MAGNETICALLY SHIELDED ASSEMBLY

摘要

A shielded medical device implanted in a biological organism. The device has a magmetic shield, and the magnetic shield contains a layer of nanomagnetic material; such~layer has a morphological density of at least 98 percent. The nanomagnetic matelrial in such layer has a saturation magnetization of from about 1 to about 36,000 Gauss, a coercive force of from about 0.01 to about 5,000 Oersteds, a relative magnetic permeability of from about 1 to about 500,000, and an average particle size of less than about 100 nanometers.
