A novel medical imaging system that is based on radio-wave signals at microwave frequencies and has unique properties. The system can be used for various diagnostic applications such as breast cancer detection, brain stroke detection, and assessment of internal bleeding (trauma emergencies).

A system and method for monitoring body chemistry of a user, the system comprising: a housing supporting: a microsensor comprising a first and second working electrode, a reference electrode, and a counter electrode, and configured to access interstitial fluid of the user, and an electronics subsystem comprising a signal conditioning module that receives a signal stream, from the microsensor, wherein the electronics subsystem is configured to detect an impedance signal derived from two of the first working electrode, the second working electrode, the reference electrode, and the counter electrode; and a processing subsystem comprising: a first module configured to generate an analysis indicative of an analyte parameter of the user and derived from the signal stream and the impedance signal, and a second module configured to transmit information derived from the analysis to the user, thereby facilitating monitoring of body chemistry of the user.

The present disclosure discloses a guarding wall mechanism (100) for an optical fiber (101). The mechanism (100) comprises a housing (202) adapted to house the optical fiber (101), wherein the housing (202) defines a space (108) between the optical fiber (101) and a guarding wall of the housing (202). A plurality of suction units (103) disposed in the space (108). Each of the plurality of suction units (103) are configured to selectively exert suction pressure on an examination surface in contact with a free end (109) of the optical fiber (101). The guarding wall mechanism (100) of the present disclosure eliminates leakage of light and reduces Fresnel losses. Also, the mechanism (100) improves comfort to the patient during examination.

Percutaneous access devices (PAD), bandages, or other implantable medical devices are provided that are equipped with filters, environmental controls, and sensors that promote the formation of a natural biologic seal between the skin and the device to form a barrier to microbial invasion into the body. Levels of humidity and pressure are monitored and dynamically controlled to optimize wound closure about an implanted device or when a PAD is not present a wound itself. Methods and systems for actively assessing wound closure are incorporated into the design of percutaneous skin access devices (PAD), bone anchors, or a wound dressing or bandage alone without at PAD. Pressure and humidity sensors provide active feedback for making changes to the ecology of the wound site or PAD insertion site. A filter is used to aerate the wound while also preventing pathogens in the ambient air from reaching the wound.

Biomonitoring systems and methods of loading and releasing the same are disclosed herein. In one embodiment, a biomonitoring system includes a wearable sensor patch and an applicator. The sensor patch has a filament and an electronics subsystem. The sensor patch is configured to detect a parameter of an analyte in fluid of a user when it is adhered to the user's skin and the filament extends into the user's tissue. The applicator includes first and second applicator portions and a spring positioned within an interior of the second application portion between the first and second applicator portions. When the applicator transitions from a loaded mode to a released mode, the spring transitions from a first state of compression to a second, lower state of compression and accelerates the first applicator portion and the wearable sensor patch toward the user's skin such that the filament extends into the user's tissue.

Wearable sensor patches, applicator systems for applying wearable sensor patches, and associated systems, devices, and methods are disclosed herein. In one embodiment, an applicator system includes a first applicator portion, a second applicator portion, a spring, and a trigger mechanism. The first applicator portion releasably retains a wearable sensor patch configured to detect a parameter of an analyte in fluid of a user. When the applicator system is in a loaded mode, the spring and the first applicator portion are positioned within the second applicator portion such that the spring is positioned between the first applicator portion and the second applicator portion. The trigger mechanism is configured to initiate a transition of the applicator system from the loaded mode to a released mode such that the spring accelerates the first applicator portion distally away from the second applicator portion to apply the wearable sensor patch to the user.

Provided are devices and methods suitable for immobilizing tissue and for use in non-invasive methods of assessing lower urinary tract symptoms as well as in surgical application.

A medical imaging element support unit is for use in fixing a medical imaging element (26) releasably against a region of skin of a subject. The support unit includes a support body (14), having a base for engaging with skin of a subject in use and having a coupling means (22) for releasably coupling the medical imaging element (26) to the support body in use. A pneumatic positioning mechanism facilitates adjustment of a position of the medical imaging element relative to the support body, this being fluidly supplied by an air pump mechanism. The same air pump mechanism facilitates releasable fixation of the support body (14) to the skin, through creation of a configurable suction force at the skin engagement surface.
