  • Bioactive Biomaterials for Controlled Delivery of Active Principles
    Publication number: 20080004398
    Abstract: The invention relates to biomaterials comprising a carrier material to which surface spherical particles are covalently linked, wherein said spherical particles are formed by polymer chains containing approximately from 30 to 10000 monomer units derived from monocyclic polycyclic alkene polymerisation, are substituted by an R chain comprising ethylene polyoxide which is optionally covalently linked to said polymer units through a hydrolysable bridge and substituted by a reactive function engaged in a link with an active principle, said chain R being covalently linked to said monomer units. The use of the inventive biomaterials for preparing pharmaceutical and cosmetic compositions or surface coatings is also disclosed.

  • 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.

  • Biocompatible, hydrophilic material, method of manufacture and uses of same
    Patent number: 5152793
    Abstract: A biocompatible hydrophilic material is based on purified cellulose, from which material all or the majority of the water has been removed and which has a modulable potential for water recovery of up to an amount of water of approximately 60%. The material can be used for the production of fitting sheaths for articulated prostheses.
