  • Patent number: 5494029
    Abstract: A laryngeal stent for supporting anatomical features of the mammalian larynx, including a human larynx is formed by a gas-inflatable envelope fabricated from a resilient, deformable material can conform to the anatomical surfaces of the larynx within the mammal's esophagus when pressurized by the gas. In preferred embodiment stents, the surface of the envelope is coarse, allowing for the venting of air between the laryngeal surfaces and the envelope. However, the stent conforms so closely to the anatomical features of the larynx that sutures are not required to anchor the stent in place.

  • Patent number: 5048518
    Abstract: A stoma stent system for treating patients after tracheostomy and maintenance of a tracheastomy tract includes a tubular stent for insertion in the trachea and several plug components which may be inserted into the open, free end of the stent for several functions. For example, a plug may have several inserts for progressively constricting air flow through the stent to wean the patient off the stent. The same, or another plug may include a vapor source for transferring moisture from exhaled air to inhaled air. A third plug may include a check valve which blocks exhaled air and redirects the air toward the vocal cords to permit the patient to speak and cough.
