Checksite Medical, Inc., today, launched their new "CheckSite Medical System" today, designed to prevent surgeons from removing your left breast, when they were supposed to remove the right.

The system consists of a bracelet with a implanted RFID chip, a marker pen, and a series of sensors built into the walls and floors of operating rooms.

Under normal conditions, doctors are supposed to use a marker pen to mark on your body the place where surgery should occur. However in many cases, doctors fail to do this, resulting in 4,000 wrong-site surgeries each year.

The CheckSite System replaces the traditional wristband ID used on patients, with a special wristband ID containing an RFID chip. The walls and floors of a surgery room are embedded with sensors that detect this chip. When the patient is wheeled into the operating room, an alarm sounds.

The way to prevent this alarm from sounding, is to deactivate the chip by placing a special sticker on the wristband. This sticker comes from a one-time use marker pen. The doctor pulls the sticker off the pen, and fixes to the wristband, deactivating the chip. And with the pen in hand, it encourages the doctor to mark the area of surgery.
