1. A method of delivering oxygen to a target tissue in the lung of a patient, the method comprising:
- locating a target site on an airway wall;
creating an opening through the airway wall at the target site with a piercing member;
advancing an elongate instrument through the opening to the target tissue, said elongate instrument comprising an access lumen; and
delivering oxygen through the access lumen to the target tissue to increase the oxygen in the target tissue, and wherein the target tissue is a tumor.

Abstract
Methods and devices for diagnosing, monitoring, and/or treating tissue through an opening or port through an airway wall. A passageway is created extending from the airway to the target tissue. The passageway provides local access to the target tissue for treatment instruments and for delivering agents.

8. A method of delivering oxygen to a target tissue in the lung of a patient, the method comprising:
- locating a target site on an airway wall;
creating an opening through the airway wall at the target site with a piercing member; advancing an elongate instrument through the opening to the target tissue, said elongate instrument comprising an access lumen; deploying a shunt through the access lumen to create a passageway extending from the airway to the target tissue such that oxygen of the target tissue is increased by being in fluid communication with the airway; withdrawing the elongate instrument from the patient; and treating the target tissue while the target tissue has increased oxygen. - View Dependent Claims (9)
