A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is varied based on feedback gathered from physiological sensors that detect physiological characteristics of the patient during treatment.

An embodiment of a system for treating sleep apnea includes a collar, a pump, a motor, a sensor, and a controller. The collar is configured to maintain an airway of a subject open while the subject is sleeping by applying, to a throat of the subject, a negative pressure having a magnitude, and the pump is configured to generate the negative pressure. The motor is configured to drive the pump, and the sensor is configured to generate a sense signal that is related to a degree to which the airway is open. And the controller is configured to vary the magnitude of the negative pressure in response to the sense signal. For example, one or more of the pump, motor, sensor, and controller can be secured to the collar such that the system is self-contained, i.e., the entire sleep-apnea system can be worn by the subject.

Systems and methods are disclosed for assisting body motion by attaching a plurality of rods to a body; sensing movement parameters with sensors coupled to the rods; transmitting the movement parameters to a wearable device and receiving actuation commands from the wearable device; and based on the received commands, actuating the rods with one or more actuators.

Embodiments disclosed herein relate to a garment system including at least one muscle or at least one joint activity sensor, and at least one actuator that operates responsive to sensing feedback from the at least one muscle or the at least one joint activity sensor to cause a flexible compression garment to selectively compress against or selectively relieve compression against at least one body part of a subject. Embodiments disclosed herein also relate to methods of using such garment systems.

Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

A compression device for applying controllable compression to a portion of the anatomy of a user, includes a body, at least one memory wire embedded in the body and configured to contract in length upon application of a current so as to reduce an effective length of the body and apply a compressive force to the portion of the anatomy of the user, and a controller configured to selectively apply current to the memory wires to contract the memory wires and reduce the effective length of the body. The controller includes a circuit board supported by the body and a microcontroller mounted to the circuit board, the microcontroller programmed to actuate the memory wires according to a compression protocol stored in a memory associated with the microcontroller. Each memory wire has a first end fixedly connected to the circuit board and a second end fixed relative to the body.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises one or more shape-memory wires integrated into an article of clothing and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, a pre-tensioning apparatus in the form of a bungee cord associated with each shape memory wire, and a micro-processor based controller for selectively actuating the one or more shape memory wire to reduce the length of the shape memory wire to thereby apply pressure to the wearer's body.

A system and method of monitoring, controlling and/or detecting events during the removal of heat from subcutaneous lipid-rich tissue is described. In some examples, the system detects an increase in temperature at a treatment device in contact with the skin of a subject, determines that the increase in temperature is related to a treatment event, and performs an action based on the determination. In some examples, the system shuts off the treatment device, alerts an operator, or reduces the cooling in response to a determined treatment event.

The present disclosure relates to thermal contrast therapy systems, and automated thermal contrast therapy devices configured to interact with such systems and to perform customized thermal contrast therapy treatment sequences. Treatments may be prescribed by a treatment provider or selected by a user of a thermal contrast therapy device associated with such a system. In some embodiments, a thermal contrast therapy device may be configured to receive an indication from one or more temperature sensors and/or flow meters and to effect a desired measure of heat transfer during treatment, for example, by automatically adjusting the temperature and/or flow rate of the heat transfer fluid. In some embodiments, a thermal contrast therapy device may be configured to receive an indication of one or more physiological parameter values and to perform a customized thermal contrast therapy treatment sequence based, at least in part, on the one or more physiological parameter values.
