Abstract
An improved catheter system having ultrasound locating capabilities comprising a locator catheter and an ultrasound receiver catheter resulting in an effective electrophysiology procedure without undesired side effects of using a conventional x-ray imaging system. Said catheter system comprising a locator catheter consisted of a catheter shaft having a distal tip section, a distal end, a proximal end and at least one lumen extending therebetween, wherein at least one electrode is secured at said distal tip section; a handle attached to the proximal end of said catheter shaft; an ultrasound crystal secured on the catheter shaft proximal to the distal end; a connector secured to the proximal end of said handle; and a reference catheter comprising three or more ultrasound crystal beacons which have pre-determined locations with reference to an external locating calibration system, wherein said ultrasound beacons can emit and receive ultrasound signals, and the crystals used in ultrasound imaging means can be shaped as a cylinder, a donut, or a ring shape.
