Abstract:
1. A method of regulating air flow for a targeted lung region comprising a segment or lobe of the lung, comprising: selecting a patient having a collateral pathway in the lung; providing a mixture formed of a sclerosing agent selected from the group consisting of tetracycline, doxycycline, and minocycline and a substance having properties such that the substance is absorbed into lung tissue over a period of time; reducing collateral air flow that flows through the collateral pathway between the targeted lung region and another segment or lobe of the lung by injecting the mixture into the targeted lung region such that the substance causes the sclerosing agent to be released into tissue of the target lung region over a period of time; and after reducing collateral flow to the targeted lung region, reducing direct air flow in a bronchus that provides direct air flow to the targeted lung region.
