METHODS AND APPARATUS FOR LUMINAL STENTING A stent delivery system (100), comprising: a microcatheter (110) having a distal end configured to be inserted into a blood vessel; a constraining member (320) extending within the microcatheter (110) and having a distal portion; a core member (160) extending within the microcatheter (110), the core member (160) having a distal segment; at least one sleeve (340) positioned about the core member (160) distal segment and rotatably coupled to the core member (160); and a stent (200) extending along the core member (160) distal segment, a proximal end of the stent (200) being engaged with the constraining member (320) distal portion and the sleeve (340) to restrict movement of the stent (200) relative to the constraining member (320) and the sleeve (340) while the core member (160) is rotatable relative to the stent (200), the constraining member (320), and the sleeve (340). |
