1. A system comprising:
an introducer sheath including a first hemostasis valve disposed therein; and
a catheter including
a handle;
a shaft distally extending from the handle;
a strain relief concentrically disposed over a portion of the shaft and distally extending from the handle;
a balloon disposed on a distal portion of the shaft;
a balloon-expandable prosthesis disposed over the balloon; and
a valve relief slidingly disposed over an outer surface of the shaft between a first position and a second position, wherein the valve relief includes a hub and a sheath, a proximal end of the valve relief sheath being coupled to the hub such that the valve relief sheath distally extends from the hub, the hub including a second hemostasis valve disposed therein that is configured to seal against the shaft when the shaft is disposed therethrough, the valve relief sheath in the first position being disposed directly over the balloon-expandable prosthesis to protect the balloon-expandable prosthesis during insertion into the introducer sheath, and the hub of the valve relief in the second position being disposed over a distal portion of the strain relief,
wherein the strain relief is configured to serve as a docking station for the valve relief when the valve relief is not disposed over the balloon-expandable prosthesis, and
wherein the valve relief sheath has a length that is configured to extend over an entire length of the balloon-expandable prosthesis when the balloon-expandable prosthesis is in a delivery configuration.
