Abstract: The invention relates to an injection needle for injecting a pharmaceutical product into a human or animal body. The needle comprises a tubular body with an end for penetrating into a human or animal body, and having a main bevel and a secondary bevel forming a tip of the needle. The secondary bevel is positioned opposite the main bevel and forms, with the main bevel, a single cutting edge oblique to the longitudinal axis of the tubular body. The cutting edge extends on both sides of a middle plane of the main bevel that passes through the longitudinal axis of the tubular body.

Abstract: A composition of an injectable medicinal product and a gel, concentrating the medicinal product on-site to reinforce its action and/or reduce the toxicity of the medicinal product.

Abstract: A penetrating injection needle for the injection of a pharmaceutical product into a human or animal body. The needle includes a tubular body having two opposing ends, a first end for connection to a device for driving the needle in rotation and pumping a product, and a second end for penetration of the human or animal body and including a main bevel and at least one secondary bevel. The secondary bevel or bevels is/are arranged in opposition relative to the main bevel and form a cutting edge and a needle point with the main bevel.

Abstract: A device for sealing a syringe in which a cartridge is inserted, the cartridge being closed at its top end by a flexible membrane and being connected to an injection needle of a needle-carrier part presenting a crown between the needle and the top surface of the cartridge so as to bear against the membrane to press the membrane inwardly just inside the edge of the orifice in the top surface of the cartridge and sealing the membrane to the top surface along the edge.

Abstract: An injector for medical use, in particular with semisolid substances, the injector comprising a case and at least one injection electric motor pressing against a piston acting on the moving end of a cartridge, the motor being movable in translation inside the body in order to exert force on the axis.

Abstract: A process for devitalization for a tooth in which, after drilling of a small hole through the crown into the pulp cavity, an inert paste is injected under pressure into the pulp cavity and into the root-canal causing a desiccation of the pulp tissues and the devitalization of the tooth.

Abstract: An instrument by which a biocompatible liquid or semi-liquid formulation is injected through bone tissue. The device has a needle (16) removably mounted at the end of a carpule (13). The carpule has a moving base wall, means (4, 8, 9, 12) for rotating the carpule and the needle, and a motor (5) for applying a force to the moving base wall of the carpule. The motor (5) applies the force to the moving base wall via a rack (17) which bears against the moving base wall of the carpule.
