Tool for insertion and removal of in-canal hearing devices
Methods, tools, and methods of manufacturing said tools are provided for inserting a hearing device deeply into the ear canal of a user and adjusting its medial-lateral position therein. The provided tools comprise a shaft. A distal end of the shaft can be coupled to the hearing device. The shaft is flexible to facilitate its insertion into the tortuous ear canal and minimize injurious contact with the ear canal. The length of the shaft can be adjusted to adjust the depth of insertion of the shaft into the ear canal, customizing the tool for an individual user. Medial advancement of the shaft into the ear canal is limited by a base, side extension, or mold coupled to a proximal portion of the shaft or other proximal part of the tool.
1. A tool for adjusting the medial-lateral positioning of a hearing device placed within an ear canal of a user, the tool comprising:
a pressable proximal portion; and
a distal portion, with a profile sized for insertion into the ear canal, including distal tip, the distal tip having an expanded state and an unexpanded state and being configured to capture a lateral end of the hearing device when in the unexpanded state and to release the lateral end of the hearing device when in the expanded state, the proximal portion being coupled to the distal portion such that pressing of the proximal portion expands the distal tip to the expanded state.
2. The tool of claim 1 , wherein the tool has a longitudinal axis and rotating the tool about the longitudinal axis rotates the captured hearing device.
3. The tool of claim 2 , wherein rotating the tool rotates the captured hearing device when the hearing device is captured within the ear canal.
4. The tool of claim 1 , wherein the tool comprises a pair of reverse-action tweezers.
5. The tool of claim 1 , wherein the distal portion comprises a side extension adapted to engage a wall of a conchal bowl of an ear of the user to limit medial advancement of the tool.
6. The tool of claim 5 , wherein the side extension is shaped to conform to the conchal bowl.
7. The tool of claim 1 , wherein the distal portion is flexible.
8. A tool for adjusting the medial-lateral positioning of a hearing device placed within an ear canal of a user, the tool comprising:
a pressable proximal portion;
a distal portion having a profile sized for insertion into the ear canal and a distal tip configured to capture a lateral end of the hearing device; and
means, coupled to the proximal portion and to the distal portion, for causing the distal tip to release a hearing device captured by the distal tip by expanding the distal tip in response to pressing of the proximal portion.
9. The tool of claim 8 , wherein the tool has a longitudinal axis and the distal tip is configured to capture a lateral end of the hearing device such that rotating the tool about the longitudinal axis rotates the captured hearing device.
10. The tool of claim 8 , wherein the distal portion comprises a side extension adapted to engage a wall of a conchal bowl of an ear of the user to limit medial advancement of the tool.
11. The tool of claim 10 , wherein the side extension is shaped to conform to the conchal bowl.
12. The tool of claim 8 , wherein the distal portion is flexible.
