Abstract: A percutaneous bypass method for implanting a bypass graft between two vessels is described. The bypass graft comprises a first part and a second part, each having a tubular shape and comprising respective lumens. The method comprises the step of inserting a second sheath, from the outside to the inside of a bypass portion of the first part, through a puncture therein, and retracting the second sheath so as to deploy and implant a hook portion of the second part into the second vessel, and deploy a bypass portion of the second part outside the second vessel, from the second vessel to the first part, and within the lumen of the first part.

Abstract: A vascular prosthesis configured to be implanted in a vessel, having substantially a T-shape, comprises a proximal tubular part forming the base of the “T” and a distal tubular part forming the head of the “T”. The proximal tubular part has a first lumen, the distal tubular part has a second lumen, and the first and second lumens are fluidly connected to form a common lumen. The distal tubular part comprises a first end portion, a second end portion, and an intermediate portion extending axially between the first and second end portions. The first and second end portions are radially expandable. The proximal tubular part is connected to the intermediate portion and the second end portion is movable between a retracted position in which the second end portion is axially restrained and a deployed position in which the second end portion is axially deployed.

Abstract: This disclosure relates to a method for characterising a target object in a medium. The method comprises: obtaining a reference matrix F(q) associated with the target object, measuring a reflection matrix R associated with the probed medium, and projecting the reflection matrix R onto the reference matrix F(q) to estimate a probability P(q) that the object is in a state q.

Abstract: A vehicle driving and monitoring system includes an driving system including a situation analysis and planning unit, configured to determine vehicle situation information; a vehicle situation summary determination system configured, based on the vehicle situation information, to calculate a situational image; the situational image being a surround view of the vehicle calculated so that: at least one stationary element or mobile object which is located within an outline defining the situational image is not shown in the situational image or is shown in a less visible way, and/or additional driving information is shown in the situational image; and a vehicle situation summary output system including a display device configured to continuously display the situational image when the vehicle is moving.

Abstract: A vascular prosthesis may be implanted in a vessel, having substantially a T-shape, that includes a proximal tubular part forming the base of the “T” and a distal tubular part forming the head of the “T”. The second end portion of the distal tubular part is formed by a flap. The flap is opposed to a circumferential indentation in the deployed position. The structural frame of the flap includes an arched segment connected at its ends to the intermediate portion of the distal tubular part. The arched segment is bendable so as to form a joint for the folding/unfolding movement of the flap.

Abstract: Reactor allowing the continuous filtration of a flowing fluid for the adsorption of pollutants on a filter, and electrolysis for regeneration of the filter and removal of organic pollutants, the reactor having a chamber, with at least one inlet delivering a fluid into the chamber and at least one outlet for evacuating the fluid from the chamber; a circuit for circulating a fluid to be treated by adsorption of pollutants on the filter; a circuit for recirculating an electrolyte solution for electrolysis, connecting the outlet to the inlet; the reactor operating in two modes; in continuous filtration mode of a fluid through the circulation circuit for adsorption of pollutants on the filter; in electrolysis mode for regeneration of the filter and removal of organic pollutants, by applying an electric current, with continuous recirculation of the electrolyte solution through the recirculation circuit.

Abstract: A method of improving the efficiency of an electrically small antenna (1), the method comprising the following steps: selecting (100) an antenna; electrically feeding said selected antenna (1); quantifying (110) the energy stored in the selected antenna (1) at a given transmission frequency; determining the nature of the antenna (1) as a function of the quantified stored energy, this determination comprising comparing (120) said quantity of stored energy with an energy threshold, the antenna (1) being of electric nature (130) if the quantified stored energy is below the energy threshold, and otherwise being of magnetic nature (135); and selecting a metamaterial inclusion (2) for associating with the selected antenna (1) in order to improve its efficiency, the selection being made from a list of inclusions as a function of the nature of the selected antenna (1).
