Coaxial needles for repeated biopsy sampling.
A set of coaxial biopsy needles permits repeated tissue samples through an outer, larger needle that remains in place. The tract can be dilated from 23 to 16 gauge with the use of transfer rods, without loss of the initial position. The technique has been used successfully in six patients.
