Alain le Moel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Fluid treatment module having hollow membranes
    Patent number: 7189321
    Abstract: The invention relates to a hollow membrane (11) comprising two support layers arranged one above the other forming a space between them and a plurality of capillary tubes arranged between the support layers forming capillary channels for the flow of a first fluid, the space between the capillary tubes forming an internal cavity for the circulation of a second fluid around the capillary tubes, and the whole assembly being made of an organic polymer. These membranes (11) can be assembled into modules for the treatment of a fluid with intermediate porous panels (13).
    Type: Grant

  • Bioactive prostheses with immunosuppressive, antistenotic and antithrombotic properties
    Patent number: 6517858
    Abstract: The invention relates to a bioactive implant comprising a substrate coated with a polymer layer with reactive functions, and a bioactive substance fixed on the implant by means of said reactive functions to enable progressive release on the implant site. Such implants are useful in the field of cardiology for example to prevent restenosis resulting from the fitting of stents in the coronary arteries.

  • Films having in their thickness at least two superimposed zones, including an insulating zone and a conductive zone, and the production thereof by irradiating a polymer film by means of a beam of high energy ions
    Patent number: 4983460
    Abstract: The invention relates to the production of films having in their thickness at least two superimposed zones, including a semimetallic zone and an electrically insulating zone, by irradiating a polymer film by means of a high energy ion beam.It is possible by this process to produce semimetal (1)/insulant (2)/semimetal (3) structures by irradiating the polymer under vacuum by means of light ions or with a limited stopping power having an energy of at least 1 MeV/amu. It is also possible to obtain insulant (4)/semimetal (5)/insulant (6) structures by irradiating, in a confined atmosphere, the polymer by means of heavy ions or ions having a high energy loss with by energy of least 1 MeV/amu.By irradiating only certain zones of the film, it is thus possible to form embedded or surface-positioned electrical connections.
