Publication number: 20130261622Abstract: Surgical implant for treating fractures of long bones, notably of the femur, having an intramedullary section (52) of elongated shape, adapted for being inserted into the medullary cavity (37), an extramedullary section (56) substantially parallel to the intramedullary section (52), a deformable curved loop (57) connecting the intramedullary section (52) to the extramedullary section (56), an inclined screw (61) traversing said intramedullary section (52) and said extramedullary section (56). By deforming the loop (57), a continuous adjustment of the angle (?) of the cephalic screw (61) and thus an optimal adaptation of the implant to the individual anatomy can be achieved. Thanks to its geometry, this implant induces a protection of the greater trochanter and limits the mechanical loads between the cephalic screw (61) and the rest of the implant.Type: ApplicationFiled: March 14, 2013Publication date: October 3, 2013Applicants: Chirmat Sarl, Tural, Hepia, Universite de SavoieInventors: Christian BONJOUR, Yvan ARLETTAZ, Pierre VACHER, Franck TOUSSAINT, Remi BILLARD, Laure DEVUN, Thomas GRADEL, Eric VITTECOQ

Patent number: 8264685Abstract: A device for measuring two components of an electromagnetic field in an analysis zone includes a light source for sending a polarized light beam into a polarization-maintaining optical fiber. The beam is directed along one axis of the fiber. An isotropic electrooptic material is placed in the zone for receiving the beam from the optical fiber via a substantially quarter-wave plate, which has its axes oriented at an angle of substantially 45° to the axes of the optical fiber and for sending a beam into the fiber. The plate is slightly detuned in regard to its characteristics or its orientation. The device further includes a phase-shifter for phase-shifting the beam sent into the fiber, wherein the phase-shifter is set so as to impose a phase shift equal and opposite to that imposed by the fiber and mechanism for analyzing the orientation and ellipticity of the wave exiting the phase-shifter.Type: GrantFiled: June 15, 2007Date of Patent: September 11, 2012Assignees: Institut National Polytechnique de Grenoble, Universite de SavoieInventors: Lionel Duvillaret, Gwenaël Gaborit
