1. A delivery device for a stented heart valve comprising:

  • a handle;

    an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal terminal end of the inner catheter shaft, wherein a distal-most face of the bumper element defines a central passage and a complete, uninterrupted annular surface defined as an area between the central passage and a maximum outer diameter of the distal-most face of the bumper element, wherein the maximum outer diameter is a complete uninterrupted circle and further wherein the distal-most face is configured to abut the stented heart valve;

    an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, the outer catheter shaft including a generally cylindrical housing at a distal side that is structured to receive the bumper element therein; and

    a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft;

    wherein the retraction mechanism can move the outer catheter shaft into an extended position and a retracted positon;

    wherein, when the outer catheter shaft is in the retracted position, no part of the delivery device is more distal than the distal-most face.
