Latest Patents
One of Montembault's latest patents is for a chitosan hydrogel designed for repairing nerve tissue. This invention involves chitosan hydrogel microparticles with a median size of d50 between 1 and 500 µm. The chitosan used has a degree of acetylation of less than or equal to 20%, and its concentration in the hydrogel ranges from 0.25 to 5% by weight. This hydrogel is intended for use in neuron regeneration, repair of the nervous system, and treatment of neurodegenerative diseases. Additionally, it includes an implant that comprises an aqueous suspension of microparticles mixed with Schwann cells, stem cells, or trophic factors.
Another significant patent involves a method for obtaining an elongate polysaccharide element, specifically a chitosan thread. This method includes extruding a hydroalcoholic solution containing a polyalcohol of the polysaccharide through an extrusion die. The process ensures that the resulting chitosan thread possesses mechanical strength and flexibility, allowing it to
