    Abstract: In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.

    Abstract: A method and system for determining a target location for a medical device having complex geometry relative to an anatomical feature, and for navigating and positioning the medical device at the target location. The system may include a medical device including a treatment element having a centroid, one or more navigation electrodes, and a longitudinal axis and a navigation system in communication with the one or more navigation electrodes, the navigation system including a processing unit. The processing unit may be programmed to define a plane that approximates a surface of the anatomical feature, define a centroid of the anatomical feature, define a vector that is normal to the plane and extends away from the centroid of the anatomical feature, and determine a target location for the treatment element of the medical device based on the vector to assist the user in placing the device for treatment.

    Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

    Abstract: A method and system for automatic location of a target treatment structure, such as a pulmonary vein ostium, from an anatomical image. The method includes calculating a most likely path of blood flow through a pulmonary vein based on a cross-sectional area minimization technique and calculating pulmonary vein geometry as a function of length. For example, a pulmonary vein ostium may be located by analyzing a change in pulmonary vein dimensional size or other anatomical factors, such as absolute size. The method may also include determining tissue thickness at the pulmonary vein ostium or other treatment size for treatment dose optimization. The method may be an algorithm performed by a processing unit of a navigation system or other component of a medical system.

    Abstract: A fault-detection method, system, and device for a cryosurgical system that avoids a false-positive detection of a fault condition, such as fluid ingress within the system. The fault-detection mechanism may generally include a driver having an active mode and an inactive mode, the driver generating an output signal when the driver is in active mode, a detector, the detector capable of receiving the driver output signal, and a detector verification controller in communication with the driver and the detector, the detector verification controller changing the driver from the active mode to the inactive mode when the detector receives the driver output signal. The controller may determine a true fault condition if the controller determines there is a correlation between the signal received by the detector and the driver output signal. All other possible fault conditions may be ignored if the controller determines that the signals are not correlated.
