Patent ID: 7780716

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 in contact with the proximal end of the inner member; and an actuator on the handle, the actuator including a slider coupled to a rack-and-pinion assembly 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 rack-and-pinion assembly including a rotatable pinion gear operatively coupled with the slider to move the pinion gear in a linear direction.
