1. A stent system, the system comprising:
a connector having a connector lumen;
an elongated outer shaft fixedly coupled to an outer shaft hub, the outer shaft hub being fixedly coupled to the connector, the outer shaft having an outer shaft lumen;
an elongated pusher shaft slidably disposed within the outer shaft lumen and the connector lumen and fixedly coupled to a pusher shaft hub, the pusher shaft having a first pusher shaft lumen and a second pusher shaft lumen, each of the first pusher shaft lumen and the second pusher shaft lumen extending from a proximalmost end of the pusher shaft to a distalmost end of the pusher shaft;
an elongated inner shaft slidably disposed within the first pusher shaft lumen and having an inner lumen;
a stabilizing wire slidably disposed within the second pusher shaft lumen; and
a stent comprising barbs, wherein the stabilizing wire is fixedly coupled by a weld or a clamp to a proximal end of the stent such that the stabilizing wire and the stent are configured remain coupled together as the stabilizing wire slides with respect to the elongated outer shaft and the stent self-expands to a deployed state with the barbs extending radially outwardly to penetrate a portion of a body lumen for a temporary period upon delivery to a target location within a human patient, the elongated inner shaft extending through a lumen of the stent.
