| Summary: | A balloon catheter assembly (
10
) including a balloon section (
14
), a radiofluid port (
40
), and a magnetizing section. The magnetizing section generates a magnetic field that enhances the energy of the electrons (Beta particles) from radiofluid within the balloon section to increase the depth dose. The magnetizing section may comprise a solenoid arrangement (
70
) wherein wires (
72,74
) within catheter wall (
20
) having coils (
76
) surrounding the catheter within the balloon section (
14
) are connected to a controlled source (
86,88
) of milliamperage or microamperage, and generate a magnetic field within balloon section (
14
). Permanently magnetized distal end portions (
116,138
) of the catheter (
112
) or guide wire (
118
) or both, within balloon section (
114
), may be used to generate the magnetic field, or may be used in conjunction with a solenoid arrangement. |
