A device made up of a textile tubular sheath, which can be implanted in the human body, suitable for containing a filling material and the ends of which are suitable for covering the ends of two portions of a single resected rib. The sheath contains a braid, in which the yarns allow relative movement in relation to one another in order locally to modify the diameter and the shape of the braid, such that the braid not only covers but also encloses the end of one portion of the rib. The sheath is secured to a tip which, allowing the injection of a biocompatible material for filling the sheath, the packing of the braid and the connection by adhesion of the sheath and the braid with the ends of the portions of the rib, is in turn sectional. |

1. A device for osteosynthesis of the thoracic wall, comprising:
a textile tubular sheath which can be implanted in the human body and is able to contain a filling material, the textile tubular sheath having deformable corrugations at a first end and at a second end that are integrally formed with one or more portions without corrugations between the first and second ends, such that the deformable corrugations form a single, unitary body with the one or more portions without corrugations between the first and second ends, the first and second ends being able to envelop, respectively, a first end and a second end of a resected rib, a braid having a first end and a second end, the braid being disposed inside of the sheath and being constructed of biocompatible yarns, which are made of metal or polymer, the biocompatible yarns being configured to allow relative movements in relation to one another in order to locally modify an external diameter and a shape of the braid, such that each end of the braid not only is able to envelop but also is able to tightly hold each end of the resected rib, respectively, wherein the braid has, before implantation, an external diameter equal to an internal diameter that the sheath has before implantation, and wherein the deformable corrugations of the sheath are movable in a first direction to cover the entire braid when the braid envelops the first end and the second end of the resected rib to thereby secure the braid to the resected rib, and wherein the sheath is movable in a second direction, which is opposite of the first direction, to uncover the braid so that the braid is able to engage the first end and the second end of the resected rib; and a nozzle for injection of a biocompatible material, wherein the nozzle is both (i) integrally connected to the textile tubular sheath and (ii) removable from the textile tubular sheath, penetrating the braid and adhesively bonding the first and second ends of the sheath and of the braid to the first and second ends of the resected rib, respectively. |
