4 results about "Cochlear implantation" patented technology

The present invention relates to the use of azasetron or azasetron analogs, or a pharmaceutically acceptable salt and / or solvate thereof, for the retention of residual hearing after cochlear implant in a subject in need thereof wherein the hearing threshold of at least one ear of the subject at baseline corresponds to an unassisted audiometric threshold of greater than 65 dB at baseline, the unassisted audiometry threshold is represented as an average of at least 3 values measured at each time at different frequencies in the range of 0.25 kHz to 0.75 kHz.

The invention discloses a flexible artificial cochlea electrode material with an inner ear lymph pressure sensing function. The flexible artificial cochlea electrode material comprises an electrode body and a miniature piezoresistive pressure sensor integrated on the electrode body, the micro piezoresistive pressure sensor is arranged at the tip of the electrode body and the back side of the electrode contact array; the miniature piezoresistive pressure sensor comprises a flexible substrate layer, a lower electrode layer, a pressure-sensitive layer, a passivation packaging layer, an upper electrode layer and an overall packaging layer which are arranged in a stacked mode. The miniature piezoresistive pressure sensor is electrically led out through at least three independent metal wires, and the metal wires are connected with a signal processing unit. According to the invention, the hydrostatic pressure of the fluid in the cochlea can be monitored in real time, and a new scheme is provided for guidance in the artificial cochlea implantation and postoperative evaluation.

The application discloses a cochlea flap expander, which comprises an expander assembly, a first supporting piece and a second supporting piece; the expander assembly is provided with an operation end, a first movable end and a second movable end; the first supporting piece and the second supporting piece are connected with the first movable end and the second movable end respectively; the first supporting piece and the second supporting piece can be embedded or separated from each other; the operation end of the expander assembly is provided with an angle keeping assembly, which is used for keeping the distance between the first supporting piece and the second supporting piece. The cochlea flap expander can be adapted to different types of cochlear implantation operations and can replace artificial traction.

The present invention relates to azasetron or an analogue of azasetron or a pharmaceutically acceptable salt and / or solvate thereof for use in preserving residual hearing after cochlear implantation in subjects requiring it, having a baseline hearing threshold corresponding to a baseline unaided hearing threshold of 65 dB or higher in at least one ear (the unaided hearing threshold is expressed as the average of at least three values ​​determined at different frequencies within the range of 0.25 kHz to 0.75 kHz).
