Abstract:
A joint comprising:a wound element extending to a wire end portion; and a mating component of a body implantable lead system, the mating component having an aperture to receive the end portion of the wound element, the mating component and the wire end portion of the wound element being integrally joined together by directing a laser beam substantially parallel to a longitudinal axis of the wire end portion to melt the wire end portion of the wound element and the mating component and the subsequent thermal fusion thereof; wherein the mating component includes a radially outwardly projecting ledge member with the aperture therethrough for receiving the wire end portion of the wound element; and wherein the mass of the radially outwardly projecting ledge member is substantially the same as the mass of the wire end portion to be melted such that thermal fusion requires equal energy distribution between the radially outwardly projecting ledge member and the wire end portion to be melted.
