The present disclosure provides an implantable fastening device for securing a graft to at least one bone of a joint, comprising a hollow tubular elongate textile element defining an inside volume and including a first free end and a second free end; and a bearing element having at least two through openings. Said elongate element has an initial outside diameter d(mm) and includes an admission orifice leading into its inside volume and an exit orifice going from its inside volume that are spaced apart by an initial distance m(mm) defining a sleeve, the first end of said elongate element being passed into the sleeve so as to form a first loop with at least a portion thereof being passed through at least two through openings of said bearing element. The second free end of said elongate element forms a second loop passing through a through opening of said bearing element. The sleeve receiving a portion of elongate element has an outside diameter at rest n, and the distance mand the outside diameter dof said elongate element are determined in such a manner that in operation, traction exerted on the first free end causes the admission and exit orifices to move towards each other and correspondingly causes the sleeve to expand radially.

Implantable fastening device for securing a graft to at least one bone of a joint

The present invention provides a tensioning ancillary instrument () for tensioning an elongate element to fasten an implant on a portion of bone, by surrounding said portion of bone at least in part, said instrument () comprising a body () having proximal and distal ends (), the distal end () being provided with a device for bearing against the implant, said body () extending along a longitudinal axis (L). The instrument () further comprising a carriage () that is movable along the longitudinal axis (L), and a fastener device () for fastening to the elongate element (). The instrument () also includes a rotary shaft () rotatable about the longitudinal axis (L) of the body (), the shaft () being configured to co-operate with the carriage () in such a manner that rotation of the shaft () drives movement of the carriage () in translation along the longitudinal axis (L) and correspondingly moves the carriage () away from the distal end () of the body () and tensions the elongate element.
