Angioplastic microwave therapy systems designed to eliminate areas of narrowing in blood vessels by delivering microwave energy directly to treated tissue through an antenna. These systems consist of a microwave generator (2.45 GHz frequency is typical), a low-loss coaxial cable, and an antenna (e.g., whip); the coaxial cable with the antenna on its tip is introduced in the vessels through the lumen of a vascular catheter designed for balloon angioplasty.
