ABSTRACT:
A multipurpose catheter apparatus for microwave aided balloon angioplasty includes a balloon capable of being filled with a lossy dielectric liquid, and bearing a metallization pattern. The catheter includes an electromagnetic transmission line. Radio frequency energy applied to the proximal end of the electromagnetic transmission line is radiated by an antenna within the balloon. The metallization pattern causes a portion of the energy applied to the proximal end of the transmission line to be reflected, which affects a characteristic such as impedance, return loss or time of reflection. A measurement apparatus measures the characteristic, and the distention of the balloon is determined from the measured characteristic. A guide filament may extend through the transmission line.
