  • Moisture-expandable ear wick
    Patent number: 4159719
    Abstract: A tightly coiled, substantially cylindrical wick of compressed, dehydrated, sponge-like material having sufficient rigidity to be inserted endwise into an ear canal will, when hydrated, uncoil and expand radially whereby to substantially engage the inner surface of the ear canal for applying medicament to said inner surface while securing it against accidental or unintentional dislodgment therefrom. When hydrated, a central opening is provided through the uncoiled member through which opening sound waves may freely pass en route to the ear drum.

  • Method of fabricating a moisture-expandable prosthesis
    Patent number: 4096230
    Abstract: A hollow-cylindrical tube of dehydrated, regenerated cellulose sponge material is tightly compressed to provide an elongate member of minimal diameter having sufficient rigidity to be inserted endwise into a body opening where it will, when moistened, expand radially whereby to substantially engage the inner peripheral walls of the opening for securing it against accidental or unintentional dislodgement therefrom. When used in association with an ear canal an axial opening through the expanded member permits sound waves to reach the ear drum.

  • Moisture-expandable prosthesis
    Patent number: 4034759
    Abstract: A hollow-cylindrical tube of dehydrated, regenerated cellulose sponge material is tightly compressed to provide an elongate member of minimal diameter having sufficient rigidity to be inserted endwise into a body opening where it will, when moistened, expand radially whereby to substantially engage the inner peripheral walls of the opening for securing it against accidental or unintentional dislodgement therefrom. When used in association with an ear canal an axial opening through the expanded member permits sound waves to reach the ear drum. The device can be used to apply medicament by expanding the compressed tube with a liquid medicament.
