An example implant system to treat glottic insufficiency is disclosed. The implant system includes a fixation frame including a first set of flanges at a first edge of the fixation frame and a second flange at a second edge of the fixation frame, wherein the fixation frame is configured to secure the implant system at an opening of the patient's thyroid cartilage, a port system disposed in the fixation frame and configured to receive, deliver, maintain, or remove a filler, and a flexible member, coupled to the fixation frame and in fluid or air communication with the port system, wherein based on an amount of the filler in the flexible member, the flexible member is configured to inflate in a direction to push against the patient's arytenoid cartilage so the arytenoid cartilage is rocked, adducted and/or rotated inferomedially.

Methods and apparatus for treating glottic insufficiency

An implant system for treating glottic insufficiency includes an implant, which includes a balloon with a port connector or a catheter and a band comprising a proximate end attached to a portion of the balloon that translates away from the port connector or the catheter when the balloon is inflated through the port connector or the catheter.

A method to treat glottic insufficiency includes creating a window in a thyroid cartilage and inserting an implant through the window and into a paraglottic space. The implant includes a balloon with a port connector and a band comprising a proximate end attached to a portion of the balloon. The method further includes securing the band to a thyroarytenoid muscle complex and inflating the balloon to pull on the band, which in turn pulls on the thyroarytenoid muscle, which in turn rotates an arytenoids cartilage to medialize and tighten a vocal cord.
