PROBLEM TO BE SOLVED: To provide a method and an apparatus which treat chronic total occlusion (CTOs), especially the chronic total occlusion hard to be treated.SOLUTION: CTO recanalization is carried out by constituting a guide wire 100a and a guide wire 100b to be functioned as an electrode or a lead wire, passing an antegrade guide wire 100a through a proximal end of an occlusion and passing a retrograde guide wire 100b through a distal end of the occlusion, and performing high-frequency wave cauterization on the occlusion between both of the guide wires with output from an RF generator 10.COPYRIGHT: (C)2015,JPO&INPIT【課題】慢性完全閉塞(CTOs)、特に治療が困難な慢性完全閉塞を治療する方法および装置を提供する。【解決手段】CTO再疎通は、ガイドワイヤ100aおよびガイドワイヤ100bを電極または導線となるように構成し、順行性ガイドワイヤ100aを閉塞の近位端を通して進め、逆行性ガイドワイヤ100bを閉塞の遠位端を通して進め、RF発生器10からの出力を用いて両ガイドワイヤ間の閉塞に対する高周波焼灼によって行う。【選択図】図1
