Abstract
Pads for positioning between external hearing prosthesis components and a recipient's skin or scalp that conform to the recipient's anatomy but transmit vibrations from the external components to implanted components. Usable pad materials may include non-Newtonian materials including dilatant materials, rheological materials, memory foams, viscoelastic material, thermoplastics, electro-rheological fluids and or magneto-rheological fluids.
Claims25
A pad for interposition between a recipient's head and a transcutaneous bone conduction device pressure plate, the pad comprising a material providing a controllably variable balance of pressure-equalization and vibration-transmission capability.
A transcutaneous bone conduction system comprising:
- an external component;
- and
- a conformable pad for positioning between a recipient's scalp and the external component, the pad comprising a non-Newtonian material.
A method, comprising:
- causing the viscosity of a material to decrease thereby enabling a pad containing the material to conform to the topographies of a recipient's head;
- and
- causing the viscosity of the material to increase thereby enabling the pad to effectively transfer sound vibrations to the recipient's head.
