A stent comprising a first member and further comprising at least one mechanism to reduce delamination of a substance disposed onto at least a portion of a surface of the stent, the at least one mechanism being either:

• a first mechanism, the first mechanism comprising a body, the body comprising a width, a first region and a second region, a first arm and a second arm, the first arm engaged to the body at the first region, the second arm engaged to the body at the second region, the first and second arms extending at oblique angles to the body, the first mechanism engaged to the first member;
• or
• a second mechanism, the second mechanism comprising a first transverse portion and an elongated portion, at least a portion of the first transverse portion being engaged to the first member, the first transverse portion being at an oblique angle to the first member, the elongated portion being parallel to the first member.
