1. A system, comprising:
an outer catheter, the outer catheter including:
a proximal end;
a distal end; and
a lumen extending therebetween;
a first marker and a second marker; and
an inner catheter slidably disposed within the lumen of the outer catheter;
a stent disposed over the inner catheter, the stent being configured to transition from a first configuration to a second configuration when not disposed within the lumen of the outer catheter, the stent comprising a proximal retention member when in the second configuration;
wherein the outer catheter is proximally retractable together with the inner catheter and the stent with respect to a reference position within a body lumen;
wherein the first marker is positioned with respect to the outer catheter, inner catheter, or both, and with respect to the stent, such that confirmation within the body lumen of the first marker proximal to the reference position denotes that the entire proximal retention member is deployable proximally relative to the reference position.
