1. A deployment catheter for deploying a device into a lung, the deployment catheter comprising:
- a proximal end comprising a handle portion, the handle portion comprising a plunger, the plunger being surrounded by a movable handle, the movable handle configured to be slid axially in a direction along at least a portion of the length of the plunger, and wherein the plunger further comprises a locking lever capable of switching between locked and unlocked positions, the locking lever configured to prevent the movable handle from sliding in a proximal direction toward the plunger when in the locked position, but configured to permit the movable handle to slide in a proximal direction when in the unlocked position, and wherein the locking lever is further configured to reset to a locked position;
a catheter shaft portion, the catheter shaft portion comprising a catheter shaft and a stabilization wire inside the catheter shaft, wherein the catheter shaft is secured to the movable handle at the proximal end of the catheter shaft, and wherein the stabilization wire is secured to the plunger; and
a distal tip portion configured to receive a medical device in a cavity, wherein the distal tip portion is secured to the distal end of the hollow catheter shaft, and which further comprises a pusher plunger received within the cavity, the pusher plunger connected to the distal end of the stabilization wire.

Abstract
A deployment catheter is described herein that preferably is configured to deliver a medical device such as a valve to a location in a patient such as a patient'"'"'s airway. Preferably, such a deployment catheter is configured to be used in conjunction with a bronchoscope. In some embodiments, a locking lever is provided to reduce the likelihood of accidental deployment of the device, and which resets conveniently after use to as to permit multiple device deployments.

19. A method of deploying a medical device in a patient lung, the method comprising:
-
loading the medical device into a cavity disposed in the distal tip portion of a deployment catheter; introducing the deployment catheter into a bronchoscope; inserting the bronchoscope into a lung airway; navigating the bronchoscope to a portion of the lung airway to be treated; aligning the portion of the lung airway to be treated with at least one localization marker disposed on the distal tip portion of the deployment catheter; unlocking a locking lever on the deployment catheter; and deploying the medical device to the portion of the lung airway to be treated. - View Dependent Claims (20, 21, 22)
