A device for delivery and attachment to the site of a nodule in the lung or other body organ or lumen to enable repeatable access to the site of the target nodule comprises a channel portion with a lumen through which medical devices and/or instruments can be navigated. The proximal end of the channel portion has an outwardly flared portion such as a plurality of outwardly projecting fingers forming a basket 723 or outwardly projecting strips (623, Figure 26) to facilitate insertion and docking of instruments into the proximal end of the guide channel. The distal end of the channel portion has extending directional members 721such as projections configured to deflect or bend the distal end of the channel away from a body wall and direct it toward a nodule or other site of interest. The projections of the directional member 721 can be oriented to vary the extent to which the distal end is deflected. |
