  • Patent number: 11229726
    Abstract: In some embodiments, the present invention provides methods for making resorbable ear tubes including the steps of providing a silk fibroin solution, and forming a silk ear tube from the silk fibroin solution, wherein the silk ear tube is less than 2 mm in length and has an outer diameter of less than 1.5 mm, and wherein the silk ear tube is resorbable. In some embodiments, the present invention also provides methods for treating otitis media including the step of introducing a silk ear tube into the ear canal of a subject, wherein the silk ear tube is less than 2 mm in length and has an outer diameter of less than 1.5 mm, and wherein the silk ear tube is resorbed by the subject.

  • Publication number: 20200054796
    Abstract: Bioresorbable silk fibroin tracheal stents can be designed and engineered to maintain a tracheal opening. A tracheal stent will maintain a tracheal opening for a period while tissue structure and function is restored. Bioresorbable silk fibroin tracheal stents programmably degrade without negative biological or clinical outcomes. Bioresorbable silk fibroin tracheal stents do not need to be removed following tracheal restoration. Bioresorbable biopolymer tracheal stents can be internally or externally deployed. Bioresorbable biopolymer tracheal stents, for example can be internally or externally deployed in a patient. Such stents may be affixed to function as a splint with tunable mechanically properties to treat, for example, a patient with severe airway collapse.
