1. A delivery device, comprising:
a housing having a housing proximal end, a housing distal end, and a housing body defining a housing lumen;
a cannula having a cannula proximal end, a cannula distal end, and a cannula body defining a cannula lumen, the cannula attached to the housing such that the housing lumen and the cannula lumen are in communication;
a pusher having a pusher proximal end, a pusher distal end slidably disposed within the housing lumen, and a pusher body that defines a pusher lumen, the pusher moveable between a pusher first configuration and a pusher second configuration; and
a catheter attached to the pusher and having at least a portion disposed within the cannula lumen, the catheter comprising an elongate member and a balloon, the elongate member having an elongate member proximal end, an elongate member distal end, and an elongate member body defining an inflation lumen in communication with the pusher lumen and an elongate member curve, the balloon disposed on the elongate member and having a wall defining a balloon chamber in communication with the inflation lumen, the balloon moveable between a first deflated configuration and a second inflated configuration as fluid is moved into and out of the balloon chamber, the elongate member adapted to move between a first substantially straight configuration in which the portion of the elongate member that defines the elongate member curve is substantially straight when disposed within the cannula lumen and a second curved configuration when the portion of the elongate member that defines the elongate member curve is free of the cannula lumen.
