The invention provides a system that distributes along the length of a stent those forces exerted on the stent during release of the stent from a sheath. The system includes a catheter inner member, a stent, and a sheath. Multiple longitudinally spaced protrusions extend from the outer surface of a distal portion of the inner member. Complementary longitudinally spaced apertures are formed in the wall of the stent. The stent is mounted on the inner member with the inner member protrusions received within the stent apertures. The sheath encloses the stent and is movable with respect to the stent. The system is assembled by aligning the protrusions and apertures and radially compressing the stent about the inner member. The resulting interlocked protrusions and apertures allow the stent to be withdrawn from a radial compression device into the sheath by pulling on the inner member.
