1. A stent device delivery system, comprisinga stent device pusher comprising protrusions with axially extending spaces therebetween;

  • a radially self-expandable stent device comprising a lumen extending longitudinally therethrough;

    an outer sheath, the stent device being constrained in a radially contracted state by the outer sheath so that the protrusions of the stent pusher engage an inner surface of the stent device at positions axially distributed along the stent device; and

    a tacky material axially distributed along the stent device and providing a tackiness between the stent device pusher and the inner surface of the stent device, wherein the tackiness and the engagement of the protrusions with the inner surface of the stent device serve to resist axial movement of the stent device relative to the stent device pusher as the outer sheath slides axially over the stent device and the tacky material is such that it allows the stent device to peel from the tacky material and expand to a radially expanded state as the outer sheath slides axially over the stent device to release the stent device.
