1. A method for delivering a stent into Schlemm's canal, the method comprising:
a. detachably coupling a helical single elongated element to a pusher disposed inside a delivery device;
b. advancing the helical single elongated element into a channel of the Schlemm's canal;
c. adjusting the advancement of the helical single elongated element into the channel; and
d. uncoupling the helical single elongated element from the pusher, such that the helical single elongated element is inserted into the channel to radially expand or maintain patency of the channel;
e, wherein the delivery device is configured to block retraction of the helical single elongated element by bracing a proximal end of the helical single elongated element against a distal end of the delivery device such that the helical single elongated element does not retract while retracting the pusher.
