Abstract

Devices and methods for delivering substances to lung tissue through an extra-anatomic passage created in an airway.

Claims

1. A method for performing a procedure on a target tissue in a lung of a patient located outside of an airway lumen, the method comprising:

advancing a tubular structure through the airway lumen of the patient, the airway lumen comprising a tissue lumen wall;

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.

2. 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.

3. The method of claim 1, wherein the tool is a forceps.

4. The method of claim 1, wherein the procedure is a biopsy.

5. The method of claim 1, wherein the target tissue is a tumor.

6. The method of claim 1, wherein the tubular structure is a flexible elongate tubular member.

7. The method of claim 1, wherein the tubular structure is rigid.

8. 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.

9. The method of claim 8, further comprising mechanically maintaining the patency of the opening by inserting the tubular structure into the opening.

10. The method of claim 1, further comprising mechanically maintaining the patency of the opening, thereby forming an open channel.

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.

12. The method of claim 11, wherein the procedure is a biopsy.
