Patent ID: 7794489

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 tip disposed at the distal end of the inner member; a bumper disposed on the inner member, the bumper having a proximal end and a distal end, a seat being defined between the tip and the distal end of the bumper; a sheath disposed about the inner member, the sheath having a proximal end and a distal end, the sheath being movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat; a handle connected to the proximal end of the inner member; and an actuator on the handle to move the sheath with respect to the inner member along the longitudinal axis from the first sheath position to the second sheath position, the actuator including a first adjust element operatively coupled to a first gear to provide a first deployment rate for movement of the sheath and a second adjust element operatively coupled to a second gear to provide a second deployment rate for the movement of the sheath, the first deployment rate being different than the second deployment rate wherein at least one of the adjust elements is moveable independently of the other adjust element.
