Delivery system for a medical device
First Claim
1. 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, the bumper including a sleeve member, the sleeve member having a length and a tubular wall;
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 and 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 configured to increase a deployment rate of movement for the sheath during at least a portion of movement of the actuator.

Abstract
The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.
