Abstract: The invention relates to a device for the injection of a bone cement. The invention comprises a container provided with one end including an outlet and a second end that receives a piston. The piston is moved by means of an injection screw that projects from the container body and engages with gripping means comprising injection screw rotation means that can self-lock depending on the pressure exerted inside the container body, said rotation means comprising a handle which is provided with a passage that receives the injection screw and which is hinged thereto by means of a pair of male/female disks. One disk is known as the drive disk and moves integrally with the rotation movements of the handle, while the other disk is known as the driven disk, said drive disk coming into contact with the driven disk in response to a compressive force exerted on the distal part of the injection screw.

Abstract: Embodiments of the present disclosure are directed to devices, systems and methods for delivering viscous materials into a body, and more particularly, to devices, systems and methods for delivering bone fill material, biomaterials, and/or other flowable compounds into vertebrae, during, for example, a vertebroplasty procedure.

Abstract: The present invention relates to a device for the replacement of a permanent articular prosthesis at an implant site, comprising a stem (1) suited to being fixed to a support bone, connected to a head (2) suited to being arranged in an articular area, comprising at least two different cavities (3) with leak tight walls formed at the head (2) made of a thermoplastic material, said cavities (3) emerging at the surface of the device in contact with the implant site, and means for separating (4) cavities (3) from the implant site, enabling the diffusion of a liquid on either side of said separating means.
