CLOVER SHAPE ATTACHMENT FOR IMPLANTABLE FLOATING MASS TRANSDUCER

摘要

A middle ear prosthesis device is described which includes an elongated prosthesis member having first and second ends. A transducer clamp is at the first end of the prosthesis member with clamping fingers for securely engaging the outer surface of an enclosed mechanical signal transducer. An ossicle fastener is at the second end of the prosthesis member and is adapted for secure attachment to the ossicle of a patient middle ear. The ossicle fastener includes parallel planar fastener clips each having a clover shape with springy lobes surrounding an interior region defined by lobe connecting bends. There is an opening between opposing bent leg ends of each fastener clip that displaceably provides access for the ossicle to the interior region of the clip, so that the fastener clips securely enclose an ossicle such as the incus bone within the interior region.
