Being the method of dealing with the organizational territory with the ultra wave, the method of including the fact that at the 2nd frequency which it forms at 1st frequency 1st stationary ultrasonic (USW) pattern in inside the said territory, simultaneously, 1st USW pattern the 2nd USW pattern which is superimposed spatially, in inside the said territory 1st frequency differs it forms.組織領域を超音波で処置する方法であって、第1の定常超音波(USW)パターンを該領域内において第1の周波数で生成し、同時に、第1のUSWパターンと空間的に重畳する第2のUSWパターンを、該領域内において第1の周波数とは異なる第2の周波数で生成することを含む方法。
