to the first proximal end, said handle including a deflection control for deflection of the first distal end and a lever positioned on said handle, the lever connected to said handle at a pivot point and having a protrusion extending therefrom;
- at least one indentation positioned on an exterior surface of said first member;
- wherein upon depression of the lever, the lever is rotated about the pivot point and the protrusion interacts with said at least one indentation translating rotational movement of the lever into linear displacement of said first member relative to said handle;
- a second member including:
- a second elongated body portion adapted to be inserted into the sinus ostia, said second elongated body portion having a second proximal end and a second distal end defining a second length, the second distal end being deflectable, said second elongated body portion having a second channel therein extending from the second proximal end to the second distal end;
- wherein said second member is longitudinally moveable with respect to said first member.
