  • Publication number: 20140288648
    Abstract: The present invention relates to the field of prosthetics having the function of restoring swallowing, breathing and phonation to a patient having a dysfunctional larynx. More specifically, the present invention concerns a valve device forming an intra-laryngeal endoprosthesis intended for implanting in the anatomical larynx in place having the function of enabling breathing while forming a seal against elements such as saliva, mucus or any other element coming from the bolus. The complete intra-laryngeal endoprosthesis, as well as its various applications, are also the subject matter of the present invention.

  • 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.
