Abstract: An indwelling medical device with stimuli-responsive antimicrobial properties. The medical device includes a polymeric substrate having one or more light-responsive antimicrobial compounds. The medical device includes a light source to provide light to the polymeric substrate and a sensor to detect infection or bacterial colonization. A controller is connected to the light source and to the sensor. The controller controls operation of the sensor and receives sensing signals from the sensor. The controller activates the light source in response to infection detection and release the antimicrobial compound. The light-responsive antimicrobial compound may include a nitric oxide donor, such as S-nitroso-n-acetylpenacillamine, S-nitrosoglutathione, or N-diazeniumdiolate (NONOate). The light-responsive antimicrobial compound may include a photocatalyst metal oxide, such as ZnO, CuO, or TiO2. The light-responsive antimicrobial compound may include a photosensitive dye, such as crystal violet, methylene blue ethyl violet, rose bengal, or malachite green.

Abstract: Embodiments of the present disclosure include a method for receiving sensor data indicative of a glucose level from a glucose sensor configured to be positioned in contact with a bodily fluid under a skin surface of a subject, receiving, from a temperature sensor, temperature data indicative of a temperature of the skin surface, determining a rate of change of the glucose level, wherein the rate of change indicates a presence of a hypoglycemic condition, determining that a variation of the temperature of the skin surface is within a predetermined range of temperature values, and determining, in response to the variation of the temperature data, that the rate of change of the glucose level corresponds to a sensor signal attenuation.

Abstract: A core body temperature sensor (10) includes a thermoresistant structure (12) having a proximal surface (11) configured for attachment to skin of an associated patient, and a distal end (13) opposite from the proximal surface. A plurality of temperature sensors (14) is arranged to measure temperatures of the thermoresistant structure at a corresponding plurality of different distances from the proximal surface of the thermoresistant structure. A temperature-changing element (16) is configured to change a temperature of the distal end of the thermoresistant structure. An electronic processor (20) is programmed to acquire temperature measurements from the plurality of temperature sensors while operating the temperature-changing element to maintain a temperature of the distal end of the thermoresistant structure at a temperature different from an ambient temperature, and extrapolate a core body temperature of the associated patient from the acquired temperature measurements.

Abstract: A method of facilitating therapeutic neuromodulation of a heart of a patient includes positioning an electrode in a pulmonary artery, positioning a sensor in vasculature, delivering via a stimulation system first and second electrical signals of a series of electrical signals to the electrode. The second electrical signal differs from the first electrical signal by a magnitude of a first parameter of a plurality of parameters. The method includes determining, via the sensor, sensor data indicative of one or more heart activity properties in response to the delivery of the series of electrical signals, and delivering a therapeutic neuromodulation signal to the pulmonary artery using selected electrical parameters. The selected electrical parameters include a selected magnitude of the first parameter. The selected magnitude of the first parameter is based at least partially on the sensor data. The therapeutic neuromodulation signal increases heart contractility.

Abstract: The disclosure deals with methodology and involved or associated systems for using infrared technology to detect tissue damage below the skin. Pressure and shear stress can damage the microvascular structure below the skin, which is not visible to the naked eye. Infrared thermography is a non-invasive mechanism to measure skin temperature via thermal radiation. Changes (restrictions) in blood flow below the skin can result in microvascular damage to the tissue, and directly impact skin temperature, which can be detected by infrared thermography. Infrared thermography can detect these changes at the site of tissue damage. This disclosure uses affordable infrared thermography to detect changes in temperature related to blood flow alterations, supported with AI. Using serial images, AI can detect an emerging DFU (Diabetic Foot Ulcer) in DM (Diabetes Mellitus) patients through deviations in skin temperature.
