Abstract
The application discloses a Tympanic Membrane Implant used for equalizing pressure and allowing drainage in patients who have fluid build-up and pressure in the middle ear. The Tympanic Membrane Implant is a rigid tube, having flanges at a critical angle to one end of the tube and a tapered portion at said end of the tube for easy surgical insertion. It can contain rigid flanges at the opposite end. The invention overcomes the problem of difficulty of insertion, an inability to retrieve rigid tubes when it is desired, and the propensity of rigid tubes to be easily rejected by the body. It also overcomes the damaging effect and production of scars by the implant on the tympanic membrane.
