摘要： A mass localization device includes a catheter (12) and a needle (30). 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 length of the catheter. The distal portion (28) of the outer wall includes an inflatable balloon. A port extension member (38) is provided at the proximal end of the catheter for communicating a supply of air to the inflatable balloon via the gap between the inner and outer walls of the catheter. The needle is insertable through the catheter to extend beyond the distal end of the catheter. In use, the combination of the needle and catheter are inserted into body tissue. Under assistance of x-ray radiography, the device is moved toward a mass in the tissue. Once proximate the mass, an anesthetizing agent is introduced into the tissue through the needle. Subsequently, the balloon is inflated for contacting the mass, and thus making the mass palpable. The needle is withdrawn from the catheter, and the patient is prepared for a biopsy or other medical procedure. An incision to the mass can be achieved by the shortest possible distance since the mass is made palpable.
