A portion of the received anatomical mapping data is selected for AR mapping to an anatomy of the patient. The selected anatomical mapping data is mapped to corresponding anatomical features. An AR environment is displayed to the user, wherein the AR environment includes the mapping of the selected anatomical mapping data to the corresponding anatomical features.

Abstract: Systems and methods for stimulation of neurological tissue generate stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide a lower average frequency.

Abstract: A human condition detection device comprises a depth image-taking module for taking a depth image of a target area. A millimeter-wave radar module detects breaths or heartbeats in the target area to provide a signal. A thermal image-taking module takes a thermal image of the target area. A processor module determines whether a person is in the target area based on the depth image. The processor module determines whether there is any breath or heartbeat based on the signal if a person is in the target area. The processor module determines whether there is any abnormal vital sign of the person in the target area based on the signal and the thermal image if there is a breath or heartbeat in the target area. The processor module actuates the warning module to provide a warning if there is an abnormal vital sign of the person in the target area.

The method involves independently and selectively activating the first and second electrodes to form an ablation zone, then repeating the ablation by delivering energy to a second set of electrodes, producing one or more overlapping ablation zone, and eliminating the need to reposition the ablation probes.

Abstract: The disclosure relates to a computer-implemented method for monitoring diaphragmatic response to phrenic nerve stimulation. The method comprises receiving in real-time a diaphragmatic CMAP signal. The method comprises computing a baseline value of a characteristic of the CMAP signal. The characteristic represents a diaphragmatic response intensity to a phrenic nerve stimulation. The method comprises determining a threshold value of the characteristic, representing a boundary of values of the characteristic indicative of upcoming diaphragmatic palsy. The determining of the threshold value includes shifting the baseline value. The method comprises receiving in real-time a ECG signal. The method comprises repeating in real-time: detecting a QRS complex in the ECG signal, monitoring the CMAP signal, computing a real-time value of the characteristic, comparing the real-time value to the threshold value, and outputting an alert when the threshold is passed.

Abstract: Techniques for calibrating a low frequency (LF) clock of an IMD are disclosed, wherein the IMD also includes a high frequency (HF) clock. This includes determining an average, or a surrogate thereof, of how many HF clock cycles of a HF clock signal (produced by the HF clock) occur per LF clock cycle of a predetermined number N of LF clock cycles of the LF clock signal (produced by the LF clock), wherein N is an integer that is at least 2. This also includes comparing the average or a surrogate thereof to a corresponding target value that the average or the surrogate thereof would be equal to if the frequency of the LF clock signal equaled a target frequency for the LF clock, wherein the corresponding target value need not be an integer. The LF clock is calibrated by adjusting the frequency thereof based on results of the comparing.

Abstract: A breath analysis system comprises a breath analysis device having a semiconductor sensor, such as a metal oxide semiconductor sensor, that needs to be heated or otherwise prepared before a breath test can be performed. To reduce or avoid a user-perceived delay (typically multiple minutes) associated with the sensor preparation operation, the system predictively initiates a sensor preparation operation based on a determination or prediction of whether the user is in an adequate state to perform a breath test. This prediction may be based on one or more factors, such as the current time, whether the breath analysis device is within wireless communication (e.g., Bluetooth) range of the user's smartphone, data reflective of the user's location and/or activity, etc.

Ultrasound measures are taken before administering a fluid bolus, including measurement of the left ventricular outflow tract velocity time integral (LVOT VTI), and venous measurements of the internal jugular vein. Data collected from such ultrasound scan is then used to predict the patient's cardiac volume response in the event that a fluid bolus is administered to that patient.

Abstract: An electrical interferential technique is used to determine operable treatment parameters which are then used to apply a treatment to a patient. A range of beat frequencies is applied to the patient and an indicator of autonomic nervous system activity is measured. When some degree of autonomic nervous system activity is detected, a subsequent trial is conducted using an overlaying range of frequencies, a narrower range or a single frequency, in an attempt to fine tune the reaction of the autonomic nervous system. The subsequent trial may use a different measure of activity of the autonomic nervous system. A garment having a series of electrode sites thereon may be used for a partially trained person to correctly apply electrodes to the patient's body. The treatments may be conducted while the patient is asleep.
