A method and apparatus for forming catheters and catheter curves using ferromagnetic materials exposed to an alternating magnetic field. Heat is generated in the exposed ferromagnetic material. The temperature of the ferromagnetic material is allowed to reach a desired temperature, preferably the Curie temperature of the ferromagnetic material containing portion. The heat generated is transferred to a catheter, wherein the catheter can be selectively formed or assembled and bonded at the desired elevated temperature.
