Abstract

A method of and apparatus for continuously forming wire (10) into a helical coil (56), spooling (90) that wire for convenient transportation and/or storage and then having that wire automatically snap back into the desired helical coil shape when the wire is unspooled. Through use of this method, large amounts of spooled wire with a 'memorized' helical coil shaped can be stored and then used as needed to make helical coil devices. In the preferred embodiment, Nitinol wire (10) is passed through a spring forming unit (20) to curve the wire, wrapped around a cylindrical mandrel (40), passed through a high temperature oven (50) and cooled so that the helical coil shape will be memorized.
