Abstract
A completely in-the-canal hearing device including a conformal tip and a combination vent and retrieval cord is disclosed. The vent and retrieval cord allows pressure equalization between the deep portions of the ear canal and the ambient air. In addition, the vent and retrieval cord allows a user to easily insert and remove the hearing device without the use of auxiliary tools. The vent tube also contributes to the reduction of acoustic feedback.
Claims14
A hearing device, comprising:
- a first module having an external surface;
- a second module removably attached to the first module;
- an elongate tubular body secured along the external surface of the first module and comprising a first lumen, the tubular body having a proximal opening in communication with the first lumen;
- and
- a second lumen extending through the second module, the second module having a distal end opening in communication with the second lumen,
- wherein the tubular body is removably attached to the second module such that the first and second lumens are in communication to thereby form a conduit extending from the proximal tubular body opening to the distal end opening of the second module.

An in-the-canal hearing device, comprising:
- a first module having an external surface and including a microphone;
- a second module including an audio speaker, the second module removably attached to the first module;
- an elongate tubular body secured along the external surface of the first module and removably attached to the second module, the tubular body having a proximal opening and a first lumen in communication with the proximal opening;
- and
- a second lumen extending through the second module, the second module having a distal end opening in communication with the second lumen,
- wherein the first and second lumens are in communication to thereby form a conduit extending from the proximal tubular body opening to the distal end opening of the second module, the conduit providing a pressure equalization vent when the device is positioned within an ear canal.
