  • Publication number: 20110022055
    Abstract: The injector for injecting a flexible intraocular implant comprises: a channel having a main portion of diameter D1, an open end portion of diameter D2 (with D2<D1), and a transition portion; a rigid piston movable along the channel to push the folded implant in the channel, and a substantially circularly symmetrical thrust part made of a material that is hydrophobic and elastically deformable, said thrust part having an outside diameter D3 not less than D1, said part being placed in said channel between the folded implant and the end of said piston without being mechanically connected to said piston. When the implant is pushed in the channel by the piston, said thrust part can deform elastically to penetrate in part into the end portion of the channel, thereby expelling the implant from the channel, and remaining jammed in said end portion of the channel when the piston is withdrawn.

  • Patent number: 7229449
    Abstract: The invention relates to a folding device for folding intraocular implants having flexible optical portions. Said device comprises two folding element facing each other and whose ends are connected together by deformable means. Each folding element comprises a body and a jaw projecting from said body, an elastically deformable support projecting from said body in the direction in which the two elements are brought together, a positioning stud projecting from said second end of the support perpendicularly to said support and facing upwards so as to co-operate, at rest, with the periphery of the optical portion of the implant, and an extension projecting from said body in the direction in which the two elements are brought together, and having a ramp suitable for co-operating with the support on the other folding element while the two folding elements are being brought together to cause said positioning stud to be lowered.

  • Patent number: 7226455
    Abstract: The invention relates to a folder module for folding a flexible intraocular implant for injection into the eye of a patient. The module comprises two jaws that are movable relative to each other, each jaw having a folder wall constituted by a portion of a cylindrical surface, and a plane wall secured to the folder wall, the two plane walls lying in parallel planes; a pivot axis orthogonal to the plane walls to control relative pivoting movement of one jaw relative to the other; one of the jaws being capable of occupying relative to the other a first position in which said plane walls are offset relative to each other; a second position in which the plane walls face each other so as to define an implant confinement volume; and a third position in which the folder walls meet each other to define a folder chamber enabling the implant to be finally folded.

  • Patent number: 6926744
    Abstract: The invention relates to an intraocular implant comprising an optical portion presenting an anterior optical surface (24) and a posterior optical surface (26), and at least one haptic element (12, 14), each haptic element presenting a connection zone at the periphery of the optical portion. Outside the connection zones, the optical portion further comprises a cylindrical side face of diameter D1 connected to the posterior optical surface of the optical portion. The posterior optical surface (26) is bounded by a circle of diameter D1. In each connection zone, the implant comprises a radial extension (30) presenting an anterior face (30a), a posterior face (30b), and a side face (30c) substantially disposed on a ruled surface of diameter D2 where D2>D1, and presenting a length h? in the direction of the axis, said length h? being substantially equal to h. The posterior face (30b) of each extension is disposed on the spherical cap containing the posterior optical surface.

  • Patent number: 6749631
    Abstract: The invention relates to a ring (10) for a capsular bag, the ring being constituted by a curved elongate element presenting substantially constant thickness and having inner and outer edges. The elongate element comprises a first branch (30) extending between a first end (20) and a point B, and a second branch (32) extending between said point B and a second end (22), said outer edge of the elongate element when at rest and in its plane of symmetry being disposed substantially tangentially at a point A to a circle of center O and of radius R not less than the radius of the capsular bag, the outer edge of said first branch being defined by a portion of a circle of center O′ and of radius R′, where R<R′<1.10R, the outer edge of the second branch of said elongate element being defined by a portion of a hyperbolic spiral of center O and connected tangentially to said portion of a circle at said point B.

  • Patent number: 6685963
    Abstract: Biocompatible diphasic compositions are prepared comprising a dispersed phase suspended in a continuous phase, more particularly suitable for use as a filling material in reparative and plastic surgery. The dispersed phase consists of particles of at least one hydrogel of a (co)polymer obtained by polymerizing and cross-linking acrylic acid, methacrylic acid and/or at least one derivative of said acids. The continuous phase is an aqueous solution or hydrogel of a polymer selected from proteins, polysaccharides and their derivatives which have been cross-linked. The polysaccharide may be hyaluronic acid, its salts and a mixture of its salts, advantageously consisting of a sodium hyaluronate.
