  • Process for treating bone tissue and corresponding implantable biomaterials
    Patent number: 6217614
    Abstract: The present invention concerns a process for treating bone tissue of animal or human origin, and a corresponding implantable biomaterial. According to the present invention, a fluid in the supercritical state is caused to penetrate throughout the bone tissue. The bone tissue thus treated can then undergo stages of extracting specific proteins. This tissue is intended to be placed on a damaged bone tissue and has mechanical properties at least equivalent to those of natural bone.
    Type: Grant

  • Method for manufacturing and treating textiles
    Patent number: 6120558
    Abstract: A method for treating after its manufacture a textile structure containing at least one polymer of the poly (.alpha.-hydroxy-acids) family obtained by at least one step of mechanical assembly of textile fibers. The structure is contacted with a flow of a composition of at least one fluid in supercritical state. The invention also concerns a method for manufacturing a structure and the resulting structure.

  • Method for preparing an implantable composite material, resulting material, implant including said material, and kit therefor
    Patent number: 6018095
    Abstract: A method for preparing a composite material for implantation into a biological medium, by preparing at least one block of solid porous matrix including at least one calcium salt; preparing a liquid solution hardenable into a solid composition including at least one calcium salt; dipping the matrix block into the liquid solution; and drying and hardening the liquid solution. The resulting composite material, an implant including the material, and a kit for extemporaneously carrying out the method, are also disclosed.

  • Uses for a current of supercritical carbon dioxide as an antiviral agent
    Patent number: 5723012
    Abstract: The invention concerns the use with the aim of antiviral prophylaxis of a current of carbon dioxide CO.sub.2 in the supercritical state in contact with a tissue having a collagenous network of human or animal origin intended to be used as or in an implantable supporting tissue prosthesis as a biomaterial, wherein carbon dioxide in the supercritical state has the function of eliminating viral contamination from the tissue.
