An physiological measurement device provides a device body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

Embodiments herein relate to hearing device systems that can utilize proxy devices to convey emergency communications. In an embodiment, the system operates in a first communication mode and a second communication mode. The first communication mode can include the hearing device being paired to a wireless communication enabled device for conveying data to a non-local network as initiated by the hearing device. The second communication mode can include the hearing device accessory being paired to the wireless communication enabled device for conveying data to the non-local network as initiated by the hearing device. The system can enter the second communication mode when the hearing device cannot communicate with the wireless communication enabled device. The hearing device accessory uses a hardware address of the hearing device to communicate with the wireless communication enabled device as if it was paired thereto. Other embodiments are also included herein.

Disclosed biopsy markers are adapted to serve as localization markers during a surgical procedure. Adaptation includes incorporation of materials detectable under ultrasound during surgery, as well as features for co-registration with image guidance or other real-time imaging technologies during surgery. Such biopsy markers, when used as localization markers, improve patient comfort and reduce challenges in surgical coordination and surgery time. Additional disclosed biopsy markers are adapted to serve as monitoring and/or detection apparatuses. Localization of an implanted marker may be done with ultrasound technology. Ultrasound image data is analyzed to identify the implanted marker. A distance to the marker or a lesion may be determined and displayed. The determined distance may be a distance between the ultrasound probe and the marker or lesion, a distance between the marker or lesion and an incision instrument, and/or a distance between the ultrasound probe and the incision instrument.

Described herein are sensing cannula systems that include a surgical instrument, a detection unit, and a conductive pad having a reference electrode and configured to be placed on the patient at a location outside the patient's body. The surgical instrument can include a cannula (such as a fat grafting cannula) having an electrically conductive distal tip and electrical insulation covering the cannula proximally from the distal tip, wherein the distal tip comprises a first electrode. The detection unit can include electrical circuitry that is electrically coupled to the surgical instrument and the conductive pad and operable to measure an electrical impedance between the first electrode and the reference electrode to determine what type of tissue the distal tip is in.

The present invention relates to a visualization system disposed in a human body, including, a nanobot configured to be disposed within the human body, the nanobot having at least one embedded biosensor, the biosensor which operates in real-time to continuously obtain data from within the human body; a visualization device configured to be integrated and/or embedded within the nanobot to provide real-time visualization data in the human body; a transmitter/receiver disposed on the nanobot which transmits data from the nanobot to an external transmitter/receiver, the transmitted data including the data from the biosensor and the data from the visualization device; and a processor configured to receive the data from the external transmitter/receiver of the nanobot and analyze the visualization data to determine the anatomic localization of the nanobot at a specific anatomic position within the human body.

Automated assessment of neural response recordings involves storing a set of basis functions comprising at least one compound action potential basis function and at least one artefact basis function. Neural recordings of electrical activity in neural tissue are obtained by application of stimuli, using a single configuration of stimulation and recording. Each neural recording is decomposed by determining at least one parameter which estimates at least one of a compound action potential and an artefact. The at least one parameter is/are determined for each respective one of the plurality of neural recordings, to yield a plurality of values. A spread of the plurality of values is determined. An indication that the neural response recordings are of higher quality is output if the spread is small. An indication that the neural response recordings are of lower quality is output if the spread is large.

A neurostimulation system includes an electromyographic (EMG) electrode; a neural electrode implantable in a deep cerebellar nuclei of a subject; a data acquisition unit in communication with the EMG electrode for receiving and transmitting a EMG signal; and a processor in communication with the data acquisition unit, the processor generates a EMG pattern based on the EMG signal and outputs a stimulation signal to the neural electrode when the EMG pattern is indicative of an abnormal motor movement. A method of modulating an abnormal motor movement of a subject by using the neurostimulation system.

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.

Embodiments herein relate to ear-wearable devices configured to administer therapy to individuals who have suffered anoxic or hypoxic neurological injury and/or assess recovery from such injuries and related systems and methods. In an embodiment, an ear-wearable device is included having a control circuit, a microphone, a motion sensor, and a power supply circuit, wherein the ear-wearable device is configured to initiate a therapy for a wearer of the ear-wearable device and monitor signals from the microphone and/or the motion sensor to detect execution of the therapy. In an embodiment, the ear-wearable device is configured to evaluate signals from at least one of the microphone and the motion sensor to assess recovery from an anoxic or hypoxic neurological injury. Other embodiments are also included herein.

An exemplary monitoring system 1) monitors evoked responses that occur in response to acoustic stimulation during an insertion procedure in which a lead that is communicatively coupled to a cochlear implant is inserted into a cochlea of a patient, the monitoring comprising using an intracochlear electrode disposed on the lead to measure a first and a second evoked response at a first and a second insertion depth within the cochlea, the second insertion depth nearer to an apex of the cochlea than the first insertion depth, 2) determines that a change between the first evoked response measured at the first insertion depth and the second evoked response measured at the second insertion depth is greater than a predetermined threshold, and 3) determines, based on the determination that the change is greater than the predetermined threshold, that cochlear trauma has likely occurred at the second insertion depth.
