Pulmonary nodule access devices and methods of using the same
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.
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 sheath portion, the sheath portion having a proximal end and a distal end, the sheath portion comprising:
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;
a plurality of stabilization wires, wherein at least one of the stabilization wires is configured to be slidably received within one of the secondary lumens, wherein the length of the stabilization wires is greater than the length of the secondary lumens; and
a stabilization wire control device configured to:
flexibly attach to proximal ends of the stabilization wires; and
allow independent deployment of one or more of the stabilization wires.
2. The device of claim 1 , wherein the primary lumen comprises a first diameter dimension, wherein the at least one of the secondary lumen comprises a second diameter dimension, wherein the first diameter dimension is larger than the second diameter dimension.
3. The device of claim 1 , wherein the primary and secondary lumens include central longitudinal axes, wherein the central longitudinal axes of the second lumens are located further from a central longitudinal axis of the sheath portion than the central longitudinal axis of the primary lumen.
4. The device of claim 3 , wherein the central longitudinal axis of the primary lumen is collocated with the central longitudinal axis of the sheath portion.
5. The device of claim 1 , wherein at least one of the stabilization wires is keyed to a predefined orientation within a respective one of the second lumens.
6. The device of claim 1 , wherein the stabilization wires are configured to deflect away from a center axis of the sheath portion.
7. The device of claim 6 , wherein at least a portion of one or more of the stabilization wires comprises a shape memory material.
8. The device of claim 6 , wherein one or more of the stabilization wires comprises a piercing tip.
9. A device comprising:
a sheath portion, the sheath portion having a proximal end and a distal end, the sheath portion comprising:
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; and
a plurality of stabilization wires slidably received within one of the secondary lumens, the stabilization wires are configured to deflect away from a center axis of the sheath portion upon extending from the distal ends of the respective secondary lumens.
