ABSTRACT:
A RF ablation catheter for removing athero-stenotic lesions or modifying the tissue characteristics of the interior walls of selected blood vessels is described. The catheter has a distal tip member which is disposed in a working relation with the lesion to be removed during the initial placement of the catheter within the vascular system. Means are provided for increasing the cross-sectional profile of the tip member to thereby cause it to move into engagement with the lesion to be excised. The application of an RF voltage across a pair of bipolar electrodes is used to create an electric arc for effecting the cutting action, or alternatively, just sufficient RF energy to sear or otherwise alter the tissue surfaces engaged by the distal tip member.
