Disclosed are composite implantable tissue attachment devices comprising a mechanical reinforcing component and a cellular scaffold component. Disclosed devices include a wide, relatively flat portion for supporting long term repair of tis-sue. Disclosed devices can include a tapered portion at the end of the wide portions that can lead into a narrower elongated exten-sion for aiding in placement of the device during a surgical procedure. The wide portion of the device can provide tensile strength along the longitudinal axis of the device as well as porosity. The wide devices can cover a larger surface area of a delivery site than standard suture. Disclosed materials can be utilized in, e.g., soft tissue repair such as tendon and ligament reconstruction and repair.
La présente invention concerne des dispositifs de fixation de tissus implantables composites comprenant un composant de renforcement mécanique et un composant déchafaudage cellulaire. Les dispositifs décrits comportent une partie large, relativement plate, formant support dans le cadre dune réparation de tissu sur le long terme. Les dispositifs de linvention peuvent comprendre une partie conique à lextrémité des parties larges, pouvant mener à une extension allongée et plus étroite qui sert à aider à la mise en place du dispositif au cours dune intervention chirurgicale. La partie large du dispositif peut procurer au dispositif une force de traction selon laxe longitudinal dudit dispositif, ainsi quune porosité. Les dispositifs larges permettent de recouvrir une surface plus importante dun site dadministration quune suture standard. Les matériaux décrits peuvent par exemple être utilisés dans le cadre de la réparation de tissus mous, notamment pour la reconstruction et la réparation de tendons ou de ligaments.
