Abstract: A catheter includes a braid assembly having a dual-laminate coating. The braid assembly includes a plurality of braid members interwoven to provide for interstices between the braid members, each braid member having an electrically conductive element, a flexible non-electrically-conductive polymer coating that insulates the electrically conductive element and a thermoplastic bonding adhesive coating. The braid assembly is formed between an inner polymer layer and an outer polymer layer. One or more of the braid members may be coupled to an energy delivery element.

Abstract: A robotic catheter control system includes a plurality of electric motors. Diagnostic logic automatically detects motor runaway fault conditions based on the current motor position, the target motor position and a predetermined tolerance parameter. Fault conditions include overshoot, movement in the a non-prescribed direction, exceeding a prescribed maximum motor speed and exceeding a prescribed maximum motor acceleration. The diagnostic logic terminates operating power to the electric motor when a fault condition is detected for any one of the motor. An error message is generated to notify the operator of the fault.

Abstract: Acoustic coupling systems and methods are disclosed as these can be used for assessment and ablation procedures. An exemplary acoustic assessment system for a catheter may comprise a flexible catheter shaft. At least one acoustic transducer is positioned in the flexible catheter shaft. The at least one acoustic transducer emits a generated acoustic signal for reflection by adjacent tissue. The at least one acoustic transducer receives a reflected acoustic signal from the adjacent tissue and generates electrical signals corresponding to one or more property of the tissue. An output device is electrically connected to the at least one acoustic transducer. The output device receives the electrical signals and generate output for a user for assessing the tissue.

Abstract: An efficient system for diagnosing arrhythmias and directing catheter therapies may allow for measuring, classifying, analyzing, and mapping spatial electrophysiological (EP) patterns within a body. The efficient system may further guide arrhythmia therapy and update maps as treatment is delivered. The efficient system may use a medical device having a high density of sensors with a known spatial configuration for collecting EP data and positioning data. Further, the efficient system may also use an electronic control system (ECU) for computing and providing the user with a variety of metrics, derivative metrics, high definition (HD) maps, HD composite maps, and general visual aids for association with a geometrical anatomical model shown on a display device.

Abstract: The present invention relates to open irrigated catheter ablation systems and methods used in connection with open irrigated catheter systems. The systems and related methods can control irrigation fluid flow to obtain temperature responses indicative of temperatures associated with an ablation procedure. Embodiments of the present invention provide irrigated catheter ablation systems having controlled irrigation fluid flow that can be directed at target areas where coagulation is more likely to occur to help minimize blood coagulation and associated problems. The irrigated fluid flow may be regulated in connection with an established or predetermined temperature threshold to improve or better optimize cooling and ablation properties of the system. In embodiments, irrigation flow may be either delayed or intermitted.

Abstract: A method of detecting dislodgement of a navigational reference for a localization system includes securing a reference catheter, including at least one reference localization element, at an initial reference location within a localization field. The positions of one or more of the reference localization elements are monitored for a perceived displacement that suggests that the reference catheter has become dislodged from the initial reference location (e.g., a displacement above a certain threshold, such as about 4 mm). The direction of this perceived displacement may then be further analyzed (e.g., compared to a predicted or most likely direction of displacement) to determine whether there has been an actual dislodgement of the reference catheter, and, if so, an appropriate signal (e.g., an audible or visual warning) may be generated. Upon dislodgement, guidance may be provided to aid the practitioner in restoring the reference catheter to its initial location.

Abstract: A system and method are provided for determining characteristics of a device electrode disposed on a medical device within a body. A plurality of measurement electrodes are coupled to an external surface of the body and establish transmission paths for current through the body. An electronic control unit (ECU) is configured to cause transmission of current between a pair of active electrodes selected from the measurement electrodes and thereby generate a voltage on the device electrode. The ECU receives impedance signals from a plurality of passive electrodes among the measurement electrodes other than the active electrodes. The ECU establishes a virtual reference electrode at a reference position within the body responsive to the impedance signals and computes a position of the device responsive to the voltage on the device electrode and the reference position of the reference electrode. The ECU may also compute impedances at the device and measurement electrodes.
