20080234817 | 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. | 09-25-2008 |

20160100263 | Active hearing aid implant having adjustable fixation of the actuator end piece in the middle ear - An active hearing aid implant is formed in an arrangement for the adjustment and fixation of the relative position between an axially extended actuator end piece of the hearing aid implant and the surrounding middle-ear bone. Arrangement coupling elements anchor the actuator end piece on the surrounding bone and a sliding ring designed to slide over the cylindrical actuator end piece holds this actuator end piece in a radial direction while the sliding ring remains linearly displaceable in the axial direction of the actuator end piece. Radially protruding coupling elements are fastened radially outwardly on the sliding ring for anchoring the sliding ring on surrounding bone after the arrangement has been surgically inserted into the middle ear. | 04-07-2016 |

20110137109 | IMPLANTABLE MICROPHONE FOR HEARING SYSTEMS - An implantable microphone for use in hearing systems includes a housing having a back wall. The back wall has a recess (e.g., blind hole) configured to be coupled to an auditory ossicle. The implantable microphone also includes a membrane coupled to a top portion of the housing and a vibration sensor adjacent to the membrane. The membrane is configured to move in response to movement from the auditory ossicle, and the vibration sensor is configured to measure the movement of the membrane and to convert the measurement into an electrical signal. | 06-09-2011 |
20110144415 | IMPLANTABLE MICROPHONE FOR HEARING SYSTEMS - An implantable microphone for use in hearing systems includes a housing having a sidewall, a first membrane coupled to a top portion of the housing and configured to move in response to movement from an auditory ossicle, and a second membrane coupled to the sidewall such that an interior volume of the housing is divided into a first volume and a second volume. The second membrane has an opening that permits fluid to flow from the first volume to the second volume. The implantable microphone also includes a vibration sensor adjacent to the second membrane and configured to measure the movement of the second membrane and to convert the measurement into an electrical signal. The vibration sensor may include a piezoelectric sensor and/or a MEMS sensor. | 06-16-2011 |
20120184804 | Insertion System For Inserting Implantable Electrode Carrier - An insertion system for inserting an implantable electrode carrier includes an insertion instrument having a housing with a proximal end and a distal end, and a vibration generator coupled adjacent to the housing. The proximal end is configured to hold the implantable electrode carrier. The vibration generator is configured to generate vibrations in at least a portion of the electrode carrier. | 07-19-2012 |
20120197265 | Instrument for Inserting Implantable Electrode Carrier - A surgical instrument for inserting an implantable electrode carrier includes a housing having a proximal end and a distal end. The proximal end is configured to hold the implantable electrode carrier. The instrument also includes a vibration generator positioned within the housing. The vibration generator is configured to generate vibrations in at least a portion of the electrode carrier. | 08-02-2012 |

20100219961 | LIMIT SIGNAL INDICATOR AND METHOD FOR OPERATING A LIMIT SIGNAL INDICATOR - In a limit signal indicator for determining two positions of a pneumatically operated positioning device, a position sensor detects a position of the positioning device. A first signal transmission contact, a second signal transmission contact, and a microprocessor are provided. The first and the second signal transmission contacts each output a respective electrical limit position signal, the limit position signals representing an adoption of the first and the second positions or of at least one position of the positioning device above or below a predetermined set limit value. At least one of the signal transmission contacts is connected for signal transmission so that in case of a malfunctioning of a signal transmission, the switch amplifier is capable of generating an emergency signal above a maximum limit value or below a lower limit value, and to transmit the emergency signal to an external processing location. The microprocessor, upon detecting a specific operational malfunctioning, actuating the positioning device and executing an emergency procedure according to which the same emergency signal is generated and output at the second signal transmission contact. | 09-02-2010 |
20110247484 | ACTUATING DRIVE FOR POSITIONING A FINAL CONTROL ELEMENT AND METHOD FOR CAPTURING A POSITION OF THE FINAL CONTROL ELEMENT - In an actuating drive or method for capturing a position of a final control element to be positioned by a drive member of the actuating drive, the final control element is pushed from an initial position to a target position by a spring body acting on the drive member. A first reference position is spatially configured in a vicinity of or at the spring body. A second reference position moving relative to the first reference position during positioning movement of the drive member is spatially configured adjacent a first outer surface of the spring body. A distance between the first reference position and the second reference position is captured. | 10-13-2011 |
