1. A stent delivery system comprising:
a catheter body having an inner lumen, a proximal end, and a distal end;
a stent member having an inner lumen and a proximal end; and
a coupling member comprising:
a first connector with an inner lumen, disposed within the inner lumen of the catheter body and at the distal end of the catheter body;
a second connector with an inner lumen, disposed within the inner lumen of the stent member and at the proximal end of the stent member; and
a telescoping connector slidingly coupled to the first connector and the second connector,
wherein coupling of the first connector to the second connector concentrically aligns the catheter body and the stent member and releasably secures the stent member to the catheter body, and
wherein retraction of the telescoping connector from the second connector releases the stent member from the catheter body, and wherein prior to retraction, the telescoping connector is constrained within the inner lumen of the catheter body and within the inner lumen of the second connector.
