Patent number: 8733394Abstract: A device for mechanically locating and reading the setting of an adjustable magnetic valve for controlling the flow of a fluid in a predetermined direction (D) comprises a magnetic compass (10) and a selector (20) provided with an alignment mark (21) for aligning the magnetic compass (10) with respect to the direction (D) in which the fluid flows through the valve (V). The compass (10) comprises a reference plane and a magnetic indicator (12) which is mounted such that it can pivot in all three dimensions of space under the effect of the magnetic field of the valve, the valve setting being represented by the angle (?) formed, in the reference plane, between the magnetic indicator (12) and the alignment mark (21) when the magnetic indicator (12) is positioned perpendicular to the reference plane, the magnetic compass then being centered on the magnetic center of the valve.Type: GrantFiled: September 10, 2007Date of Patent: May 27, 2014Assignee: SophysaInventors: Philippe Negre, Christophe Moureaux, Jean-Philippe Lemaitre

Patent number: 7850719Abstract: Orthopedic implants are disclosed that may be used in spinal applications. In one embodiment, a plate portion is provided with a threaded protrusion on which a connector for attachment to an orthopedic rod can be fitted. The protrusion may be multi-axially orientable with respect to said plate portion. The plate portion may include a dome having an inner surface that may be of conical shape, through which a portion of the protrusion may extend. A pin may be provided to retain the protrusion in place with respect to the dome. A second plate portion may be provided, which may be integral with or movable with respect to the first plate portion, that can be connected to a bone, e.g. iliac or sacral bone.Type: GrantFiled: May 25, 2005Date of Patent: December 14, 2010Assignee: Warsaw Orthopedic, Inc.Inventors: Jose Gournay, Philippe Lemaitre, Ezzine Banouskou

Patent number: 7572277Abstract: A connector (1) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice (2) opening onto two opposed faces (3, 4) of the connector (1), and two other orifices (5, 6) opening onto two other opposed faces (7, 8) of the connector (1). Each of the two other orifices (5, 6) are each designed to receive a rod (14, 15) of the osteosynthesis device. The connector (1) includes a mechanism making it possible, when the connector (1) is push-fitted onto a protrusion (100) of a bone anchor member, to tighten the rods (14, 15) simultaneously in the two other orifices (5, 6) when a nut (22) is screwed onto the protrusion (100). An assembly for spinal osteosynthesis device includes a plate (16) that includes a protrusion (100), a connector (1) as previously described, and a nut (22).Type: GrantFiled: January 30, 2003Date of Patent: August 11, 2009Assignee: Warsaw Orthopedic, Inc.Inventors: Pierre Roussouly, Daniel Chopin, Laure Bruneau, Philippe Lemaitre

Patent number: 4896115Abstract: An insulation monitoring device comprises an input circuit of a reference AC signal, and an electronic detection circuit for discriminating the components of a measurement signal proportional to the ground fault impedance Z formed by a leakage resistor Rf in parallel with a leakage capacitor C. A synchronous detector has a pair of static inverters processing the first component, which is a function of the current IR flowing through the leakage resistor Rf, and of the second component which is a function of the current IC flowing through the capacitor C. A converter cooperates with the generator to deliver two quadrature signals C1 and C2 to respectively control the inverters. A display means accurately displays the value of the leakage resistance Rf.Type: GrantFiled: June 1, 1988Date of Patent: January 23, 1990Assignee: Merlin GerinInventors: Philippe LeMaitre, Philippe Schuster, Christian Pellegrin
