Abstract

Delivery systems for a medical device and related methods are provided. In one embodiment the delivery system includes a handle, a handle extension, and a sleeve. The handle extension extends from the handle and includes at least one channel defined therein along a longitudinal length of the handle extension. The handle extension also includes an abutment surface positioned in the at least one channel. The sleeve is disposed around the handle extension and is coupled to a catheter. The sleeve also includes a biased actuator configured to be moved between at least two actuator positions. The sleeve is moveable from a distal position to an intermediate position where it is stopped via the abutment surface to partially unsheathe a medical device from the catheter. The actuator can then be manually actuated to enable displacement of the sleeve to a proximal position to fully unsheathe the medical device from the catheter.
