1. A delivery device for deployment of an implant comprising:

  • a handle;

    a catheter extending from a distal end of said handle, said catheter including a delivery catheter and a pusher catheter slidingly disposed within said delivery catheter;

    a drive mechanism attached to said pusher catheter and said delivery catheter and including a control knob and a threaded shaft such that rotation of said control knob results in axial movement of said threaded shaft, said axial movement of said threaded shaft effecting relative axial movement between said pusher catheter and said delivery catheter, wherein said delivery catheter is fixed to said distal end of said threaded shaft;

    a quick release mechanism associated with said control knob, said quick release mechanism disengaging said drive mechanism such that said threaded shaft may be moved axially without rotation, wherein said quick release mechanism comprises a button on said control knob, and wherein said threaded shaft includes interrupted helices that form a longitudinal slide over which said quick release mechanism rides when said button is pushed.
