Claim 0:
1. A delivery system for endoluminal delivery of a device, the delivery system comprising:
a catheter having a proximal end and an opposite distal end operable to support the device;
a handle including a first actuator including a follower that is axially displaceable, the first actuator being operable to control a first function of the handle, the handle including an arm operable to initiate a resulting function of the handle, the arm being spaced from the follower and configured to be engaged by the follower during operation of the first actuator such that there is an initial delay in the follower contacting the arm following actuation of the first actuator, wherein the handle further includes a second actuator, wherein the resulting function of the handle includes revealing the second actuator from a hidden configuration to a usable configuration, wherein the second actuator is operable to control a second function of the handle:
a primary sheath having a delivery position, wherein the primary sheath constrains the device toward a collapsed configuration suitable for endoluminal delivery when in the delivery position;
wherein the first actuator is actuatable to cause an axial displacement of the primary sheath along the catheter from the delivery position, 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 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 device from the intermediate configuration.
