Various embodiments of the present invention relate to compositions for delivering bone growth inducing material (e.g., to viable bone and/or other skeletal tissues to repair defects and the like). More particularly, various embodiments of the present invention relate to delivery mechanisms for an osteotherapeutic material (e.g., osteoinductive and/or osteoconductive materials), including (but not limited to) demineralized bone matrix ("DBM") and cortical-cancellous bone chips ("CCC"). Certain compositions according to various embodiments of the present invention may comprise mixtures of a physiologically acceptable biodegradable carrier, an osteoinductive material, and/or an osteoconductive material (e.g., DBM and CCC). The compositions may thus be applied (for example, to defective bone tissue and/or other viable tissue) to induce formation of new bone. Other embodiments of the present invention relate to the preparation of compositions and methods of using such compositions.

Dans différents modes de réalisation, la présente invention concerne des compositions destinées à la délivrance d'un matériau induisant la croissance osseuse (p.ex., des tissus osseux viables et/ou autres tissus squelettiques destinés à la réparation de défauts et analogue). En particulier, différents modes de réalisation de l'invention concernent des mécanismes de délivrance d'un matériau ostéothérapeutique (p.ex., des matériaux ostéoinducteurs et/ou ostéoconducteurs), y compris (mais de manière non limitative) une matrice osseuse ostéoinductrice ("DBM") et des copeaux d'os cortical spongieux ("CCC"). Certaines compositions selon divers modes de réalisation de l'invention peuvent comprendre des mélanges d'un véhicule biodégradable physiologiquement acceptable, d'un matériau ostéoinducteur et/ou d'un matériau ostéoconducteur (p.ex., DBM et CCC). Les compositions précitées peuvent par conséquent être appliquées (par exemple, sur des tissus osseux défaillants et/ou d'autres tissus viables) afin d'induire la formation d'un os nouveau. D'autres modes de réalisation de l'invention se rapportent à la préparation des compositions et à des procédés d'utilisation desdites compositions.
