Abstract

A hearing aid retention and extraction device comprises a retention ring having an outer bonding surface and an inner grasping surface, and an elongate member extending from the retention ring. The retention and extraction device can be incorporated into a hearing device tip and allows both a hearing device and the hearing device tip to be simultaneously removed from an ear canal. When a user pulls on the elongate member, the retention ring cinches around the hearing device and prevents it from becoming separated from the hearing device tip. The cinching action of the retention ring also holds the hearing device in place within the ear canal.

Claims

1. A device for assisting in the retention and extraction of an in-the-canal hearing device, comprising:

a sheath having a proximal end, a distal end, an outside surface, and an inside surface;

a retention ring having a proximal end, a distal end, an outside surface, and an inside surface, wherein the outside surface of the retention ring is attached to the inside surface of the sheath; and

an elongate member extending from the distal end of the retention ring.

2. The device of claim 1, wherein the sheath is a conformal sheath.

3. The device of claim 1, wherein the sheath is substantially closed at its proximal end.

4. The device of claim 3, wherein an aperture is formed in the proximal end of the sheath.

5. The device of claim 1, wherein the outside surface of the retention ring substantially conforms to contours of the inside surface of the sheath.

6. The device of claim 1, wherein the outside surface of the retention ring has a circumference smaller than a circumference of the inside surface of the sheath.

7. The device of claim 1, wherein the outside surface of the retention ring cinches the inside surface of the sheath.

8. The device of claim 1, wherein the retention ring is formed from a pliable material.

9. The device of claim 1, wherein the retention ring is molded directly into the sheath.

10. The device of claim 1, wherein the elongate member is made of the same material as the retention ring.

11. The device of claim 10, wherein the elongate member and the retention ring form a unitary piece.

12. The device of claim 1, configured such that movement of the elongate member cinches the inside surface of the sheath.

13. The device of claim 1, further comprising a hearing device inserted into the sheath.

14. The device of claim 13, configured such that the hearing device, sheath, retention ring, and elongate member can be simultaneously removed from an ear canal by movement of the elongate member.
