An apparatus (16) for deploying a radially self-expanding stent (18) includes proximal and distal sleeves (24, 30) respec- tively containing proximal and distal end regions (26, 38) of the stent in a reduced radius delivery configuration. The sleeves can abut one another and thus contain the entire length of the stent, or may be used in combination with an outer catheter (158) sur- rounding the sleeves and containing the medial region of the stent. In either event, once the stent and sleeves are positioned at the intended fixation site, the sleeves are moved axially with respect to one another to permit radial self-expansion of the stent initial- ly only over its medial region, while the sleeves continue to contain the axially outward regions of the stent. Eventually, upon suf- ficient movement of the sleeves axially relative to one another, the stent becomes totally free of the sleeves, resulting in radial ex- pansion over the entire stent length. The axial relative movement of the sleeves can be controlled by two or more catheters (20, 44) mounted movably with respect to one another, one catheter integral with each of the sleeves. Alternative arrangements for sepa- rating the sleeves include an externally threaded inner catheter (160), and a dilatation balloon (140) or membrane (206) expand- able to force the sleeves apart from one another.
