Method and apparatus for r-f ablation

摘要

A deflectable catheter having a deflection wire which when moved longitudinally deflects the tip of the catheter into a generally planar first curve and a core wire which when torqued causes rotation of the first curve into a second plane. The catheter may also be provided with a second deflection wire arranged so that longitudinal movement thereof causes deflection of a portion of the catheter body proximal to the first curve formed by longitudinal movement of the first deflection wire. The catheter may be provided with a plurality of electrode coils for R-F ablation.
