I agree. Earlier this year on my first two flights after having stents I triggered the body scan and was pulled aside for a pat down Australia & Canada). Told them the problem and offered to show them my international implant cards (which they didn't need to see), and as soon as I did that they sent me on my way. After that, I told them before the scan and had no problems in the USA & Canada.
