Official Title: Dynamic Laryngotracheal Separation for Aspiration. Prevention of Silent Aspiration Pneumonia During Swallowing by an Implanted Stimulator

Brief Summary: People who aspirate after neurologic insults such as stroke often develop fatal pneumonia. This study examines the effects of dynamic vocal cord closure on swallowing. Implants placed over the chest wall are connected to electrodes placed around the nerve that closes the vocal cords. The patient triggers closure by flipping the switch of a coil taped over the skin covering the internal stimulator. Vocal cord motion is verified by videotaping through an endoscope, and the status of swallowing is documented radiologically by a modified barium swallow.

Detailed Summary: Data pending
Sponsor: University Hospitals Cleveland Medical Center

Current Primary Outcome: Videotaping vocal cords and modified barium swallows [ Time Frame: several months ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Tolerance of implanted device [ Time Frame: immediate to several years ]
  • comfort in swallowing [ Time Frame: one year ]


Original Secondary Outcome: Tolerance of implanted device [ Time Frame: immediate to several years ]
