Abstract: A catheter including a distal end assembly having an external surface coating. Where the distal end assembly includes electrodes or other electrical components, the coating is preferably electrically conductive. Such an electrically conductive coating is formed from a material comprising regenerated cellulose, although other materials such as a hydrogel or a plastic having an electrically conductive component are utilizable. Where the distal end assembly includes optical or ultrasonic components, the regenerated cellulose coating is suitable. The robustness of the surface coating permits the manufacture and utilization of electrode configurations that are formed on a non-conductive base member by processes such as pad printing, vapor deposition, ion beam assisted deposition, electroplating and other printed circuit manufacturing processes. Additionally, because the surface coating produces a smooth outer surface to the distal end assembly, lead wires and temperature sensing devices can be bonded to the exterior surface of electrodes and then coated to produce a smooth outer surface; thus providing a simple, inexpensive manufacturing method for the attachment of such components to the electrodes.

Abstract: This invention is devices and methods for ablating body tissue which use wire (44) wound about a support body (12) in adjacent windings to form one or more elongated electrodes. A connection couples the wire to a source of ablation energy for transmission by the elongated electrode to ablate tissue. The adjacent windings are spaced apart to impart enhanced flexibility to the elongated electrode during use.

Abstract: Systems and methods for locating an operative element within an interior body space use a locating probe, which includes at least one transmitting element to transmit an electric waveform output within at least a portion of the space. The systems and methods also use a sensing element, which is adapted to be carried by the operative element to sense a local electric waveform within the space. A processing element coupled to the sensing element generates a processed output that locates the sensing element relative to the locating probe based, at least in part, upon a differential comparison of the waveform output and the sensed local waveform.

Abstract: This invention is systems and methods that ablate body tissue using an electrode (16) for contacting tissue at a tissue electrode interface to transmit ablation energy at a determinable power level. The systems and methods include an element (50) to remove heat from the electrode (16) at a determinable rate. The systems and methods employ a processing element (98) to derive a prediction of the maximum tissue temperature condition occurring beneath the tissue electrode interface. The processing element (98) controls the power level of ablation energy transmitted by the electrode (16), or the rate at which the electrode (16) is cooled, or both, based, at least in part, upon the maximum tissue temperature prediction.

Abstract: Analog or digital systems (10) and methods generate a composite signal derived from a biological event in a time sequential fashion. A first set of signals derived from a biological event using a first group of sensors (20) during a first time interval is input. A second set of signals derived from the biological event during a second time interval sequentially after the first time interval using a second group of sensors (36) is input. The second group of sensors has at least one common sensor that is part of the first group and other sensors that are not part of the first group. The first and second sets of signals are time aligned using signals sensed by the at least one common sensor, thereby generating the composite signal. The time alignment is done by shifting the first and second sets of signals either with or without computing a time difference between them.

Abstract: An electrode support structure has a guide body (12) having a distal end and a stylet (80) having a bendable portion extending along an axis outside the distal end of the guide body (12). The structure also includes at least one flexible spline leg (22) having a body and a far end extending beyond the distal end of the guide body (12) and attached to the bendable portion of the stylet (80). The spline leg (22) is normally flexed between the distal guide body end and the bendable stylet portion in a first direction that extends along and radially outward of the axis of the stylet (80). At least one electrode element (28) is on the flexible spline leg (22). The bendable stylet portion (80) applies tension to flex the spline leg (22) in a second direction.

Abstract: Systems and methods use an array (20) of multiple electrodes (24) supported for operative association with a region of heart tissue, in tandem with a roving second electrode (36) supported for movement relative to the multiple electrodes for operative association with selected different regions of endocardial tissue within the heart. An analog or digital processing element (32) conditions one of the multiple electrodes and the roving electrode to emit a pacing signal while the other one of the multiple electrodes and the roving electrode records paced electro-grams occurring as a result of the pacing signal. A template of cardiac event of known diagnosis sensed using the array of multiple electrodes is input. A sample of a cardiac event acquired by pacing from at least one roving electrode and sensed with the array of multiple electrodes is input. The processing element and method electronically compare the sample to a template and generate an output.
