36 results about "Ossicles" patented technology

The ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body. They serve to transmit sounds from the air to the fluid-filled labyrinth (cochlea). The absence of the auditory ossicles would constitute a moderate-to-severe hearing loss. The term "ossicle" literally means "tiny bone". Though the term may refer to any small bone throughout the body, it typically refers to the malleus, incus, and stapes (hammer, anvil, and stirrup) of the middle ear.

Implantable middle ear hearing device having tubular vibration transducer to drive round window

An implantable middle ear hearing device having a tubular vibration transducer to drive a round window is designed to input sound to a round window opposite an oval window in an inner ear. The tubular vibration transducer has a unique structure that does not attenuate the magnitude of a signal, particularly, in a high frequency band. Sound delivery effect is much higher than those of conventional schemes. It is also possible to minimize difficulties associated with and problems resulting from the operation, which the conventional methods would have. Further, the transducer can have a relatively less compact than ossicle contact type transducers, and thus be easily fabricated. The hearing device can be applied to a sensorineural hearing loss patient with the ossicle damaged. Moreover, since sound is directly transmitted without through the ear drum and the ossicle, high efficiency sound delivery is achievable and hearing loss compensation are easy.

Ossicle prosthesis with sensitive top plate

An ossicle prosthesis includes, at one end, a first fastening element designed as a top plate for mechanical connection with the tympanic membrane, and, at the other end, a second fastening element for mechanical connection with a component or parts of a component of the ossicular chain or with the inner ear, and a connecting element that connects the two fastening elements with each other in a sound-conducting manner; the top plate includes a radially outward annular region, a radially inward attachment region for mechanically attaching the top plate to the connecting element, and several segment elements for radially connecting the annular region with the attachment region, characterized by the fact that the segment elements are geometrically designed such that they locally emulate any localized medial motions made by the tympanic membrane, but they do not transmit the motion to distant regions of the top plate. As a result, a high level of post-operative flexibility and variability of the prosthesis, and higher-quality sound conduction through the prosthesis may be attained in a technically simple, uncomplicated, and cost-favorable manner.

Ossicular Prostheses Fabricated From Shape Memory Polymers

Ossicular replacement prostheses are manufactured from a non-biodegradable shape memory polymer. Such prostheses can include TORPs, PORPs, and incudo-stapedial joints (ISJs). The prostheses are reshaped upon application of a stimulus to capture a portion of one or more ossicles. The force of capture of a reshaped polymeric prosthesis is less than a comparable reshaped shape memory alloy prosthesis and thereby prevents recipient discomfort and / or pressure induced necrosis of the bone. In addition, biocompatible shape memory polymers can be designed with recoverable strain that is orders of magnitude higher than shape memory alloys. Furthermore, prostheses can be manufactured in a single size and easily trimmed or otherwise modified by the surgeon during the implantation procedure to tailor the prosthesis in size and / or shape for the particular anatomy. Such modification does not negatively effect the ability of the prostheses to engage the ossicle.
