Abstract
A prosthetic delivery system may include a plurality of concentric shafts and an actuator mechanism for actuating one or more of the concentric shafts. A stop mechanism may be coupled to the actuator mechanism. The stop mechanism prevents advancement or retraction of at least some of the shafts beyond a predetermined position unless the stop mechanism is released. A second stop mechanism may be included in the system for controlling another of the shafts. A plurality of filaments may be coupled to a prosthesis carried by the delivery system and actuation of the filaments may be used to control deployment or retrieval of the prosthesis.
