摘要：
A stent deployment device (10) includes a catheter (12), a stent (14) positioned on the catheter (12), and a sleeve (16) carried on the catheter (12). The sleeve (16) has a portion (18) extending fully over and containing the stent (14). The stent deployment device (10) also includes a mechanism (20) for splitting at least the portion (18) of the sleeve (16) extending over the stent (14) and, preferably, for splitting the entire sleeve (16). Splitting of the sleeve portion (18) permits expansion of the stent (14). The mechanism (20) can include an inflatable, nondistending balloon (22) carried on the catheter (12), the stent (14) and the sleeve portion (18) being positioned over the balloon (22). The stent (14) can be self-expanding or can be expanded by the balloon (22) itself. It is preferred that at least the portion (18) of the sleeve (16) extending over the stent (14) includes a longitudinally extending structure (46) for ensuring that the sleeve portion (18) will in fact split upon operation of the mechanism (20).
