WILL I BE ABLE TO TRAVEL?
Given the short duration of security screening, it is unlikely that your implanted heart device will be affected by metal detectors (walk-through archways and hand-held wands) or full body imaging scanners (also called millimeter wave scanners and 3D imaging scanners) such as those found in airports, courthouses, and jails.
To minimize the risk of temporary interference with your heart device while going through the security screening process, avoid touching metal surfaces around any screening equipment. Do not stop or linger in a walk-through archway; simply walk through the archway at a normal pace. If a hand-held wand is used, ask the security operator not to hold it over your implanted heart device and not to wave it back and forth over your device. You may also request a hand search as an alternative.
If you have concerns about these security screening methods, show your device ID card, request alternative screening, and then follow the instructions of the security personnel.
also it says you can go thought with an ICD

You may want to call or talk to Medtronic about just what they recommend to just double check on what they say, I do know a few people with inplant devices pacemaker, ICD, and a few others and none has too avoid meter doctors as being 6 feet from them will be hard if using one of the small boats to go to MK, or in other places.
