Abstract
The invention relates to a handle (10) for delivering a stent (2) by retracting a sheath (4) for protecting the stent (2), and is characterized in that it includes a tackle system (20) used to pull the protective sheath (4) over a predetermined retraction distance (D) to uncover the stent and enable the stent to be delivered and expanded. The tackle system greatly reduces the tractive force required to release the stent.
