    摘要: A stent delivery system includes a handle having a housing and a spool. A pushrod has a proximal end connected to the housing of the handle. A stent is located near a distal end of the pushrod, wherein the handle has a linear length less than a linear length of the stent. A sheath constrains the stent at a distal end of the sheath. A retraction wire is connected to a proximal end of the sheath and to the spool. Retraction of the sheath is accomplished by winding (coiling) the retraction wire around the spool. Accordingly, the handle can be much shorter than the stent.
