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 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 gear to provide a first deployment rate for movement of the sheath and a second gear to provide a second deployment rate for the movement of the sheath.

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.
