Title (EN) CALENDERED SURGICAL MESHES COMPRISING POLYHYDROXYALKANOATES
(FR) TREILLIS CHIRURGICAUX CALANDRÉS COMPRENANT DES POLYHYDROXYALCANOATES
Abstract:
(EN) Calendered surgical meshes comprising polyhydroxyalkanoate polymers have been developed. These meshes, preferably made from poly-4-hydroxybutyrate or copolymer thereof, have a thickness that is between 50 to 99% of the thickness of the mesh prior to calendering, and a burst strength that is not less than 20% of the burst strength of the mesh prior to calendering. The thinner calendered meshes are particularly suitable for surgical applications where a thinner profile mesh with high burst strength is required, and where it is advantageous to have a mesh with a smooth surface. The meshes may be partially or fully resorbable, and are particularly suitable for use in the treatment of pelvic organ prolapse.
(FR) Selon la présente invention, des treillis chirurgicaux calandrés comprenant des polymères de polyhydroxyalcanoate ont été développés. Ces treillis, de préférence constitués de poly-4-hydroxybutyrate ou un copolymère de celui-ci, ont une épaisseur qui est comprise entre 50 et 99 % de l'épaisseur du treillis avant le calandrage, et une résistance à l'éclatement qui n'est pas inférieure à 20 % de la résistance à l'éclatement du treillis avant le calandrage. Les treillis calandrés plus minces sont particulièrement adaptés pour des applications chirurgicales dans lesquelles un treillis de profil plus mince ayant une résistance à l'éclatement élevée est requis, et dans lesquelles il est avantageux de disposer d'un treillis avec une surface lisse. Les treillis peuvent être partiellement ou totalement résorbables, et sont particulièrement adaptés pour utilisation dans le traitement d'un prolapsus des organes pelviens.
