Acoustic listening methods, devices, and systems herein relate to auscultation of a body. An auscultation device as disclosed herein can be operable to function within a cavity of the body, and can operate in conjunction with other auscultation devices, including with external auscultation devices. Individual devices and grouped devices can operate with the addition of a computing device. Systems and methods are disclosed with facilitate analysis and diagnoses of Eustachian function, swallow sounds, and bolus transit.

A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a replacement procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the replacement procedure. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.

Embodiments herein relate to ear-wearable stress and anxiety monitoring systems, devices and methods. Embodiments herein further relate to ear-wearable systems and devices that can detect and take actions to alleviate device wearer's stress and anxiety. In an embodiment an ear-wearable stress and/or anxiety monitoring system is included having a control circuit, a microphone, and a sensor package that can include a motion sensor. The ear-wearable system is configured to evaluate data from at least one of the microphone and the sensor package and classify a stress level of a device wearer using a machine learning classification model and periodically update the machine learning classification model based on indicators of stress experienced by the device wearer.

Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The methods and devices comprise storing, in memory in at least one of the IMD or the EI an advertising schedule defining a pattern for advertisement notices. The advertisement notices are distributed un-evenly and separated by unequal advertisement intervals. The method transmits, from a transmitter in at least one of the IMD or the EI the advertisement notices. The advertisement notices are distributed as defined by the advertising schedule. The method establishes a communication session between the IMD and the EI.

An example assembly for use with a vacuum system and an esophageal positioning device esophageal positioning device includes an introducer, in which the esophageal positioning device includes a handle, a first segment, a second segment and an articulation driving mechanism. The first segment being coupled to the handle. The second segment being pivotally connected to the first segment. The articulation driving mechanism being configured to pivot the second segment about the first segment upon articulation.

A system, method, scope device, and camera control module device for a stroboscopic laryngoscope, to enable scopes able to operate with a rolling shutter-type image sensor. With selected pulsing of a strobe light, subset image data from adjacent rolling-shutter frames is selected, gain compensated for missing light and combined into a new single video frame.

A method of facilitating therapeutic neuromodulation of a heart of a patient includes positioning an electrode in a pulmonary artery, positioning a sensor in vasculature, delivering via a stimulation system first and second electrical signals of a series of electrical signals to the electrode. The second electrical signal differs from the first electrical signal by a magnitude of a first parameter of a plurality of parameters. The method includes determining, via the sensor, sensor data indicative of one or more heart activity properties in response to the delivery of the series of electrical signals, and delivering a therapeutic neuromodulation signal to the pulmonary artery using selected electrical parameters. The selected electrical parameters include a selected magnitude of the first parameter. The selected magnitude of the first parameter is based at least partially on the sensor data. The therapeutic neuromodulation signal increases heart contractility.

A medical device system and method are disclosed for treating obstructive sleep apnea. The system includes a pulse generator and a medical electrical lead including multiple electrodes carried by a distal portion of an elongated lead body. The method includes advancing the distal portion within protrusor muscle tissue below the oral cavity and delivering electrical stimulation pulses via the electrodes to sustain a protruded state throughout a delivery time period to sustain a protruded state of a patient's tongue throughout the therapy delivery time period. The therapy delivery time period may span multiple respiration cycles.

Systems and methods for detecting cardiac conditions such as events indicative of worsening of heart failure (HF) are described. A system can receive a physiological signal from a patient, transform one or more first portions of the physiological signal into respective one or more baseline statistical values, transform one or more second portions of the physiological signal into one or more historical extreme values, and generate one or more reference values of a physiologic parameter using the baseline statistical values and the historical extreme values. The system can transform one or more third signal portions of the physiological signal into respective one or more short-term values, and produce a cardiac condition indicator using a combination of relative differences between the short-term values and the corresponding reference values. The system can output the cardiac condition indicator, or deliver therapy according to the cardiac condition indicator.
