MIDDLE-EAR PROSTHESIS The invention relates to a medical prosthesis. This is a middle-ear prosthesis (16) provided with a means (23) of fastening to the tympanic frame (24), a flexible suspension means (22), and a means of transmitting sound between the tympanic membrane (3) and the oval window, the transmission means comprising an arm (17) representing the malleus (4) and connected to a second arm (19) representing the incus (6) and connected to the stapes (8) or to a columella (21) representing it. The suspension to the tympanic frame (24) ensures better compliance and the independent articulation to the tympanic membrane (3), on the one hand, and to the base (10) of the stapes (8), on the other hand, effects a diminution of impedance, thus giving better transmission of sound between the external ear and the inner ear. |
