  • Biomaterial based on an insolubilized dextran derivative and a growth factor
    Patent number: 6946443
    Abstract: The invention concerns a biologically active material essentially comprising at least an insolubilized dextran derivative of general formula DMCaBbSUcSd and at least a growth factor having an activity on osteoarticular, dental and/or maxillofacial tissues, and the method for preparing same. The invention also concerns the uses of said biomaterial for preparing a repair or filing material, such as an implant, for osteoarticular, dental or maxillofacial applications and for preparing an orthopaedic, dental or maxillofacial prosthesis, and the prosthesis coated with said biologically active material.

  • Process for cross-linking of collagen by diphenylphosphorylazide the cross-linked collagen obtained thereby and collagen-based biomaterials thus cross-linked
    Patent number: 5264551
    Abstract: The invention relates to a process of cross-linking collagen. This process is of the type comprising the formation of amide bonds by means of acylazide groups and is characterized in that the collagen is reacted with diphenylphosphorylazide. The process according to the invention makes it possible to simplify the collagen cross-linking process and to adjust the degree of cross-linking at discretion without introducing any cross-linking agent.

  • Process for crosslinking of collagen by introduction of azide groups as well as tissues and biomaterials obtained by use of the process
    Patent number: 4958008
    Abstract: This process, which essentially comprises the following steps:esterification of the free acid groups of the collagen,transformation of the esterified groups into hydrazides groups,transformation of the hydrazide groups into azide groups by the action of nitrous acid, is characterized in that each step is separated by a rinsing in an aqueous salt solution, and in that the step of transformation of esterified groups into azide groups and the step of transformation of hydrazide groups into azide groups by the action of nitrous acid, are performed in the presence of salt.
