Abstract: A medical device may include an elongate delivery sheath and a valve replacement implant disposed within a lumen of the delivery sheath, the implant including an anchor member reversibly actuatable between a delivery configuration and a deployed configuration. The implant may include at least one locking element configured to lock the anchor member in the deployed configuration, and at least one actuator element configured to engage the at least one locking element and actuate the anchor member between the delivery configuration and the deployed configuration. The at least one actuator element may include an unlocking member configured to compress a first locking portion of the at least one locking element to unlock the anchor member from the deployed configuration.
