Methods and devices for diagnosing, monitoring, or treating medical conditions through an opening through an airway wall
First Claim
Patent Images
1. A method of treating a target tissue in a parenchymal tissue of a 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;
advancing an elongate instrument through the opening to the target tissue, said elongate instrument comprising an access lumen;
advancing a light delivery instrument through the access lumen and through the opening into the parenchyma to the target tissue in the parenchymal tissue of the lung;
administering a photosensitive drug to the patient; and
directing a beam of light locally at the target tissue, while minimizing collateral damage to surrounding tissue, such that the light activates the photosensitive drug at the target tissue.

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.

12. A method of treating a target tissue within a parenchyma in a 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; advancing an elongate instrument through the opening to the target within the parenchyma, said elongate instrument comprising an access lumen; advancing a delivery catheter through the access lumen; administering a photosensitive drug to the target tissue through the delivery catheter; and directing a beam of light to the target tissue while minimizing collateral damage to surrounding tissue, such that the light activates the photosensitive drug at the target tissue within the parenchyma. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
