A medical instrument is disclosed. The medical instrument includes a pair of spaced apart and electrically isolated elongated wire electrodes positioned adjacent one another on a working member. The wire electrodes are arranged for sensing electrical activity of biological tissues inside the body of the patient. The medical instrument also includes a pair of electrically isolated electrode wires that extend through the working member. Each of the electrode wires are electrically coupled to an associated wire electrode.

What is claimed is: 1. Apparatus for ablating targeted biological tissue, comprising: an elongated member including an elongated side for emitting a majority of tissue-ablative energy therethrough within an elongated pattern oriented in a selected direction toward targeted tissue; and a pair of elongated electrodes spaced apart near a distal end of the elongated side oriented in the selected direction for sensing electrical activity in targeted tissue. 2. Apparatus as in claim 1 including an additional pair of elongated electrodes disposed in the selected direction at a location proximal the elongated side for sensing electrical activity in targeted tissue. 3. A method for ablating biological tissue with an elongated member that selectively emits ablative energy, the method comprising: sensing electrical activity at laterally spaced apart locations in tissue targeted for ablation; orienting the elongated member with respect to a location on the tissue at which electrical activity is sensed; and activating the elongated member to emit ablative energy along an elongated pattern aligned normal to the lateral spacing and in a direction toward the targeted tissue adjacent the oriented elongated member. 4. The method according to claim 3 in which: sensing includes detecting electrical activity at laterally spaced apart locations proximal and distal the elongated pattern in tissue targeted for ablation. 5. Tissue ablation apparatus comprising: an elongated tubular member having a distal portion and a proximal portion and an elongated side wall of the tubular member between the distal and proximal portions for passing a majority of tissue-ablating energy therethrough toward targeted biological tissue along a radially angular direction about an elongated axis of the tubular member; and a pair of electrodes disposed along the side wall of the tubular member in the distal portion thereof spaced laterally apart relative to the elongated axis in substantial planar orientation that is substantially perpendicular to said direction. 6. Tissue ablation apparatus according to claim 5 including another pair of electrodes spaced laterally apart relative to the elongated axis at a proximal location along said side wall of the tubular member proximal said elongated side wall for sensing electrical activity at spaced locations in targeted tissue.
