Abstract: A method of navigating and positioning an endovascular device in a vasculature is disclosed. Initially, a system including an endovascular device and at least one transducer is inserted into the lumen of a patient. An acoustic signal is then transmitted within the lumen. A reflected signal is pre-processed to extract one or more acoustic features. The one or more acoustic features are processed using a computer readable set of rules to produce an output related to guidance of the instrument within a blood vessel or a position of the instrument within the blood vessel.

Abstract: In some examples, electrical stimulation is delivered to a patient such that selective termination of the stimulation causes a therapeutic effect in the patient after termination of the electrical stimulation to the patient. The electrical stimulation may be insufficient to produce a desired therapeutic effect in the patient during stimulation, but sufficient to induce a post-stimulation desired therapeutic effect following termination of the stimulation. In some examples, the electrical stimulation may be sub-threshold electrical stimulation. In some examples, the desired therapeutic effect may alleviate bladder dysfunction, bowel dysfunction, or other disorders. The stimulation may be selectively terminated in response to one or more therapy trigger events to induce the post-stimulation therapeutic effect.

Abstract: Disclosed is an exercise guidance system using an electromyography sensor, the system including: a control server receiving exercise information by working in conjunction with a monitoring module, in which an exercise guidance application is installed, over a wired/wireless communication network, the control server providing analysis information on user's exercise; and a signal processing module receiving detection signals from multiple electromyography sensors attached on a user body, calculating muscle activity by analyzing the detection signals, and providing a result of the calculation to the monitoring module. According to the embodiment, the cost burden of personal training is reduced, and the monotony of exercising along is reduced. Also, there is no limitation of place and time because exercise is possible anywhere. Also, the electromyography sensor works in conjunction with the smartphone to provide visualization of the user's exercise volume, the user's muscles, and the like, thereby facilitating efficient exercising.

Abstract: A knee orthosis provides varying levels of support to a patient during a stance phase and a swing phase of a gait cycle. The orthosis comprises an upper auxiliary support, a lower auxiliary support, an actuator, a sensor configured to detect a plurality of leg movements during the gait cycle and to output a plurality of detection signals corresponding to the detected leg movements, and a processor configured to determine whether the knee is in the stance phase or the swing phase of the gait cycle, to control the actuator to apply pressure on the lower auxiliary support when the knee is in the stance phase, and to release pressure when the knee is in the swing phase.

Abstract: A method is provided for processing a neural measurement obtained in the presence of noise, in order to detect whether a locally evoked neural response is present in the neural measurement. A first neural measurement is obtained from a first sense electrode. A second neural measurement is contemporaneously obtained from a second sense electrode spaced apart from the first electrode along a neural pathway of the neural response. A neural response decay is determined, being a measure of the decay in the neural response from the first sense electrode to the second sense electrode. A ratio of the neural response decay to an amplitude normalising term is calculated. From the ratio it is determined whether a locally evoked neural response is present in the neural measurement.

Abstract: A thermal control unit supplies temperature controlled fluid to one or more thermal pads used to control the temperature of a patient. The thermal control unit includes a fluid outlet, fluid inlet, heat exchanger, pump, and a controller. The controller receives first and second data from at least two different sources to determine if the patient is shivering or not. The two different sources may include a temperature sensor adapted to detect a temperature of the fluid, a temperature sensor adapted to detect a temperature of the patient, a tissue oxygenation sensor, a vibration/motion sensor, a thermal image sensor, an electromyograph, and/or other sensors. In some embodiments, the thermal control unit takes one or more automatic actions in response to detection of patient shivering.
