Catheter (10) of ultrasound comprising: a body (12) of flexible elongate catheter having a proximal end, a distal end and at least unaluz (18) extending longitudinally therethrough an element (30) ultrasound transmission extending longitudinally through the lumen (18) of the body (12) of catheter, the element (30) ultrasound transmission a distal end queestá located at the distal end of the body (12) catheter, and a proximal end means for deflecting the distal end of the catheter body, wherein the diverter means comprise a cable (88) of deflection extending through laluz (18) of the catheter (10), the catheter (10) further comprising a connector (200) acoustic located at the proximal end delelemento (30) ultrasound transmission to connect the element (30) transmission ultrasonidosa a device (22) generating separate ultrasound and comprising a section (226, 226b) proximal to connection to a device (22) generating separate ultrasound, anda proximal housing (302, 302b, 302c) that is coupled to the proximal end of the body (22) decatéter, wherein the cable (88) of deviation has a distal end connected to the distal end of the body (12) proximal catheter yun end extending outside the body (12) of the catheter, characterized porqueel wire proximal end (88) deflecting a shooter is connected (90) elongation that estáprevisto at the proximal end of the cable (88) biasing yen which when pulling the handle (90), the cable (88) deflection elongates, thus causing elextremo distal catheter (10) deviates, and wherein when the pulling movement on eltirador (90) is released, the cable (88) deflection relaxes and assumes a straight orientation, the connector (200) acoustic comprises a portion (218, 218b) front having a hole (220, 220b) quealoja the proximal end of the element (30) of ultrasound transmission, the proximal housing has a hole (322) distal extending element (30) transmission deultrasonidos through the housing (302, 302b, 302c ) proximal, wherein the catheter (10) comprise
