Claim 13:
14. A delivery system comprising:
an expandable device;
a catheter having a first end and an opposite second end operable to support the expandable device;
a primary sheath operable to constrain the expandable device toward a collapsed configuration when in a delivery position and at least partially release the expandable device when in a deployment position; and
a handle coupled to the first end of the catheter and including a first actuator operable to control a first function of the handle, the first function including transitioning the primary sheath from the delivery position to the deployment position, the handle further including an arm operable to initiate a resulting function of the handle, the arm being spaced from the first actuator and configured to be engaged by the first actuator during operation of the first actuator such that there is an initial delay in the first actuator contacting the arm following actuation of the first actuator, wherein the first actuator includes a follower that is axially displaceable, the follower operable to engage the arm, wherein the first actuator is actuatable to cause an axial displacement of the primary sheath along the catheter from the delivery position;
a second actuator operable to perform a second function, wherein the arm extends from the second actuator and is axially displaceable, wherein the second actuator is initially hidden to prevent actuation of the second actuator prior to the primary sheath being displaced along the catheter from the delivery position, and wherein the second actuator is revealed as a result of the primary sheath being displaced along the catheter from the delivery position; and
a secondary sheath having a delivery position in which the secondary sheath limits expansion of the expandable device to an intermediate configuration larger than the collapsed configuration and smaller than a fully deployed configuration, and wherein the second function of the handle includes deployment of the secondary sheath to allow deployment of the expandable device from the intermediate configuration.
