Claim:
1. A drainage stent delivery system comprising: a drainage stent including a generally non-expandable tubular member having a proximal end, a distal end and a central longitudinal axis; an elongate shaft extending distally from a handle assembly to a location distal of the proximal end of the drainage stent, the elongate shaft including a portion configured to form an interference fit with the drainage stent; and an inner elongate member extending through the lumen of the elongate shaft, wherein the inner elongate member includes a projection that forms an interference fit with an inner surface of the proximal end of the drainage stent; wherein the portion of the elongate shaft configured to form an interference fit with the drainage stent is in contact with an exterior surface of the drainage stent; wherein the drainage stent is longitudinally moveable relative to the elongate shaft to effect disengagement of the drainage stent from the portion of the elongate shaft configured to form an interference fit with the drainage stent.
