Title (EN) CARTILAGE REPAIR UNIT
(FR) UNITE DE REPARATION DU CARTILAGE
Abstract:
(EN) A bio-absorbable cartilage repair system (10) is provided for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a condrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone. The system (10) is an assembly (12) of a delivery unit (14) and a porous insert (16). The delivery unit (14) is formed of bio-absorbable material and configured and dimensioned to be mounted in both an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone. The delivery unit (14) has a central body (26) and a plurality of radially extending, flexible support arms (28) projecting outwardly from the central body and configured and dimensioned to support the insert (16) at least partially thereover. The insert (16) is supported by the delivery unit (14), formed of bio-absorbable material, and establishes communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix.
(FR) L'invention concerne un système de réparation du cartilage bioabsorbable permettant de régénérer un cartilage articulaire abîmé ou détruit sur une surface d'articulation d'un os, ce système formant une matrice de croissance chondrogénique entre la zone d'un cartilage articulaire abîmé ou détruit ayant été retirée et la zone adjacente saine d'un cartilage articulaire et d'un os spongieux sous-chondral. Le système de cette invention se présente sous la forme d'un ensemble composé par une unité de mise en place et un insert poreux. Les dimensions de l'unité de mise en place, qui est fabriquée dans un matériau bioabsorbable, permettent à celle-ci d'être montée à la fois dans la zone d'un cartilage articulaire abîmé ou détruit ayant été retirée et dans la zone adjacente saine d'un cartilage articulaire et d'un os spongieux. Cette unité de mise en place comprend un corps central et une pluralité de bras supports flexibles, qui s'étendent de manière radiale et font saillie vers l'extérieur dudit corps central, ces bras servant par ailleurs à soutenir au moins partiellement l'insert. Cet insert repose donc sur l'unité de mise en place fabriquée dans un matériau bioabsorbable, ce qui permet de former une matrice de croissance chondrogénique entre la zone retirée et la zone saine adjacente.
