Patent number: 9095663Abstract: A filtration unit intended to allow the selective elimination of target substances from a fluid such as flood or a blood component, has an outer envelope formed from two flexible sheets joined together over their periphery along a bond line so as to define an inner volume, the envelope containing a filtering medium which delimits, on both sides of the bond line, an inlet compartment of the fluid to be filtered and an outlet compartment of the filtrate, each of the compartments being provided with an element—respectively an inlet and outlet element—for bringing the compartment into communication with the outside, the elements being connected between the sheets and comprising a flow channel that passes through the bond line, the unit being characterized in that at least one channel is offset relative to the bond line towards the compartment with which the channel is in communication.Type: GrantFiled: April 22, 2008Date of Patent: August 4, 2015Assignee: MACO PHARMAInventors: Robert Duhaut, Chryslain Sumian, David Godard

Publication number: 20070154536Abstract: Methods for enhancing penetration of compounds/drugs into an animal or human through their hair follicles are provided. The methods employ topical application of swellable compositions which can maintain a passage for desired drugs by either opening hair follicles and preventing them from collapsing or increasing the depth of inner lumen space of the hair follicles. The swellable composition can be polymers that are biodegradable, bioactive, encapsulated in microspheres or liposomes, and/or form microspheres. The method is useful to increase compound/drug penetration deep into a patient, to increase flux of compounds/drugs through the hair follicle, to obtain release of compounds/drugs in the tissues surrounding hair follicle or under the skin surface, and to obtain a systemic effect of the compounds/drugs after topical application. The method is also useful to increase therapeutic effects of compounds/drugs in the treatment of a wide variety of skin disorders.Type: ApplicationFiled: February 15, 2007Publication date: July 5, 2007Inventor: Chryslain Sumian

Patent number: 6685927Abstract: A device and method is disclosed for permanent or semi-permanent removal of hair through the activation of microparticles introduced into hair follicles. Microparticles are incorporated into a composition that is topically applied to the skin. These microparticles containing or consisting of chromophores or chemically activated molecules are of a variety of shapes and sizes. Microparticles are within a size range of 1 micron to 70 microns, and preferably between 10 and 50 microns. Microparticles of this size and variety of shapes enter hair follicles on all areas of the skin without entering other areas of the skin, such as the stratum corneum or sweat gland channels. Treatment of the skin with electromagnetic radiation, ultrasonic radiation or chemical means activates the chromophore or chemically activated compounds, thus destroying the hair follicle without damaging other areas of the skin.Type: GrantFiled: September 27, 2001Date of Patent: February 3, 2004Assignee: CeramOptec Industries, Inc.Inventors: Chryslain Sumian, Wolfgang Neuberger, Serge Mordon

Patent number: 6562025Abstract: The apparatus for uniting the lips of a wound comprises a laser having an emission wavelength chosen such that it can perform tissue bonding and unite the lips of a wound, and a holding piece suitable for being secured to the tissue around the wound so as to keep the lips of the wound approximated, at least while the wound is being exposed to said laser radiation, the holding piece including at least one region suitable for being positioned over the wound and sufficiently transparent at the wavelength of the laser radiation for the energy from said radiation to be sufficient, after it has passed through said region, to perform the desired tissue bonding.Type: GrantFiled: July 22, 1999Date of Patent: May 13, 2003Assignee: Galderma Research & Development, S.N.C.Inventors: Serge R. Mordon, Alexandre Capon, Chryslain Sumian

Patent number: 6340495Abstract: The invention relates to device making it possible to apply a chromophoric composition to the skin, said device including a chromophoric composition containing at least one chromophoric agent. The chromophoric composition is in the form of a layer of constant thickness bonded to one face of backing, at least prior to being applied to the skin, the chromophoric agent or agents being distributed uniformly in said composition, and the type of the composition being chosen such that light energy from laser radiation is transformed locally into heat and/or the chemical structure(s) of the chromophoric agent(s) is/are modified locally.Type: GrantFiled: December 9, 1998Date of Patent: January 22, 2002Assignee: Galderma Research & DevelopmentInventors: Chryslain Sumian, Franck Pitre, Serge Mordon

Patent number: 6287549Abstract: A method for eliminating unwanted hairs is provided. The method includes applying an effective amount of a composition including microparticles to the surface of the skin where the hairs are situated and removing the composition remaining on the surface of the skin. The microparticles contain chromophores and a second material different from the chromophores. At least 80% by weight of the microparticles have a diameter of between 3 &mgr;m and 10 &mgr;m. A composition containing a solvent which dissolves the chromophores may then be applied to the surface of the skin. Laser radiation is then applied in one or more shots. The emitted wavelength of the laser radiation is absorbed by the chromophores. The light energy and the emission duration of the laser energy are sufficient to damage and/or kill the cells responsible for the growth of the hair.Type: GrantFiled: December 22, 1999Date of Patent: September 11, 2001Assignee: Centre International de Recherche Dermatologiques Galderma (C.I.R.D.)

Patent number: 6086580Abstract: Mammalian skin is treated and advantageously smoothed, for example to remove wrinkles, lines, warts and scars therefrom, by topically applying thereto a composition which comprises at least one laser-absorbing chromophore formulated into a physiologically acceptable carrier, diluent or vehicle therefor, and laser-irradiating the skin thus treated with an intensity sufficient to locally convert the light energy into heat energy in the applied composition and advantageously effecting tissue ablation of the surface of the treated skin, said applied composition and the thickness thereof having an absorbance at the emission wavelength of the laser such that the light energy transmitted into the skin generates no undesired irreversible tissue or cell damage.Type: GrantFiled: December 5, 1997Date of Patent: July 11, 2000Assignee: Centre International de Recherches DermatologiquesInventors: Serge Mordon, Chryslain Sumian, Karine Buffard, Franck Pitre, Martine Bouclier
