A surgical device for volumetric localization, biopsy and surgical procedures consists of a tubular shaft containing an array of filaments which are preformed and preloaded as springs. The filaments when deployed by extension from the tubular shaft, after insertion through or adjacent to a tumor or other tissue mass, form a predetermined, i.e., substantially closed loop, configuration outlining, encasing and excluding a known volume of tissue, i.e., tumor or other tissue mass, from the human body for the purpose of localization, biopsy or surgical removal. The filament array configuration, when outlining, enclosing and excluding the tumor or other tissue mass, limits tissue exposure to conventional and nonconventional forms of surgery to that within the encircling filaments.
