A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.

An early warning scoring system and method comprises a computing device, a plurality of sensors for acquiring physiological signals from a patient, wherein the sensors are functionally connected to the computing device, and at least one alarm adapted to output an alert upon an early warning score (EWS) exceeding a predetermined level. The computing device receives the physiological signals from the sensors, analyzes the physiological signals, and based on the analyzed signals, calculates the early warning score, and compares to the early warning score to predetermined limits and, if the score is outside the limits, triggers an alarm or actuates or modifies a treatment or medical intervention.

A nerve cuff for establishing a nerve block on a nerve can have a cuff body with a channel for receiving a nerve, a reservoir for holding a drug, and an elongate opening slit extending the length of the cuff body that can be opened to provide access to the channel and can be closed to enclose the cuff body around the nerve. The nerve cuff can also include an electrode for detecting and measuring electrical signals generated by the nerve. A controller can be used to control delivery of the drug based on the electrical signals generated by the nerve.

A pessary system for providing pelvic floor support for USL and other ligaments. The pessary has an elongated probe with independently inflatable balloons each located substantially the same distance from the insertion end of the probe and which inflate into separate radial sectors. The probe can be inserted into a vaginal cavity and the balloons inflated provide mechanical support to the USLs. Independent inflation of each balloon allows the mechanical USL support provided to be varied on left and right sides to compensate for differences in the degree of degradation and positioning of the USL ligaments on either side.

A aspiration system synchronous with heart-rate or other biometric signal used to determine cerebral blood pulsatility, that can include at least one sensor configured to be coupled to a patient. The at least one sensor can be electrically coupled to a heart-rate or other biometric signal monitor, which can be configured to detect a heartbeat or other biometric signal of the patient. A catheter with a distal end inserted into the patient can be coupled at the proximal end to the distal end of aspiration tubing. The proximal end of the aspiration tubing can be coupled to a collecting canister and to a vacuum generator, which is configured to pull a vacuum through the catheter to thereby aspirate a thrombus from the patient via the catheter. The vacuum generator can be configured to aspirate in response to the heart-rate or other biometric signal that can be used to determine cerebral blood pulsatility.

The nerve cuff can also include an electrode for detecting and measuring electrical signals generated by the nerve. A controller can be used to control delivery of the drug based on the electrical signals generated by the nerve.

Delivering vibratory therapy to a user may include using a system with a first transducer adapted to emit a first transcutaneous vibratory output; a second transducer adapted to emit a second transcutaneous vibratory output; and a processor in electronic communication with a user interface, the first transducer, and the second transducer, wherein the user interface accepts a user target state. The processor may be programmed to (i) generate a first transcutaneous vibratory output pattern comprising a first perceived pitch, a first perceived beat, and a first intensity; (ii) generate a second transcutaneous vibratory output pattern comprising a second perceived pitch, a second perceived beat, and a second intensity; (iii) cause the first transducer to emit a first transcutaneous vibratory output based on the first transcutaneous vibratory output pattern; and (iv) cause the second transducer to emit a second transcutaneous vibratory output based on the second transcutaneous vibratory output pattern.

A symptom intervention system monitors data representative of a user's movement, identifies an onset of a symptom of a physical condition, and applies an actuation to intervene with the identified onset. A machine-learned model is trained to identify an onset of a symptom based on the monitored data . The system may use the machine-learned model to determine whether to modify an upcoming administration of a chemical stimulus that is administered to the user to treat their physical condition. The system may determine a modification to a dose or a time associated with the upcoming administration of the stimulus and apply the stimulus to the user based on the determined modification. The system may use the machine-learned model to determine that the user is exhibiting a particular symptom of their physical condition. Depending on the symptom, the system may depolarize or hyperpolarize neurons of the user.

Systems, methods and devices for paired training include timing controls so that training and neural stimulation can be provided simultaneously. Paired trainings may include therapies, rehabilitation and performance enhancement training. Stimulations of nerves such as the vagus nerve that affect subcortical regions such as the nucleus basalis, locus coeruleus or amygdala induce plasticity in the brain, enhancing the effects of a variety of therapies, such as those used to treat tinnitus, stroke, traumatic brain injury and post-traumatic stress disorder.
