A marker for marking a site within the body of a mammalian patient is positioned within the tissue of a patient. The marker may be placed in the first instance by a needle or the like or placed where a tissue sample has been removed. The marker has a plurality of loops each at various angles to the other such that when positioned within the patient, one of the loops is positioned orthogonal to a magnetic field of a metal detector. Various shapes of markers may be used, including electron orbital shapes, chains of loops or barbells. Barbs or other anchoring elements may be used to stabilize the marker's position. Normal delivery techniques as needles, catheters or cannulas may readily position the marker within the patent. By having the marker so designed and positioned, at least one of the closed loops is detectable by a metal detection beam of a metal detection device.
