1. An implantable stent comprising:
- a braided tubular member formed of a plurality of braided wires, the braided tubular member including a plurality of radially outward wire segments crossing over and positioned radially outward of a plurality of radially inward wire segments at a plurality of crossover points;
wherein the radially outward wire segments are coated with a coating and the radially inward wire segments are uncoated and devoid of the coating.

Abstract
An implantable stent may include a braided tubular member formed of braided wires and including radially outward wire segments crossing over and positioned radially outward of radially inward wire segments at a plurality of crossover points. Also, the radially outward wire segments may be coated with a coating and the radially inward wire segments may be uncoated and devoid of the coating.

10. An implantable stent comprising:
-
a tubular member formed of a plurality of braided wires forming a braid pattern including a plurality of crossover points; wherein first and second wire segments of the braided wires intersect at each crossover point such that the first wire segment crosses over and radially outward of the second wire segment while the second wire segment crosses under and radially inward of the first wire segment; a coating disposed only on the first wire segments which crosses over and is radially outward of the second wire segments; wherein the second wire segments crossing under and radially inward of the first wire segments are devoid of the coating. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of selectively coating portions of an expandable stent, comprising:
-
applying an axial force to a braided tubular member to change an axial length of the braided tubular member from a length of the braided tubular member in a nominally deployed state, wherein braided tubular member includes radially outward wire segments crossing over and located radially outward of radially inward wire segments of the braided tubular member at a plurality of crossover points; wherein applying the axial force changes an angle between the radially outward wire segments and the radially inward wire segments of the braided tubular member at the crossover points; thereafter, applying a coating to the radially outward wire segments while avoiding coating the radially inward wire segments. - View Dependent Claims (18, 19, 20)
