Rail tension extraction devices and methods of extracting target(s) inside a patient's body are disclosed. The device includes a base assembly having a handle and an elongate base. The device additionally includes at least one magnet configured to engage a metallic target, and a capture element received in the base assembly and disposed adjacent to the at least one magnet. The capture element is configured to at least partially surround the metallic target engaged by the at least one magnet. The device further includes an outer tube configured to move relative to the elongate base between a locking position in which a distal end of the outer tube is adjacent the capture element and the at least one magnet to secure the metallic target therebetween, and an unlocking position in which the distal end of the outer tube is spaced from the capture element and the at least one magnet.
