PROBLEM TO BE SOLVED: To provide an ultrasonic treatment apparatus capable of treating arrhythmia with simple treatment.SOLUTION: An ultrasonic treatment apparatus includes: a long, thin probe which is inserted into a body, has a contact surface 2a that is brought into contact with tissue in the body and an ultrasonic generating device 24 that radiates ultrasonic waves into the tissue through the contact surface 2a and a signal detecting portion 22 which is provided at the contact surface 2a of the probe and detects an electrical signal from the tissue. The ultrasonic generating device 24 generates ultrasonic waves focused at a position F on the other side of the contact surface 2a from the ultrasonic generating device 24 with the contact surface 2a in between, the position being away from the contact surface 2a in a direction intersecting the contact surface 2a.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡便な処置で不整脈を治療する。【解決手段】体内に挿入されるとともに、体内において組織に接触させられる接触面2aと該接触面2aを介して組織に超音波を放射する超音波発生素子24とを有する細長いプローブと、該プローブの接触面2aに設けられ組織の電気信号を検出する信号検出部22とを備え、超音波発生素子24が、接触面2aを間に挟んで超音波発生素子24とは反対側に配され接触面2aから該接触面2aに交差する方向に離れた位置Fに集束する超音波を発生する超音波治療装置を提供する。【選択図】図2
