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.
