Patent number: 11534338Abstract: The invention relates to a system for laser photocoagulation of the retina, comprising: a photocoagulation laser (1); an optical path (5) connecting the upstream photocoagulation laser (1) to a downstream laser outlet opening (6) intended to be positioned in front of the retina; an adaptive optical element (9) positioned in the optical path and configured to modify the wavefront of the laser beam being propagated in the optical path, in order to compensate for aberrations of the eye that occur as far as the retina; a position control loop (10) controlling a first actuator (14) positioned in the optical path downstream of the adaptive optical element in order to control the position of the laser outlet opening relative to the retina to be treated; and at least one imaging device (8) configured to obtain an image of the retina diverted from the optical path.Type: GrantFiled: April 25, 2019Date of Patent: December 27, 2022Assignees: QUANTEL MEDICAL, OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES (ONERA)Inventors: Christian Chabrier, Serge Meimon, Patrice Gayot, Cyril Petit, Pedro Baracal De Mece, Benjamin Wassmer

Publication number: 20200008777Abstract: The invention relates to a method for ocular ultrasound using an ultrasound probe comprising a plurality of transducer elements organised in at least n concentric rings forming n transducer rings (2, 2a, 2b, 2c, 2d, 2e), the transducer rings being grouped together in k groups of rings. Said method comprises the following steps: for each cycle (100, 110, 200, 210, 300, 310) of a plurality of cycles of k iterations using a different group of transducer rings and working through the groups of transducer rings: exciting a group of transducer rings in order to emit ultrasound waves; collecting n measuring signals from the n transducer rings; combining the n measuring signals in order to provide an ultrasound line representing the response of the n transducer rings when ultrasound waves are emitted; combining k ultrasound lines resulting from the most recent k iterations into a displayable line; and treating and displaying the displayable lines.Type: ApplicationFiled: February 21, 2018Publication date: January 9, 2020Applicant: QUANTEL MEDICALInventors: Christian CHABRIER, Cédric VENUAT

Patent number: 10463540Abstract: A photocoagulation system is described herein that facilitates multi-spot laser treatment procedures inside the eye and close to the patient's retina. In one example embodiment, a modified endocular probe operates with a laser system to move the probe or a probe needle so as to project a multi-spot pattern on a patient's retina by controlling the rotation movement of the needle (and needle tip). In addition, the system facilitates maneuverability and angular deviation of the needle tip and synchronizes these different movements with the laser photocoagulator system so as to project the aiming beam and thereafter the laser treatment beam in the desired pattern location with the desired exposure time and power.Type: GrantFiled: December 22, 2014Date of Patent: November 5, 2019Assignee: Quantel Medical, Inc.Inventors: Christian Chabrier, Patrice Gayot

Patent number: 9676117Abstract: There is a method for producing a ply involved in the construction of a multi-ply panel for constructing or adding to a wall, floor or ceiling, or a sloping part for a building. The ply includes a juxtaposition of strips, either structural strips or filling strips, positioned between the structural strips and made of a different material from that of the structural strips. The materials are selected for the thermal or acoustic insulation thereof, the thermal inertia thereof or the fire résistance thereof. Each lateral movement of a ply being produced with respect to the assembly plane is carried out by the synchronized movement of a table with which the lower face of the ply is in contact and a driver with which the upper face of the ply is in contact. There is an installation for implementing the method according to the invention.Type: GrantFiled: May 9, 2012Date of Patent: June 13, 2017Assignee: Techniwood InternationalInventors: Bruno Raudin, Pascal Faure, Christian Chabrier

Publication number: 20150218811Abstract: The multi-ply panel for forming or adding to a wall, floor, or ceiling, or for the inclined surface of a building includes a stack of layers. At least one layer is formed of parallel structural strips, preferably made of wood. Filler strips are placed between the structural strips and made of a different material than that of the structural strips. The materials may be selected for the heat or sound insulation properties, thermal inertia, or fire-resistant properties thereof. At least one rigid filler strip is made of an insulating material with heat conductivity less than 0.038 W/m·K.Type: ApplicationFiled: April 11, 2012Publication date: August 6, 2015Applicant: TECHNIWOOD INTERNATIONALInventors: Laurent Bourdon, Pascal Faure, Didier Goy, Christian Chabrier
