Vocal Cord Patents (Class 623/14.11)
  • Patent number: 9675446
    Abstract: Systems and methods for medializing a paralyzed vocal cord are disclosed. In some embodiments, an apparatus includes a lateral portion, a medial portion, and a strut coupled to the lateral and the medial portions. Either the medial portion or the lateral portion can be adjustable in two dimensions which are not parallel to the length of the strut, which can also be adjustable. In some embodiments, the medial portion and/or the lateral portion can each comprise two adjustable arms and a base member which has a curvilinear configuration.

  • Patent number: 9022024
    Abstract: Methods and devices are disclosed for manipulating the airway, such as to treat obstructive sleep apnea. An implant is positioned within the body with respect to the airway. The spatial orientation of the airway is manipulated, directly or indirectly, to affect the configuration of the airway. In general, the implant is manipulated to displace the trachea in an inferior direction, resist superior displacement of the trachea and/or to alter the tracheal wall tension. The implant restrains the trachea in the manipulated configuration.

  • Publication number: 20140336761
    Abstract: Medical devices, medical device kits, and related methods of treatment are described. An exemplary medical device comprises a proximal portion having an outer surface defining a thread and an inner surface defining a passageway having a keyed portion, a distal portion providing an atraumatic tip, and a flexible main body extending between the proximal portion and the distal portion. The medical device can be positioned in contact with a paralyzed vocal cord to cause a desired medialization for treatment of the vocal cord. The flexible main body allows for deflection upon contact and/or interaction with another device passed into the airway of a treated patient.

  • Patent number: 8721720
    Abstract: A dilator may include a substantially conical body having a tip portion at a proximal end and a base portion at a distal end thereof. A wire lock portion may be configured to lock a guide wire to the dilator. A voice prosthesis holding portion may be connected to the substantially conical body by a connecting portion. The holding portion may have a central passage configured to have a tubular body of a voice prosthesis positioned therethrough, wherein at least one flange of the prosthesis is substantially unfolded proximally of the central passage.

  • Patent number: 7909868
    Abstract: A gel cap is loaded on a folded flange of a voice prosthesis which is loaded on an end portion of an inserter, wherein a tip of the end portion is pressed against a valve flap of the voice prosthesis. The voice prosthesis includes a strap that is stretched for engagement with an attachment portion on the inserter. The voice prosthesis, gel cap, and inserter are inserted into the tracheoesophageal puncture. The patient then swallows fluids to cause the gel cap to dissolve to allow the esophageal flange to deploy, whereby upon deployment of the esophageal flange, the tip of the end portion of the inserter presses the valve flap open, allowing the inserter to move axially relative to the voice prosthesis until a stop collar of the inserter engages the voice prosthesis providing external visual confirmation to the user that the gel cap has dissolved and the esophageal flange has deployed.

  • 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: 7025784
    Abstract: An externally worn tracheal valve has a valve assembly supporting a flexible, resilient lightweight diaphragm centrally thereof. The diaphragm is folded towards the trachea so that air expelled from the trachea will tend to unfold the diaphragm to an extended position to close the valve. During normal breathing the diaphragm remains at least partially folded and the valve remains open. During voice exhalation, the diaphragm extends to close the valve. During high pressure coughing exhalation, the diaphragm may evert, opening the valve to release excessive pressure.

  • Patent number: 6776797
    Abstract: An invention relating to a method for the delivery, or placement, of, for example, a voice prosthesis into a puncture. A flexible flange provided on an outside surface of the device is temporarily resiliently deflected into a delivery orientation so the device can be delivered. Once delivered, the retainer holding the flange in the delivery orientation is removed so the flange can extend out to the use orientation.
