1. A delivery device for positioning and deploying an implantable device within a lumen, said delivery device comprising:

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

    a second elongate member having a proximal end and a distal end, said first and second elongate members configured to cooperatively retain the implantable device near the distal ends and to move relative to each other to release the implantable device into the lumen, wherein the first elongate member includes an outer tubular member and the second elongate member includes an inner tubular member extending slidably within the outer tubular member, and wherein a space is defined between the inner tubular member and the outer tubular member near the distal ends to retain the implantable device;

    a handle coupled to the proximal end of at least one of the first and second elongate members;

    a deployment mechanism coupled to at least one of the inner and outer tubular members and operable to cause a relative motion of the first and second elongate members, wherein the deployment mechanism comprises a first slidable actuator positioned proximal to a second slidable actuator and operably connected thereto, such that slidably retracting the first slidable actuator moves the second slidable actuator and the outer tubular member proximally and longitudinally relative to the inner tubular member, and wherein one of the actuators is coupled to the proximal end of the outer tubular member; and

    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.
