selecting a location along the airway lumen to create an opening through the tissue lumen wall; creating an incision at the location with a wire member; enlarging the incision with an inflatable member to form the opening; advancing the tubular structure into the opening; advancing a tool through the opening and through the passageway in the tubular structure towards the target tissue within the parenchyma; and performing a procedure on the target tissue in the parenchyma with the tool. ### Claim 2 (depends on 1) The method of claim 1, wherein the tool is selected from the group consisting of a substance delivery catheter, an ablation device, a biopsy device, and an imaging device. ### Claim 3 (depends on 1) The method of claim 1, wherein the tool is a forceps. ### Claim 4 (depends on 1) The method of claim 1, wherein the procedure is a biopsy. ### Claim 5 (depends on 1) The method of claim 1, wherein the target tissue is a tumor. ### Claim 6 (depends on 1) The method of claim 1, wherein the tubular structure is a flexible elongate tubular member. ### Claim 7 (depends on 1) The method of claim 1, wherein the tubular structure is rigid. ### Claim 8 (depends on 1) The method of claim 1, wherein advancing the tubular structure through the airway lumen comprises advancing the tubular structure through a branching structure of airways. ### Claim 9 (depends on 8) The method of claim 8, further comprising mechanically maintaining the patency of the opening by inserting the tubular structure into the opening. ### Claim 10 (depends on 1) The method of claim 1, further comprising mechanically maintaining the patency of the opening, thereby forming an open channel. ### Claim 11 A method for performing a procedure on a target tissue of a lung of a patient located outside of an airway lumen within a parenchyma of the lung, the method comprising: selecting a location along the airway lumen to create an access point through a tissue lumen wall; delivering energy to the location to create an incision at the location; enlarging the incision to form the access point; inserting a tubular structure in the access point, the tubular structure comprising an open channel to establish the access point to the target tissue within the parenchyma; and advancing a tool through the open channel, and towards the target tissue; and performing a procedure on the target tissue within the parenchyma with the tool. ### Claim 12 (depends on 11) The method of claim 11, wherein the procedure is a biopsy.
