  • Patent number: 8551168
    Abstract: The present invention relates to a valve device designed to be implanted in a dysfunctional larynx or in a prosthetic larynx. The valve device has a distal portion forming an annular support structure and a central portion forming an obturator. The obturator includes i) a peripheral part forming a first valve integral with the annular support structure in a first hinge region, and ii) a central part forming a second valve integral with the first valve in a second hinge region.

  • Publication number: 20100023125
    Abstract: An implant being urged to be positioned between the thyroid cartilage (22) and a vocal cord (20) so as to displace the latter in order to restore the speech to a patient, characterized in that it comprises: i) a “prosthesis” (3) being urged to rest on the muscle of the vocal cord (20), ii) a “counterplate” (5) resting on the internal wall of the thyroid cartilage (22), and iii) a liking element (7) of the prosthesis (3) and the counterplate (5), said counterplate (5) being mobile on said at least one linking element (7), thus enabling the adjustment of the distance D between the prosthesis (3) and the counterplate (5) to maintain the implant (1) in place.

  • Patent number: 6410878
    Abstract: The invention concerns a method for producing a flame support for a gas burner, which consists in producing disjointed metal fibres (10) in an alloy comprising iron, chromium and aluminium; assembling the fibres together under pressure; bringing the fibre mat to a temperature sufficient to ensure a close bonding between the fibres. The invention is characterised in that it consists in feeding said metal alloy to an overflowing tank (3), to produce the fibres by cooling in contact with a mobile wheel (7); then in arranging in a moulding matrix the resulting disjointed fibres (10) and compressing them to form an agglomerated mat; then in connecting the mat to electrodes and a capacitor, thereby bringing the fibres (10), at their points of contact, to a temperature not less than their melting point, to produce fibres closely welded together, under high voltage.
