Abstract: The invention is a crimping tool and methods of use that is suitable to connect electrical devices implanted in a living body. The invention enables manipulation of a narrow wire and a crimping component that are on the order of a millimeter in size. The crimper has a slideably attached connector holder that moves relative to the crimper to position an open end of the crimp connector between the crimp die and the crimp anvil, and a slideably attached wire holder that allows the wire holder to be moved relative to the crimper to position a portion of the wire within the open end of the crimp connector. Small components are positioned with precision using a combination of the user's senses, not necessarily including vision. The invention does not require stripping electrical insulation from the wires and is useful for interconnection of miniaturized non-medical electrical devices.
