A mechanical circulatory assist device is provided including a stent, a coiled wire wound around the stent, and a reciprocating valve including a housing, one or more leaflets coupled to the housing, and one or more permanent magnets coupled to the housing. The magnets are arranged to interact with a magnetic field generated by the coiled wire when current flows therethrough, so as to axially move the reciprocating valve with respect to the stent when the reciprocating valve is disposed within the stent. Upstream axial motion of the reciprocating valve causes the leaflets to be in an open state in which they allow blood flow through the reciprocating valve. Downstream axial motion of the reciprocating valve causes the leaflets to be in a closed state in which they inhibit blood flow through the reciprocating valve. Other embodiments are also described.

Systems and methods are provided to combine multiple stimulation modalities to significantly increase the effectiveness of non-invasive stimulation. Multiple sensor and stimulation devices and modalities can be combined into a single, compact unit that minimizes the need for additional sensors or stimulation devices. The system features several subunits, referred to as sensory and stimulation devices (SSD), that are integrated into a headphone setup. The system is controlled by a centralized controller that communicates with all of the SSDs and with an external computer system that delivers learning material synchronized with the delivery of stimulations and the collection of user responses based on physiological signals.

Systems and methods are provided for identifying a therapeutic VR activity or exercise for a subject/patient based on the subject's impairments, dynamically adjusting a VR activity for a patient, and identifying potential impairments based on a patient's performance in a VR activity. Patients may each have various physical, neurological, cognitive, and/or sensory impairments to be treated. Not all therapeutic activities may be appropriate for some patients and their impairments. A VR therapeutic activity platform may increase patient engagement and challenge patients at more appropriate times by better matching activities corresponding to a patient's impairments and dynamically adjusting each VR activity based on performance to offer a challenging and rewarding therapeutic experience.

Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

Aspects of the present disclosure provide a smart relaxation mask configured to output a stimulus and collect biometric information while the stimulus is output to determine if the subject is paying attention to the stimulus. If the subject is not focused on the stimulus, the mask adjusts at least one of an audio, visual, or haptic output. The stimulus is adjusted in an effort to shift the subject's attention to the stimulus and away from racing thoughts.

Blood glucose control systems are disclosed. A blood glucose control system can receive a glucose level signal from a glucose sensor operatively coupled to a subject. The system can decode encoded data of the glucose level signal to obtain the glucose level of the subject and the indication of the glucose trend. The system can automatically calculate the dose control signal using a control algorithm configured to calculate regular correction boluses of glucose control agent in response to at least the glucose level of the subject. The system can select a dose control signal encoding profile from a plurality of dose control signal encoding profiles and, based on the dose control signal encoding profile, encode the dose control signal such that the pump controller can read the dose control signal. The system can transmit an encoded dose control signal to the pump controller.

Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.

A respiratory assistance system can provide high flow therapy to patients. The respiratory assistance system can include a patient interface that can deliver a gas flow to a patient and a gas source that can drive the gas flow towards the patient interface at an operating flow rate. The system can include a controller for controlling the operating flow rate of the gas. The controller can apply multiple test flow rate values in a range as the operating flow rate. For each of the test flow rate values, the controller can measure a patient parameter. The controller can determine a new flow rate value based on the measured patient parameters. Patient parameters can include respiration rate, work of breathing, or any other parameters related to the respiratory circuit.
