Abstract: The device according to the invention includes a hollow body delimiting an inner passage. It further includes an assembly for maintaining the material in position in the inner passage. The maintaining assembly includes a radially compressible member delimiting, when idle, a through passage aperture of the material, and a radial compression member compressing the compressible member, radially movable relative to an axis of the passage aperture to outwardly compress the compressible member. It includes a member for actuating the or each compression member, radially movable relative to the body to cause the compression member to go from a radially retracted position, in which the section of the passage aperture is maximal, to a position radially deployed in the compressible member, in which the section of the passage aperture is minimal.

Abstract: The needle protection device comprises: a protector support (20), defining an introduction duct for a syringe body, a needle protector (22) which may be displaced relative to the protector support (20), between a retracted position and a deployed position, a compression spring (24), applied between the protector support (20) and the needle protector (22) and initial retaining means (38, 40, 54) for the needle protector (22) against the force of the compressed spring (24), said means (38, 40, 54) being released by displacement of the needle protector (22) in a release direction with relation to the protector support (20). The device further comprises mechanical locking means (56) for the needle protector (22) with relation to the protector support (20) in the release direction in the absence of a syringe body in the protector support duct and said mechanical locking means (56) may be deactivated by engaging a syringe body in the duct on the protector support (20).

Abstract: The inventive needle protective device (2) comprises a protective support (20), a movable needle protector (22), a compression spring (24) applied between the protective support (20) and the needle protector (22) and means (38, 40, 54) for initially holding the needle protector (22) oppositely to the compression spring (24) action, wherein said means (38, 40, 54) are releasable by the needle protector (22) displacement in a releasing direction with respect to the protective support (20). Said device also comprises mechanical means (45, 62) for locking the needle protector (22) actuatable by the action of a needle protective cap engaged into the end opening (60) of the needle protector (22) and deactivatable by the cap releasing.

Abstract: A cartridge for folding an ophthalmic implant including pliers having two articulated arms which are provided with substantially coaxial channels and each of which is boarded by two longitudinal edges. The channels are open in front of each other and define a partially folded conduit containing the implant when the two arms are brought to each other. When the two arms are brought to each other, at least two edges positioned in front of the channels are driven apart transversally with respect to a conduit on a plane. The two arms are jointed in such a way that the arm delimits the supporting shoulder of the implant being projected in front of the channel embodied in the other arm.

Abstract: The invention relates to an injection device, comprising an injection syringe (1) with a tubular syringe body, provided at a porximal end with a fixing collar (16), projecting radially outwards, an injection piston, arranged to slide within the body, a needle protection device (2), comprising a protector support (20) and a sliding needle protector (22). The device comprises a stop pin (25) for the piston stop (8), said pin (25) is mounted on the protector support (20) and defines, in the extension of the syringe body, a piston circulation passage of which the minimum section is larger than the section of the running part (10) of the piston and less than the section of a shoulder (15) of the piston.

Abstract: A needle-protection device (2) for a syringe (1) having a needle (6), a tubular body (4) and an injection plunger (8). The device includes: a needle protector (22); a protector support (20); a spring (24) which presses against the support (20) and the protector (22), the support and protector being movable relative to one another between a retracted protector position, in which the needle of the syringe is exposed and the spring is locked in compression, and a deployed protector position in which the needle is disposed inside the protector and the spring is at least partially decompressed; and a mechanism for unlocking the spring. When locked, the spring (24) exhibits a predetermined force which is greater than the push force required to move the plunger (8) along essentially all of the injection stroke thereof.
