1. A bipolar dilation-and-cutting catheter assembly adapted for insertion into a body conduit of a patient, comprising:

  • an elongate tubular body having an axis and a distal end carrying a generally cylindrical radially dilatable member adapted to be positioned longitudinally in a body conduit and having properties for dilating generally radially of the tubular body;

    at least two wires carried by the tubular body exteriorly of the dilatable member, the wires disposed longitudinally of the tubular body and movable radially in a plane including the axis of the tubular body;

    means for dilating the dilatable member to exert dilation forces on the body conduit and to move the wires to a position adjacent to the tissue of the body conduit; and

    means for activating the wires to create an incision in the tissue.
