A system for creating separation between biological surfaces may comprise a hollow body configured for delivery of a fluid to a target location, a fluid supply in fluid-communication with the hollow body, a control element configured to control the delivery of a fluid through the hollow body, at least one first sensor configured to measure at least one parameter of the fluid flowing through the hollow body, at least one second sensor configured to measure at least one parameter of an environment of the hollow body, a feedback control module configured to receive information from one or more of the at least one first sensor or the at least one of the second sensor to control at least one operational function of the system.

A method and system for activity classification. A pressure sensor receives input data resulting from physical activity of a subject performing an activity. The input data includes pressure data from at least one pressure sensor, and may include other data acquired through other types of sensors. A deep learning neural network is applied to the input data for identifying the activity. The neural network is trained with reference to training data from a training database. The training data may include empirical data from a database of previous data of corresponding activities, synthesized data prepared from the empirical data or simulated data. The training data may include data from physical activity of the subject being monitored by the system. Different aspects of the neural network may be trained with reference to the training data, and some aspects may be locked or opened depending on the application and the circumstances.

A system and method for managing the care of a patient includes receiving (410) physiological signals of a patient; extracting (440) respiration information from the physiological signals; determining a vital sign of the patient by: using (450, 460) the respiration information to determine portions of the physiological signals, or of vital sign information extracted from the physiological signals, that correspond to the expiration phase of the respiratory cycle; determining (470) a vital sign of the patient using only the portions of the physiological signals, or of the vital signal information, that correspond to an expiration phase of the respiratory cycle; and displaying an indication of the determined vital sign at an output device.

A pelvic floor contraction detection system and method to evaluate pelvic floor muscle (PFM) exercise performed by a user are disclosed. The contraction detection system comprises a probe adapted to position within a pelvic cavity of the user, a data processing module, and a user interface. The probe comprises two or more sections. Each section is filled with a group of electronic sensors. The first and second sections are seated in contact with tissues of the pelvic cavity. The first and second groups of sensors are configured to detect pressure applied by the internal vaginal surface on the surface of the first and second sections of the probe respectively. The data processing module is in communication with the first and second groups of sensors and configured to calculate a number that is interpreted as the “quality of the contraction”. The data processing module determines the incorrect pelvic floor muscle contraction and notifies the user via a user interface.

A processing system obtains a deformation signal generated by a deformation sensor. The deformation signal is indicative of a deformation of an outer ear of a user of a hearing instrument. Additionally, the processing system obtains an EMG signal generated by an electrode in a concha of the user, wherein the electrode is configured to detect activity of an intrinsic auricular muscle of the user. Furthermore, the processing system generates information regarding an auditory attention state of the user based on the deformation signal and the EMG signal. The processing system controls, based on the information regarding the auditory attention state of the user, the parameter of the audio system.

A system for diagnosing and quantifying an organ prolapse includes a first manometry catheter configured for insertion within a first organ of the pelvic floor. The first manometry catheter includes an inflatable balloon configured to support a series of first sensors disposed along a length thereof and operably coupled to an image display for displaying a first image thereon relating to the first organ. One or more additional manometry catheters are configured for insertion within one or more respective additional organs. The additional manometry catheters include inflatable balloons configured to support corresponding additional sensors along a length thereof. The additional sensors are operably coupled to the image display for displaying one or more additional images thereon relating to the one or more additional organs. The first image and the one or more additional images being simultaneously displayed on the image display for diagnostic and quantification purposes.

Example inventions detect an occurrence of disturbance during a sleep period of a user. Examples receive data corresponding to a single parameter of the user during the sleep period, determine patterns in the data, and based on the patterns, determine a sleep disturbance severity index (“SDSI”) over the sleep period.

Systems and methods are provided for performing a medical procedure within a patient's body that involves a thoracic duct including an ostium communicating with the patient's venous system. A distal end of a catheter is introduced through the patient's venous system into a body lumen adjacent the ostium of the thoracic duct. An expandable member on the distal end of the tubular member may be expanded adjacent the ostium, e.g., within the body lumen or the thoracic duct itself, and used to isolate the thoracic duct from the body lumen, whereupon a medical procedure may be performed via the thoracic duct. For example, lymphatic fluid may be removed from the thoracic duct through a lumen of the tubular member and/or one or more agents may be introduced into the thoracic duct through the tubular member.

A low power force detection system includes variable capacitors, a drive sense module, and a processing module. A drive sense circuit of the drive sense module is operable to provide an analog and frequency domain signal to a variable capacitor. The drive sense circuit is further operable to detect a characteristic of the variable capacitor based on the analog and frequency domain signal and to generate a representative signal of the characteristic. The processing module is operable to generate a digital value based on the representative and to write the digital value to memory.

Implementations are directed to a pressure-sensing device including a pressure-sensitive sheet, one or more pressure-sensitive input regions disposed along the pressure-sensitive sheet including a first conductive thread including a first length in contact with the pressure-sensitive sheet, and a second conductive thread including a second length in contact with the pressure-sensitive sheet. At least a first portion of the first length of the first conductive thread passes through the pressure-sensitive sheet through a first hole in the pressure-sensitive sheet at a first location and a second portion of the second length of the second conductive thread passes through the pressure-sensitive sheet through a second hole in the pressure-sensitive sheet at a second location.
