PULMONARY NODULE ACCESS DEVICES AND METHODS OF USING THE SAME
First Claim
1. A device for providing access to a nodule, lesion, or pathological area in a lung or other body organ or lumen, the device comprising:
- a channel portion, the channel portion having a proximal end and a distal end, wherein the channel portion defines a lumen, the lumen extending from the proximal end of the channel portion to the distal end of the channel portion; and
at least one anchor member, the anchor member configured to inhibit rotational, proximal, and distal motion of the channel portion with respect to the nodule upon deployment of the device in a body lumen.

Abstract
In certain embodiments, a device is configured to be delivered to the site of a nodule in the lung or other body organ or lumen. The device can be configured to attach directly to the target nodule or to tissue adjacent the target nodule. The device can be configured to provide repeatable access to the site of the target nodule. In some embodiments, the device includes a guide wire that can extend proximal the device. The guide wire can be configured to engage with a catheter or other medical device to provided repeatable and dependable navigation to the site of the target nodule. In some embodiments, the device can include a channel portion through which medical devices and/or instruments can be navigated. In some embodiments, the device can be deployed in the wall of an airway or other body lumen to provide transluminal access to a nodule outside of the lumen.

21. A method of deploying and using a fiducial device for repeatable access to a nodule in a lung or other body organ, the method comprising:
-
locating a target nodule in the body; compressing the fiducial device within the working channel of a catheter or other delivery device, the fiducial device comprising a fixation portion and a guide portion; navigating the catheter or other delivery device to the site of the target nodule; removing the fiducial device from the working channel of the catheter or other delivery device; attaching the delivery device to tissue proximate the target nodule; removing the catheter or other delivery device from the site of the target nodule; engaging a second catheter or other delivery device with the guide portion of the fiducial device, the second catheter of other delivery device including a treatment or diagnosis instrument; navigating the second catheter or other delivery device along the guide portion of the fiducial device to the site of the target nodule; treating or collecting a sample from the target nodule; and withdrawing the second catheter or other delivery device along the guide portion of the fiducial device.

22. A device for providing access to a nodule in a lung or other body organ or lumen, the device comprising:
-
a fixation portion having a proximal end and a distal end, the fixation portion comprising one or more anchor portions, the fixation portion configured to be attached to tissue in substantially constant proximity to the nodule; and a guide portion having a proximal end and a distal end, the guide portion configured to removably engage with a medical instrument, the guide portion further configured to guide the navigation of the medical instrument to the fixation portion. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
