Abstract:
1. A method for diagnosing or treating a disorder of a paranasal sinus or paranasal sinus ostium of a human or animal subject by delivering a diagnostic or therapeutic substance into the paranasal sinus or paranasal sinus ostium, said method comprising: causing a portion of a substance delivery device to be implanted in the paranasal sinus or paranasal sinus ostium, wherein the substance delivery device comprises: introducing the substance through the tube and into the reservoir while the reservoir is implanted such that its intrasinus portion is in the paranasal sinus and its intraostial portion is within the paranasal sinus ostium of that paranasal sinus, thereby causing the reservoir to assume the expanded configuration and resulting in subsequent passage of the substance through the barrier and out of the reservoir; removing the fill tube from the reservoir and withdrawing the fill tube from the paranasal sinus or paranasal sinus ostium; and leaving the reservoir implanted for a period of time sufficient for substance passing through the barrier and out of the reservoir to have an intended diagnostic or therapeutic effect on the paranasal sinus or paranasal sinus ostium.
