Systems, devices, and methods for controlling cooperative surgical instruments are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common body cavity of a patient from different approaches to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of surgical tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and operate in concert with one another to effect a desired surgical treatment.

A medical device for assessing and/or rehabilitating a human joint of an extremity includes a joint brace comprising a first support for coupling to an upper part of the extremity, a second support for coupling to a lower part of the extremity, and a rotatable joint connecting the first and second supports, and a mechanical device coupled to the first and second supports, the mechanical device configured for moving one or more of the first and second supports so as to rotate about the joint. In another alternative the medical device can include sensors located for making angle measurements between the first and second supports and for recording movement data and a computing device for receiving and storing the angle measurements and the movement data and for transmitting said data via a radio transmitter.

Intraoral electrical stimulation devices are disclosed. A representative device, which can be used to treat sleep apnea, includes an intraoral attachment body, a guide element carried by the attachment body and having a constrained guide path, and an electrode movably supported relative to the guide element and movable along the constrained guide path to a plurality of positions. A positioning member is coupleable to the electrode to move the electrode along the constrained guide path, and a signal generator is coupleable to the electrode to direct a stimulation signal to the electrode.

Arrangements described herein relate to systems, apparatuses, and methods for a headset system that includes a transducer configured to collect physiological data of a subject, a device housing configured to support the transducer, an insert portion disposed on the device housing, a support structure comprising a baseplate and a receiving portion, and a head cradle supported by the baseplate. The receiving portion extends in a direction that is oblique with respect to the baseplate. The insert portion is sized and shaped to engage the receiving portion to removably attach the device housing to the baseplate.

Some embodiments of the present disclosure are directed to ultraweak photon emission imaging systems and methods. In some embodiments, a method comprises acquiring an ultraweak photon emission image of a target area of a patient for detection of a pathological condition; wherein the target area comprises an area of interest and a portion surrounding the area of interest, wherein acquiring the image comprises: enhancing formation of reactive oxygen species and/or reactive nitrogen species in the target area, wherein enhancing formation of the reactive oxygen species and/or the reactive nitrogen species comprises applying low level light illumination to the target area from 1 second to 60 minutes so as to achieve a total power output from 1 mW to 10,000 W using an average power density from 0.1 W/cm.sup.2 to 1 W/cm.sup.2; and imaging the target area, wherein imaging the target area comprises a total exposure time from 1 second to 60 minutes.

An ear-worn device includes a speaker, an optical emitter, an optical detector, a processor, and a housing configured to be positioned within an ear of a subject, wherein the housing encloses the speaker, optical emitter, optical detector, and processor. The housing includes at least one window that exposes the optical emitter and optical detector to the ear of the subject, and the housing includes at least one aperture through which sound from the speaker can pass. Light transmissive material is located between the optical emitter and the at least one window and is configured to deliver light emitted from the optical emitter to an ear region of the subject at one or more predetermined locations. Light transmissive material is positioned between the optical detector and the at least one window and is configured to collect light external to the housing and deliver the collected light to the optical detector.

A charging station for providing power to a physiological monitoring device can include a charging bay and a tray. The charging bay can include a charging port configured to receive power from a power source. The tray can be positioned within and movably mounted relative to the charging bay. The tray can be further configured to secure the physiological monitoring device and move between a first position and a second position. In the first position, the tray can be spaced away from the charging port, and, in the second position, the tray can be positioned proximate the charging port, thereby allowing the physiological monitoring device to electrically connect to the charging port.

A back-mounted support device provides a stable platform for various monitoring and position support devices. The support device comprises a stiffening member configured for placement along a user's spine, the stiffening member extending from a top end to be positioned between the user's shoulder blades to a bottom end to be positioned along the spine and near a waistline of the user. A shoulder attachment system is coupled to the stiffening member to stabilize an upper portion of the stiffening member. A waist attachment system is coupled to the stiffening member to stabilize a lower portion of the stiffening member. The shoulder and waist attachment systems are configured to stabilize the stiffening member along the spine, while minimizing irritating body contact. Monitoring devices may be mounted anywhere on the support device for facilitating monitoring of body parameters.

Instruments and methods for wide-field polarized imaging of the skin to determine an outer lesion margin objectively in vivo to provide guidance to a surgeon. Quantitative characterization of collagen structures in the skin can be used to determine the outer lesion margin or monitor skin treatment.

An apparatus for evaluating motions of a joint is provided that is designed for determining stability of an anatomical joint. The apparatus includes a support frame, a fixation assembly for securing a first body segment of a joint, and a displacement assembly mounted to the support frame. The fixation assembly includes an axis of rotation moveable relative to the support frame. The displacement assembly includes a first frame pivotably mounted to the support frame and rotatably connected to a first end of the fixation assembly, and a second frame pivotably mounted to the support frame and rotatably connected to a second end of the fixation assembly.
