Devices and methods for delivering substances to lung tissue through an extra-anatomic passage created in an airway.
1. A method for performing a procedure on a patient at a treatment site in an area of a lung having a suspected diseased tissue beyond and remote from an airway in the lung, the method comprising: creating an opening through an airway wall of the lung with a piercing member;advancing a tubular membe
1. A method for performing a procedure on a patient at a treatment site in an area of a lung having a suspected diseased tissue beyond and remote from an airway in the lung, the method comprising: creating an opening through an airway wall of the lung with a piercing member;advancing a tubular member located about the piercing member into the opening such that a passageway through the tubular member extends through the airway wall;removing the piercing member from the tubular member such that the tubular member remains in the airway wall and the passageway of the tubular member provides an access path to the treatment site;advancing a distal section of a second device through the passageway of the tubular member to access the treatment site in the lung beyond the airway wall, the second device comprising an elongate flexible proximal shaft; andperforming the procedure at the treatment site on the suspected diseased tissue via the second device after advancing the distal section of the second device through the passageway of the tubular member. 2. The method of claim 1, wherein the piercing member is a wire. 3. The method of claim 2, wherein the step of performing the procedure comprises delivering a substance to the treatment site through the second device. 4. The method of claim 2, wherein at least one of the steps is performed through an endoscope. 5. The method of claim 4, wherein the piercing member includes an obturator. 6. The method of claim 1, wherein the step of performing the procedure comprises treating the suspected diseased tissue. 7. The method of claim 6, wherein the suspected diseased tissue is a lung tumor. 8. The method of claim 1, further comprising enlarging the opening with a balloon. 9. The method of claim 2, wherein the step of performing a procedure comprises a biopsy. 10. The method of claim 1, wherein the tubular member is formed of a polymeric material. 11. The method of claim 10, wherein the tubular member is placed using a guide-wire. 12. The method of claim 1, wherein the piercing member comprises a piercing device having a conical tip and a lumen extending therethrough, and an elongate wire extendable past the conical tip, and wherein after the elongate wire creates the opening the conical tip may be driven into the opening gradually expanding the opening to allow the tubular member to be subsequently placed therethrough. 13. A method for performing a procedure in a lung of a patient, the method comprising: non-invasively locating a suspected diseased tissue in the lung and exterior to an airway in the lung;advancing a distal end of an endoscope along an airway to a location within the airway;advancing a piercing member from the distal end of the endoscope through an airway wall of the lung to create an opening;dilating the opening to create an enlarged opening with a dilating member advanced from the distal end of the endoscope;advancing a tubular member from the distal end of the endoscope into the enlarged opening; advancing a catheter member through an access path in the tubular member, the access path extending through the enlarged opening to access the suspected diseased tissue, exterior to the airway wall; andperforming a procedure on the suspected diseased tissue using the catheter member. 14. The method of claim 13, wherein the step of performing the procedure comprises performing a biopsy. 15. The method of claim 13, wherein the catheter member includes an obturator. 16. The method of claim 13, wherein the step of performing the procedure comprises delivering a substance to the suspected diseased tissue.
