Publication number: 20240115371Abstract: 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.Type: ApplicationFiled: April 6, 2022Publication date: April 11, 2024Applicants: UNIVERSITÉ D'AIX MARSEILLE, ASSISTANCE PUBLIQUE-HÔPITAUX DE MARSEILLE, Université Gustave Eiffel, Bypass SolutionsInventors: Yves Simon Alimi, Frédéric Mouret, Vincent Garitey, David Baas

Publication number: 20230372078Abstract: 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.Type: ApplicationFiled: October 6, 2020Publication date: November 23, 2023Applicants: UNIVERSITÉ D'AIX-MARSEILLE, ASSISTANCE PUBLIQUE - HÔPITAUX DE MARSEILLE, Université Gustave EiffelInventor: Yves Alimi

Publication number: 20220370192Abstract: 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.Type: ApplicationFiled: October 5, 2020Publication date: November 24, 2022Applicants: Université d'Aix-Marseille, ASSISTANCE PUBLIQUE - HÔPITAUX DE MARSEILLE, Université Gustave EiffelInventors: Yves Simon Alimi, Frédéric Mouret, Vincent Garitey

Patent number: 10816511Abstract: The invention relates to a method for detecting defects of at least one metal wire of a set of metal wires, in particular in a cable, the method including: a step of emitting a high-frequency ultrasound signal around a so-called specific frequency in the metal wire; a step of reflecting said ultrasound signal in the metal wire; and a step of receiving the reflected ultrasound signal. The emitted ultrasound signal enables the energisation of at least one high-frequency wave capable of propagating in a longitudinal direction of the metal wire and having a phase velocity that is slightly higher than a compression volume wave velocity in the metal from which the metal wire is made.Type: GrantFiled: March 24, 2016Date of Patent: October 27, 2020Assignees: SOLETANCHE FREYSSINET, UNIVERSITE GUSTAVE EIFFELInventors: Laurent Laguerre, Olivier Durand, Remi Colin
