Systems, instruments and methods for treating sinuses

A method for treating a sinus of a subject, the method comprising:

• providing an instrument including:
• a base configured to be gripped by an operator;
• an elongate probe including a probe proximal end coupled with the base and extending to a probe distal end, the probe including:
• an aspiration lumen terminating at an inlet port proximate the probe distal end;
• and
• a delivery lumen terminating at an outlet port proximate the probe distal end;
• a dilation balloon mounted on and surrounding a portion of the probe proximate the probe distal end, wherein the dilation balloon is expandable into an expanded configuration to execute a dilation operation;
• and
• a waveguide on the probe and having a light emitting end proximate the probe distal end;
• wherein:
• the instrument includes an integral aspiration controller operable to selectively control fluid flow between a suction source and the aspiration lumen,
• wherein the integral aspiration controller is mounted on the base;
• the probe defines a probe longitudinal axis from the probe proximal end to the probe distal end;
• the base includes a handle configured to be gripped by a hand of the operator;
• the handle has a handle axis extending at a transverse angle to the probe longitudinal axis;
• and
• the integral aspiration controller includes a trigger mounted on the base and operable by the operator's hand while gripping the handle to selectively control fluid flow between the suction source and the aspiration lumen;
• operating the trigger to execute an aspiration operation wherein the instrument system draws material into the aspiration lumen through the inlet port;
• executing a fluid delivery operation wherein the instrument system flows a fluid through the delivery lumen and out through the outlet port;
• and
• executing an illumination operation wherein the instrument system transmits light through the waveguide and out through the light emitting end.

• and
• a waveguide on the probe and having a light emitting end proximate the probe distal end;
• wherein:
• the probe includes a rigid, elongate shaft;
• the aspiration lumen and the delivery lumen extend through the shaft;
• the dilation balloon is mounted on and surrounds a portion of a distal end portion of the shaft;
• and
• a distal end portion of the waveguide extends longitudinally along the shaft and radially between the dilation balloon and an outer surface of the shaft.
