1. A method of deploying a stent, comprising:
- providing a delivery system with the stent loaded in a reduced diameter configuration between an inner catheter and an outer sheath, the stent including a covering positioned on a luminal wall surface thereof, the inner catheter including a radially outwardly extending protrusion that extends into the covering but does not intersect a plane along the stent luminal wall surface;
advancing the delivery system to a stenting site; and
withdrawing the outer sheath to deploy the stent at the stenting site.

11. A method of deploying a stent, comprising:
-
providing a delivery system with the stent loaded in a reduced diameter configuration between an inner catheter and an outer sheath, the stent being a covered stent having a matrix with surfaces defining luminal and abluminal envelopes spaced apart by a stent wall thickness, a covering material bonded to the matrix lying radially inside the luminal envelope, the inner catheter including a radially outwardly extending protrusion that extends into the covering but does not reach radially outwardly as far as the luminal envelope; advancing the delivery system to a stenting site; and withdrawing the outer sheath to deploy the stent at the stenting site. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
