Bioresorbable and biocompatible compounds for surgical use

A bioresorbable and biocompatible compound for surgical use is composed of functionalized collagen cross-linked with a glycosaminoglycan.

Method for Preparing Chitosan Matrices Having Improved Mechanical Properties

The present invention relates to a method for preparing a chitosan matrix having good mechanical properties comprising the steps of a) preparing a solution of chitosan, b) pouring the solution of a) into a mould in order to form a layer, c) lyophilizing the layer of b) in order to obtain a matrix of chitosan, d) sterilizing the matrix obtained in c) by water vapor treatment. The invention also relates to the matrices obtained and to surgical implants comprising such matrices. The invention further relates to a method for increasing the suture retention strength of a chitosan matrix obtained by lyophilization of a chitosan solution, and to a method for for decreasing the solubilization rate in hydrochloric acid of a chitosan matrix obtained by lyophilization of a chitosan solution, comprising the step of sterilizing said matrix by a water vapor treatment.

Crosslinked fibers and method of making same by extrusion

The present disclosure relates to a method of forming fibers. First and second precursors, each possessing a core and at least one functional group known to have click reactivity, are mixed. The mixed precursors are then extruded under heat to cross-link during fiber production.

Optimized chitosan reacetylation

Hernia prosthesis

The present invention relates to a prosthesis (200) comprising:—at least one layer of a flexible mesh (1) delimited by a peripheral outer edge (1a), said mesh having a first color, and—at least one layer (2) of porous material fixed to said mesh substantially along the perimeter of said peripheral outer edge, said layer of porous material being recessed at its central part (4), said layer of porous material having a second color, different from said first color.
