Filed:

Mar 13, 2021

Appl. No.:

17/200789

Inventors:

- Staefa, CH
Douglas P. Lynch - Shepherdstown WV, US
Carla Mann Woods - Beverly Hills CA, US
Glen A. Griffith - Newbury Park CA, US

International Classification:

A61N 1/36
H04R 25/00
A61N 1/378
A61N 1/372

Abstract:

An integrated headpiece for a cochlear implant system includes a microphone for outputting an audio signal; signal processing electronics for processing the audio signal; and a transmitter for transmitting a processed audio signal received from the electronics to an implanted receiver. All of the microphone, signal processing electronics, and transmitter are disposed in a common housing of the integrated headpiece. The headpiece may also be one of a set of headpieces that can be alternatively used as needed to suit power consumption requirements or environmental conditions.Cochlear implant systems include a circuit board having electronic circuitry configured to generate one or more signals configured to direct electrical stimulation of one or more stimulation sites within a patient, an induction coil configured to transmit a telemetry signal by generating a telemetry magnetic field, and a telemetry flux guide positioned between the induction coil and the circuit board. The telemetry flux guide is configured to direct magnetic flux of the telemetry magnetic field away from the circuit board.

A61N 1/372

Abstract:

A headpiece for use with a cochlear implant includes a headpiece housing, a microphone within the headpiece housing, an induction coil within the headpiece housing that transmits audio signals to the cochlear implant, signal processing electronics, within the headpiece housing and operably connected to the microphone and to the induction coil, that generate stimulation parameters, and a rechargeable battery operably connected to the induction coil such that the induction coil provides energy to charge the rechargeable battery when the induction coil is inductively coupled to a transmitter coil through which current is passing.

International Classification:

A61N 1/36
A61N 1/378
A61N 1/372
H04R 25/00

Abstract:

A headpiece for use with a cochlear implant including a headpiece housing, a retention magnet within the headpiece housing that generates a retention magnetic field, the retention magnet including a bottom surface that faces the cochlear implant, a top surface opposite the bottom surface, and an outer radial surface between the top and bottom surfaces, an induction coil within the headpiece housing that transmits audio signals to the cochlear implant by generating a telemetry magnetic field, and a retention flux guide within the headpiece housing and adjacent to the top surface of the retention magnet.
