1. A medical device delivery system comprising:
a core member configured for advancement within a corporeal lumen; and
a coupling assembly positioned about the core member, the coupling assembly comprising:
an engagement member positioned about the core member, the engagement member including an outer portion having one or more projections separated by recesses along a circumferential direction, wherein the projections define an outer diameter of the engagement member and are configured to extend into pores of an overlying medical device; and
a disc-shaped resilient member positioned about the core member, wherein the resilient member is movable between a first state in which an outer diameter of the resilient member is smaller than the outer diameter of the engagement member and a second state in which the outer diameter of the resilient member is greater than the outer diameter of the engagement member, such that in the second state the resilient member physically blocks the projections of the engagement member from extending into the pores of the overlying medical device.
