A mass localization device (10) includes a catheter (12) and a needle (30). In one embodiment, the catheter includes inner (18) and outer (20) walls spaced from each other and creating a gap (22) between the walls extending along substantially the entire lenth of the catheter. The distal portion of the outer wall includes an inflatable balloon (28). In use, the balloon is positioned proximate the mass and inflated to make the mass palpable. An incision to the mass can be achieved by the shortest possible distance since the mass is made palpable. |
