Abstract: Described herein is a multi-dimensional kineticardiography device (300) which comprises a sensor (320) having three accelerometer/gyroscope modules (320X, 320Y, 320Z) mounted in a support which positions it at the centre of mass of a subject whose cardiac function is to be measured. The sensor (320) outputs six degrees of freedom data as linear acceleration along and rotational or angular velocity about x-, y- and z-axes. The sensor (320) is connected to a processor (335) for transmitting the kineticardiography data obtained from the sensor (320) and the electrocardiography data to a mobile computing platform (330), via Bluetooth (350), for further processing and display. An electrocardiography data chip (370) is also present for digitising the electrocardiography data for further processing.

Abstract: A data processing system for predicting a score representative of a probability of a sepsis for a patient includes a data interface configured to receive, from at least one database, health data of at least one patient. The data processing system includes a trained machine learning model configured to predict and provide the score using as input the health data for each patient, and to provide a plurality of sub-scores representative of a correlation between the health data and the predicted score. In this regard, the health data includes regularly updated biometric monitoring data provided by a biometric monitoring device and health history data provided by at least one health history database.

Abstract: A system to localize a micro-device inside a target body part, including: a micro-device remotely steered and controlled from outside the target body part, a control unit including a memory for storing one ultrasound image of the target body part, one probe being brought in contact with a securing body part of the patient, and at least one tracker connected to the micro-device. The probe and the tracker communicate with ultrasounds, the control unit being thus able to localize, in real time, the tracker within an internal referential defined with regards to the probe, and the control unit displays, on a screen, the ultrasound image and displays, in real time, the localization of the micro-device on the ultrasound image.

Abstract: A signal tracking system including: one fixation element to be secured to a rigid body part of the patient surrounding a target body part, the fixation element further including a mapping element, one tracker element to be secured to the fixation element to track, in real time, the internal tracker, and a control unit including a memory to store an internal referential and one image displaying the target body part and one fixation element. The control unit is designed to define, inside the internal referential, at least one 3D frame position attached to the at least one fixation element, and to precisely locate each point of the target body part, the control unit is further designed to precisely localize, in real time, the internal tracker inside the target body part.

Abstract: A delivery and gathering system for at least one target point inside a target body part of a patient, the system including: a microrobot aimed at navigating towards the at least one target point, a cap aimed at being secured to a securing body part of the patient, the cap including a channel which enables to introduce elements into the target body part, or enables to remove elements from inside the target body part, a wire connected to the microrobot and to the cap, and a control unit configured to communicate with the cap, the control unit including a user interface enabling a user to remotely control and navigate the microrobot. The system further includes a flexible elongated element configured to cooperate, by sliding, with the wire in order to extend, from the cap, towards the target point.
