Abstract
A system for delivering a stent from a catheter sheath in a longitudinal direction comprising: a thumbwheel mounted on an axle, the axle being supported by opposite walls of a housing; a first pinion mounted on the axle; a second pinion mounted on the axle, whereby rotation of the thumbwheel causes rotation of the first pinion and rotation of the second pinion; a first rack, enageable with the first pinion at a first surface of the first pinion, the first rack being operably connected with a stent-engaging member; a second rack, engageable with the second pinion at a second surface of the second pinion, the second surface being disposed in a direction diametrically opposite the first surface, the second rack being operably connected with a sheath configured to confine the stent.
