Abstract

A device for providing access to a nodule, lesion, or pathological area in a lung or other body organ or lumen. The device includes a sheath portion having a proximal end and a distal end and a plurality of stabilization wires. The sheath portion includes a primary lumen that extends from the proximal end to the distal end and a plurality of secondary lumens that extend from the proximal end to the distal end. The stabilization wires are configured to be slidably received within the secondary lumens. The length of the stabilization wires is greater than the length of the secondary lumens.

First claim

1 - 11 . (canceled)

12 . A method comprising:
navigating a delivery device to a desired location with a lumen of a body; deploying a plurality of stabilization elements, from a distal end of the delivery device, into contact with tissue proximate a target nodule, wherein a first stabilization element of the plurality of stabilization elements is deployable independently from a second stabilization element of the plurality of stabilization elements; passing a treatment or diagnosis instrument through a central working channel of the delivery device while each of the first stabilization element and the second stabilization element are in contact with the tissue; and treating or collecting a sample from the target nodule.

13 . The method of claim 12 , further comprising:
returning the plurality of stabilization elements to the delivery device.

14 . The method of claim 12 , wherein the central working channel comprises a first interior dimension, wherein the deploying the stabilization elements is performed from a plurality of channels comprising a second interior dimension, wherein the first interior dimension is larger than the second interior dimension.

15 . The method of claim 12 , wherein the central working channel includes a central longitudinal axis, and
wherein deploying the stabilization elements occurs further from a center axis of the delivery device than the central longitudinal axis of the central working channel.

16 . The method of claim 12 , wherein deploying the stabilization elements comprises activating a stabilization elements control device configured to allow a user to control deployment of the stabilization elements.

17 . The method of claim 16 , wherein the stabilization elements control device comprises a handle portion configured to flexibly attach to proximal ends of the stabilization elements.

18 . The method of claim 17 , wherein the handle portion is configured to allow independent deployment of the stabilization elements.

19 . The method of claim 12 , wherein at least one of the stabilization elements has a keyed relationship with a respective one of a plurality of stabilization element channels.

20 . (canceled)

21 . The method of claim 17 , wherein the handle portion includes a normal vector and the stabilization elements control device includes a base section having a longitudinal axis, wherein when the handle portion is in a neutral position, the normal vector aligns with the longitudinal axis of the base section.

22 . The method of claim 21 , wherein when the handle portion is positioned relative to the base section with the normal vector having an angular divergence from the longitudinal axis of the base section, the center axis will be deflected by an amount comparable to the angular divergence of the normal vector of the handle portion.

22 . A device for providing access to a nodule, a lesion, or a pathological area in a lung or other body organ or lumen, the device comprising:
a sheath portion including:
a proximal end;
a distal end;
a primary lumen that extends from the proximal end to the distal end; and
one or more secondary lumens that extend from the proximal end to the distal end;
one or more stabilization elements, wherein the one or more of the stabilization elements are configured to deploy from respective ones of the one of the secondary lumens, wherein the one or more stabilization elements are extendable beyond the one or more secondary lumens; and a stabilization element control device configured to allow independent deployment of the stabilization elements.

23 . The device of claim 22 , wherein the primary lumen comprises a first diameter dimension, wherein the one or more secondary lumens comprises a second diameter dimension, wherein the first diameter dimension is larger than the second diameter dimension.

24 . The device of claim 22 , wherein the primary lumen and the secondary lumens include central longitudinal axes, wherein the central longitudinal axes of the one or more second lumens are located further from a central longitudinal axis of the sheath portion than the central longitudinal axis of the primary lumen.

25 . The device of claim 24 , wherein the central longitudinal axis of the primary lumen is collocated with the central longitudinal axis of the sheath portion.

26 . The device of claim 22 , wherein at least one of the stabilization elements is keyed to a predefined orientation within a respective one of the one or more second lumens.

27 . The device of claim 22 , wherein the stabilization elements are configured to deploy away from a center axis of the sheath portion.

28 . The device of claim 27 , wherein the distal end includes a distal face and the primary lumen and the one or more secondary lumens are exposed at the distal face

29 . A system comprising:
a medical instrument; and a device for providing access to a nodule, lesion, or pathological area in a lung or other body organ or lumen by the tissue interactive device, the device including:
a sheath portion including:
a proximal end;
a distal end;
a primary lumen that extends from the proximal end to the distal end; and
one or more secondary lumens that extend from the proximal end to the distal end;

one or mre stabilization elements that are deployable proximate to the distal end of the sheath, wherein the one or more of the stabilization elements include a first stabilization element, that is in mechanical communication with a first secondary lumen and a second stabilization element that is in mechanical communication with a second secondary lumen, wherein the first stabilization element is deployable independently from the second stabilization element; and
a stabilization element control device configured to allow independent deployment of the stabilization elements.

30 . The device of claim 29 , wherein the primary lumen comprises a first diameter dimension, wherein the one or more secondary lumens comprises a second diameter dimension, wherein the first diameter dimension is larger than the second diameter dimension;
wherein the primary lumen and the secondary lumens include central longitudinal axes, wherein the central longitudinal axes of the one or more second lumens are located further from a central longitudinal axis of the sheath portion than the central longitudinal axis of the primary lumen.

31 . The device of claim 29 , wherein the medical instrument includes a diagnosis instrument.
