Vorrichtung zum Bestrahlen eines Gewebes mit einem magnetischen Feld

An apparatus for regulating in vivo tissue development which comprises: (a) means (42,44) for generating an applied magnetic flux parallel to a predetermined axis (50) and projecting through a predetermined space (68) containing in vivo the tissue (22,24); (b) means (46) for measuring magnetic flux density parallel to the predetermined axis in the predetermined space; (c) means associated with the flux generating means for fluctuating the applied magnetic flux; and (d) means for creating and maintaining a relationship between the rate of fluctuation of the magnetic flux and the intensity of the magnetic flux density, wherein predetermined relationship regulates the development of the tissue, and wherein the magnetic flux density has a non-zero net average value. i
