Patent ID: 7799065

Claim:
A delivery system for delivery of a medical device, the delivery system comprising: an inner member having a proximal end and a distal end, the inner member defining a longitudinal axis therebetween; a sheath disposed about the inner member, the sheath having a proximal end and a distal end, the sheath being movable between a first sheath position to a second sheath position; a handle coupled with the proximal end of the inner member; and an actuator on the handle including a slider configured for linear movement and having an elongate surface with a plurality of teeth therealong, the actuator coupled to a rack-and-pinion assembly; the rack-and-pinion assembly including: a pinion coupled with the sheath, the pinion configured for linear movement in the same direction as the slider and having a plurality of teeth along its length; and at least one rack gear being rotatable about a center axis, the at least one rack gear including: a circumferential surface, a first gear pitch operatively coupled with the pinion for linear movement of the pinion upon rotation of the at least one rack gear, and a second gear pitch vertically displaced on a height of the circumferential surface, the first gear pitch being different from the second gear pitch, wherein the plurality of teeth of the slider are operatively coupled with the second gear pitch of the at least one rack gear for rotation of the at least one rack gear and linear movement of the pinion and sheath along the longitudinal axis upon linear movement of the slider.
