Ultrasonic treatment device and methods thereof

摘要

This invention discloses a method for treating tissue of a varicose vein, the method comprising applying ultrasonic vibrational energy targeting said varicose vein effective for stimulating and restoring tissue physiological functions of said vein. A catheter for treating tissue of a blood vessel comprises at least one ultrasound transducer element and at least a suction element configured and adapted for pulling the tissue toward the catheter radially, wherein the ultrasonic vibrational energy is provided by an ultrasound transducer element connected to an adjustable high frequency current source.
