A stent delivery system, comprising:

• an inner member;
• a deployment sheath disposed about the inner member;
• a stent disposed between the inner member and the deployment sheath;
• a handle coupled to the inner member and to the deployment sheath, the handle comprising a rotatable actuation member having an outer rim and an inner portion inset relative to the outer rim, the actuation member being configured to shift the longitudinal position of the deployment sheath relative to the inner member;
• and
• a locking member comprising first and second inward-extending tabs, the locking member disposed over the outer rim of the rotatable actuation member such that the first and second inward-extending tabs each contact and apply an opposing inward force to the inner portion of the rotatable actuation member when the locking member is engaged with the actuation member to prevent unwanted actuation of the actuation member.
