    Abstract: This invention is a catheter assembly (10) which has a distal end adapted for insertion into a living body, and a proximal end adapted to remain external to said body, or a cable for use in such an assembly that includes a cylindrical surface on which is inscribed a plurality of markings (16). Each of the markings indicates one of the specific locations within the living body at which the distal end may be placed during insertion. The markings are positioned at spaced intervals around the circumference of the cylindrical surface. A sleeve (18) is rotatably and/or axially movable around the cylindrical surface, the sleeve being provided with at least one window (20) adapted to be moved into alignment with a selected one of the markings.

    Abstract: This invention is systems and methods to examine heart tissue morphology using three or more spaced apart electrodes (38), at least two of which are located within the heart in contact with endocardial tissue. The systems and methods transmit electrical currents (64) through a region of heart tissue lying between selected pairs of the electrodes, at least one of the electrodes in each pair being located within the heart. The systems and methods derive the electrical characteristic of tissue lying between the electrode pairs based, at least in part, upon sensing tissue impedances. The systems and methods (206) also sense the timing of local depolarization events in the tissue in which impedance is sensed, and derive therefrom the propagation velocities of the sensed depolarization events.

    Abstract: A multiple electrode array (18) senses electrical events in heart tissue at different orientations in a localized region. First, second, and third electrode elements (60, 62, 64) are spaced apart along different axes. The electrodes (60, 62, 64) are electrically isolated from each other. The spaced apart and electrically isolated electrodes (60, 62, 64) sense multiple bipolar signals measured along the different axes. The electrode array (18) can, without changing position, continuously record multiple electrical events at different relative orientations within a localized area. The spacing and orientation of electrodes on the array (18) permit the physician to detect a small volume signal (like one associated with an accessory pathway), and to differentiate it from nearby large volume signals (like those associated with atrial and ventricular potentials).

    Abstract: A system and method for cardiac diagnosis and treatment inserts the distal end of a catheter (18) into a heart chamber. The distal end of the catheter (18) supports at least one electrode (22). The catheter (18) has a fluid flow conduit (62) extending through it. The conduit (62) has a valve (156) that prevents fluid flow from the heart chamber into the conduit (62) in response to in vivo pressure generated during heart systole and diastole. The valve (156) permits fluid flow from the conduit (62) into the heart at a pressure above the in vivo pressure. In use, the catheter (18) locates the electrode (22) in contact with a portion of the endocardium, and fluid is conducted from an external source through the conduit (62) at a pressure above the in vivo pressure to flush the area surrounding the electrode (22).

    Abstract: A combination catheter for both detecting monophasic action potentials and ablating surface tissue in an in vivo heart of a patient is provided. The apparatus includes a catheter probe having a terminal tip portion (10) and an electrode (20) carried on the tip such that a portion of the tip electrode (20) is exposed to ambient. A reference electrode (50) is spaced along the tip from the first electrode for supplying a reference potential signal. An ablating electrode (30) is located adjacent to but electrically insulated from both the tip (20) and reference (50) electrodes for providing electromagnetic energy to the tip. The electrodes are electrically connected to the proximal end of the catheter through individual conductors or wires (22, 32 and 50) that run through an insulated cable. An electronic filter is provided to permit the recording of MAPs during ablation without radiofrequency interference. The catheter may also include standard mapping and/or pacing electrodes (80) and (75) respectively. The catheter may further include a steering mechanism for positioning the catheter at various treatment sites in the heart, and a structure for holding the tip electrode in substantially perpendicular contact with heart tissue with a positive pressure, and for spacing the reference electrode from the heart tissue.
