Claim:
1. A pulmonary stent delivery system comprising: a first conduit, wherein at least a portion of a bronchoscope is positionable in the first conduit during use of the stent delivery system, and wherein the first conduit has a diameter of between 3 mm and 20 mm and is sized to allow a bronchoscope to move distally and proximally through the first conduit; a second conduit, wherein at least a portion of the first conduit is positionable in the second conduit, wherein the second conduit is configured to contain at least a portion of a pulmonary stent, wherein the stent comprises a distal portion terminating at a distal end and a proximal portion terminating at a proximal end, wherein the second conduit is movably positionable with respect to the first conduit, and wherein a distal end of the second conduit is movable in a direction toward a proximal end of the first conduit to expose at least a portion of the distal end of the stent during use; a stop coupled to, and protruding outwardly from, the outer surface of the first conduit and positioned approximate to the proximal end of the stent when the stent is positioned between the first and second conduits, wherein the stop is configured to abut against the proximal end of the stent to inhibit movement of the stent in a proximal direction relative to the first conduit; a bronchoscope that is positioned within the first conduit such that a distal end of the bronchoscope is extendable adjacent to a distal end of the first conduit, the second conduit or the stent; a first grip coupled to the first conduit, the first grip including a user-engagement portion extending radially away from a longitudinal axis of the first conduit; and a second grip coupled to the second conduit, the second grip including a user engagement portion that comprises a first finger grip that is configured to receive a user's index finger and a second finger grip that is configured to receive a user's middle finger, wherein the first finger grip extends radially away from a longitudinal axis of the second conduit in a first direction and the second finger grip extends away from the longitudinal axis of the second conduit in a second direction that is opposite of the first direction, wherein the first and second grips are configured to facilitate one-handed retraction of the second conduit to deploy the stent as the user retracts the second grip proximally toward the first grip; wherein the first conduit and the second conduit are sized to permit positioning of the stent between an outer surface of the first conduit and an inner surface of the second conduit, thereby allowing extension of the bronchoscope through the first conduit and the stent.
