- a first elongate member having a proximal end with a longitudinal axis extending to a distal end;

a protective member in engagement with the handle and configured to extend from the handle around and beyond the deployment mechanism and over at least one portion of the elongate members wherein relative movement occurs, said protective member configured to inhibit impingement of external forces on the relative movement of the elongate members from the handle around and beyond the deployment mechanism and over at least one portion of the elongate members, wherein the protective member extends from the handle and over the deployment mechanism toward the distal end of the outer tubular member, such that a distal end of the protective member terminates proximal to the distal end of the outer tubular member;
wherein at least a portion of the second elongate member is disposed within the first elongate member, such that at least a portion of the second elongate member is longitudinally and axially displaceable relative to the first elongate member; and
wherein the first actuator has a first flange extending transverse to the longitudinal axis and greater than a diameter of the protective member, and the second actuator has a second flange extending transverse to the longitudinal axis and greater than the diameter of the protective member.

Abstract
A delivery device for positioning and deploying an implantable device within a lumen is provided. The delivery device includes inner and outer tubular members slidable to each other between at least a first hold position and a second release position, a handle and a deployment mechanism adapted for an operator to use a first hand for operating the delivery device and moving the tubular members between the first and second positions. The delivery device further includes a protective member adapted for insulating at least a portion of the outer tubular member from the tendency of the operator to use his or her second hand to grab the outer tubular member during operations or from other external forces.
