Patent number: 9821163Abstract: Systems and methods are provided for treating a sexual disorder such as erectile dysfunction (ED) or female sexual arousal disorder (FSAD). An electrical stimulation system may include an implantable stimulation unit, an external patient controller, and an external physician controller. The implantable stimulation unit has an array of electrodes disposed on one or more flexible substrates configured to conform to a patient's anatomy at the pelvic plexus. Post-implantation, the physician controller may direct the stimulation unit to stimulate with select electrode(s) of the array to determine which electrode configuration provides optimal sexual arousal. The patient controller may be used to cause the stimulation unit to stimulate using the optimal electrode configuration at desired times.Type: GrantFiled: October 12, 2015Date of Patent: November 21, 2017Assignee: Ecole Polytechnique Federal De Lausanne (EPFL)Inventors: Rodrigo Araujo Fraga Da Silva, Nikolaos Stergiopulos

Patent number: 8963546Abstract: A method for performing magnetic resonance spectroscopy on solid samples containing nuclei of interest with spin quantum number I subjects the sample to a static magnetic field. The sample is spun at the magic angle and broad-band excitation of transverse magnetization of the nuclei of interest is effected by applying a first train of rotor-synchronized rf-pulses, having a carrier frequency, to the nuclei of interest with a pulse duration 0.1 ?s<?p<2 ?s, the first train of rf-pulses comprising k·n pulses extending over k rotor periods ?rot with n pulses per rotor period ?rot, wherein n is an integer n>1. Uniform excitation of a great number of spinning sidebands or families of sidebands that arise from large first-order quadrupole or hyperfine interactions is enabled and signal intensity is thereby improved.Type: GrantFiled: February 23, 2012Date of Patent: February 24, 2015Assignees: Bruker BioSpin AG, Ecole Polytechnique Fédéral de Lausanne (EPFL)Inventors: Simone Ulzega, Veronika Vitzthum, Geoffrey Bodenhausen, Marc Anthony Caporini

Publication number: 20140009341Abstract: Computerized systems and methods are provided for locating at least one object within a predefined cell or location. In accordance with one implementation, a location system is provided which comprises at least first and second receivers and first and second transmitters, respectively, including first and second internal clocks, the receivers and the transmitters, respectively, having known locations. The location system further includes a transmitter and a receiver, respectively, worn or carried by the object and designed to communicate by signal exchanges with the receivers and the transmitters, respectively. The location system further includes electronic circuits designed to compute position related information of the object based on the signal exchanges.Type: ApplicationFiled: February 19, 2013Publication date: January 9, 2014Applicant: ECOLE POLYTECHNIQUE FEDERAL DE LAUSANNE (EPFL)Inventor: ECOLE POLYTECHNIQUE FEDERAL DE LAUSANNE (EPFL)

Publication number: 20090081122Abstract: The injectable formulation for treatment by hyperthermia comprises a liquid carrier and heat-generating superparamagnetic iron oxide nanoparticles having a mean diameter not greater than 20 nm. Said injectable formulation is able to form in-situ a hyperthermic solid or semi-solid implant upon contact with a body fluid or tissue. Said hyperthermic solid or semi-solid implant may be useful for treating a tumor or a degenerative disc disease by hyperthermia.Type: ApplicationFiled: May 23, 2005Publication date: March 26, 2009Applicants: UNIVERSITE DE GENEVE, ECOLE POLYTECHNIQUE FEDERAL DE LAUSANNE (EPFL), HOPITAUX UNIVERSITAIRES DE GENEVEInventors: Daniel Rufenacht, Eric Doelker, Olivier Jordan, Mathiew Chastellain, Alke Petri-Fink, Heinrich Hofmann

Patent number: 6509174Abstract: Fluorescent protein expressing cells with very high fluorescence are described as well as a method to obtain such cells. The fluorescence of such cells can be as high as about 1000 times the auto-fluorescence of the respective host cell. Due to the high fluorescence, said cells are very suitable tools in the development, surveillance and/or optimization of production processes, for selection of culture media and process parameters and for the determination of cell growth and the detection, quantification and monitoring of biomass.Type: GrantFiled: June 16, 1998Date of Patent: January 21, 2003Assignee: Ecole Polytechnique Federal de Lausanne (EPFL)Inventors: Martin Jordan, Florian Maria Wurm
