1. An implant configured to be deployed at a treatment location in a bronchial airway of a human subject, the implant comprising:
a proximal portion and a distal portion spaced apart from the proximal portion along a longitudinal axis of the implant, wherein the proximal portion is configured to be positioned in a proximal region of the bronchial airway and the distal portion is configured to be positioned in a distal region of the bronchial airway, the distal region comprising a greater generation than the proximal region; and
a single wire extending along a continuous helical wire path and having an untethered proximal terminus at an end of the proximal portion and an untethered distal terminus at an end of the distal portion,
wherein the wire path comprises a series of contiguous turns, each turn comprising first and second legs alternatingly disposed along the wire path with the first legs extending distally and the second legs pointing proximally, wherein at least one first leg and at least one second leg meet at an apex portion that points in a longitudinal direction along the longitudinal axis,
wherein the implant comprises a continuous opening extending between the turns of the wire path from the end of the proximal portion to the end of the distal portion, and
wherein the implant is configured to resiliently transition from a low-profile delivery state to an expanded unconstrained state, wherein the implant has a first average diameter in the low-profile delivery state and a second average diameter in the expanded unconstrained state, the second average diameter being at least three times larger than the first average diameter.
