A stereo radiolocalization and targeting system includes a table assembly for supporting a patient, a stereo radiolocalization subsystem, a medical instrument support subsystem, and an ultrasound imaging subsystem. Optical isolators using the polarizing glass articles have reduced coupling and surface losses when compared with conventional optical isolators. An elongate connector spans the distance between the channels and has opposite side portions in respective engagement with the channels to connect the furniture articles together in a manner wherein the connector may be visually hidden in use. A diversity combiner optically coupled to each transponder determines respective signal strengths from each transponder in each transponder group. The methods and devices are particularly suited to the repair andor reconstruction of the spinal disc wall after surgical invasion or pathologic rupture, with reduced failure rate as compared to conventional surgical procedures.
