An occlusive device, occlusive device delivery system, method of using, and method of delivering an occlusive device, and method of making an occlusive device to treat various intravascular conditions is described.

The invention relates to a method for producing a flat spiral spring, in particular a spring sheet for covering a cooling area of a piston of internal combustion engines, said spring sheet being formed at least as an annular disk-shaped segment (12), wherein a strip-shaped material (23) is fed to a bending device (27) that comprises at least one drum (29), said drum rotating about a rotational axis (31), and the strip-shaped material (23) is supplied in a tangential alignment to the lateral surface (36) of the drum (29) such that a lateral wall (20) which determines the thickness of the strip-shaped material (23) rests against at least some sections of a contact surface (37) on the lateral surface (36) of the drum (29). The contact surface (37) of the drum (29) has a radius which substantially corresponds to an internal radius of the strip-shaped material (23) to be bent into the segment (12), and at least one deflecting device (32) is aligned at a distance to the drum (29) such that the strip-shaped material (23) is guided in a forced manner between the drum (29) and the deflecting device (32), and the strip-shaped material (23) is bent so as to follow the drum (29) by means of the deflecting device.
