Definitions
- the present disclosure relates to apparatuses for controlling and/or positioning devices into a living body, specifically apparatuses for controlling and positioning ear canal components in an ear canal.
- Hearing aids are used to assist a person who has impaired hearing or does not perceive sound properly. Technological advances in hearing aids have reduced their size. Accordingly, many components of the hearing aid are very small making the manipulation and positioning of components within an ear canal difficult.
- RITE receiver-in-the-ear
- RIC receiver-in-the-canal
- RITA receiver-in-the-aid
- the ear canal component can include a sound receiver, a tip (e.g. occluding ear dome, non-occluding ear dome, other suitable component) portions of a wire, portions of an acoustical mini sound tube, and/or other hearing air components that are positioned in the ear canal.
- the receiver and/or the tip are positioned in the ear canal and a thin wire connects the receiver and/or the tip to the main body of the hearing aid.
- a tip (and generally a portion of the acoustical mini sound tube) is positioned in the ear canal, and the tip is connected to the main body of the hearing aid by the acoustical mini sound tube.
- the receiver is located in the main body of the hearing aid.
- Certain examples of hearing aids or ear canal components include a retention tail that maintains the ear canal component in the correct position in the ear canal and/or increases the stability of the ear canal component in the ear canal.
- Maintaining the ear canal component in position in the ear canal is important as movement of the ear canal (due to the user talking, chewing, leaning over, turning of the head, and/or walking) can cause the ear canal to change shape, and therefore, result in slippage of the ear canal component which may change the performance of the hearing aid.
- ear canal component be property inserted and positioned in the ear canal.
- the ear canal component must be seated correctly to ensure that the hearing aid user is receiving the prescribed amplification and the hearing aid is secure.
- a fingertip and/or fingernail to position the ear canal component can result in user frustration, inability to manipulate the ear canal component, and/or too much effort by the user due to the lack of an adequate surface area and accommodations for a fingertip and/or fingernail to manipulate and position the ear canal component.
- the small size of the ear canal component makes it very difficult for the user to manipulate and control the orientation and position of the hearing aid component as the user attempts to direct the ear canal component through the angled and sloped pathways of the ear canal. For instance, a user may have several angles, bends, or curves in the ear canal. Furthermore still, dexterity or mobility limitations of older hearing aid users make the ability to manipulate and position the ear canal component even more difficult and frustrating.
- the ear canal component also lacks adequate surface area for a fingertip to manipulate the movement of the ear canal component. For instance, fingertip may slide past and alongside the ear canal component making manipulation of the ear canal component nearly impossible.
- the hearing aid such as the ear canal components, the connector wire, and acoustical mini sound tube, are often very delicate. Substantial force on any component may cause damage, malfunction, and/or destruction of the hearing aid. Often times, a twisting motion is used by a user to attempt to achieve proper positioning, but this twisting motion can cause substantial damage to the hearing aid component.
- Example prior attempts at solving the problems discussed above have been disclosed in U.S. Patent Publication Nos. 2009/0285428 , 2009/0082801 and 2006/0215862 .
- all disclosures have their own problems. It is also conceivable that these handheld tools may cause injury to the user if improperly inserted into the ear canal. For instance, inserting a tool too deeply into the ear canal may rupture to the tympanic membrane (ear drum) and/or injure the surface of the ear canal. Also, the user may lose the handheld tool.
- an apparatus for controlling and positioning a device in a body cavity includes a cap configured to couple to the device such that the cap increases maneuverability of the device in the body cavity as the device is positioned in the ear canal.
- an apparatus for controlling and positioning of ear canal components in an ear canal comprising a cap with a first end portion configured to couple with the ear canal component such that the cap increases maneuverability of the ear canal component in the ear canal as the ear canal component is positioned in the ear canal.
- the cap including a gripping structure at a second end portion of the cap located opposite to said first end portion, wherein gripping structure projects in a direction away from the first end portion of the cap; and a projection at the second end portion of the cap, wherein the projection projects in a direction away from the first end portion of the cap.
- the gripping structures and the projection define a groove with a contact surface between them, wherein the groove is adapted to receive a fingernail.
- an assembly comprising an ear canal component of a hearing aid that is positionable in an ear canal and an apparatus for controlling and positioning the ear canal component in the ear canal.
- the apparatus comprising a cap for increasing maneuverability of the ear canal component in an ear canal.
- the cap including a gripping structure at a second end portion of the cap located opposite to said first end portion, wherein gripping structure projects in a direction away from the first end portion of the cap; and a projection at the second end portion of the cap, wherein the projection projects in a direction away from the first end portion of the cap.
- the gripping structures and the projection define a groove with a contact surface between them, wherein the groove is adapted to receive a fingernail.
- the cap is configured to increase maneuverability and control of the ear canal component as the ear canal component is positioned in the ear canal.
- the terms “include” and “including” have the same meaning as the terms “comprise” and “comprising” in that these latter terms are “open” transitional terms that do not limit claims only to the recited elements succeeding these transitional terms.
- the term “consisting of,” while encompassed by the term “comprising,” should be interpreted as a “closed” transitional term that limits claims only to the recited elements succeeding this transitional term.
- the term “consisting essentially of,” while encompassed by the term “comprising,” should be interpreted as a “partially closed” transitional term which permits additional elements succeeding this transitional term, but only if those additional elements do not materially affect the basic and novel characteristics of the claim.
- a hearing aid includes an apparatus that allows a user to control and position an ear canal component of the hearing aid into an ear canal. More specifically, the apparatus is an ergonomically designed fingertip fitting guide that couples to the ear canal component to increase the control of the ear canal component while the user positions the ear canal component into the ear canal. The apparatus can prevent damage to the hearing aid (such as the ear canal component) and/or sensitive ear structures.
- fingertip and/or “fingernail” in this disclosure does not limit the scope of the present disclosure to the specific body part referred to.
- a fingertip, fingernail, and/or another part of a human extremity can be used to contact, position, and manipulate the apparatus described herein.
- the application of the present disclosure discussed herein does not limit the scope of the present disclosure and the example application to an ear and/or ear canal is used herein for purposes of context such that it will be recognized by those of ordinary skill that other applications (e.g. nasal cavity, vaginal cavity, anal cavity) and/or uses of the present disclosure may find similar advantages for devices or items (e.g. suppositories) that are positioned in other body cavities.
- the embodiments set forth herein are merely examples and not intended to be limiting.

- the apparatus 26 may be integral with the ear canal component 23 (e.g. the apparatus 26 can be integral with a molded plastic cover of the receiver; the apparatus 26 can be integral with the dome of the hearing aid; the apparatus 26 can be integral with the ear canal component 32).
- the apparatus 26 can be made of any suitable material such as elastic materials, rubber, silicon, flexible plastic, rigid plastic, ceramic, metal, and/or the like.
- the cap 28 includes a gripping structure 33 that projects outwardly from the contact surface 29 of the cap 28. Any number of gripping structures 33 can be included with the cap 28.
- the gripping structures 33 can be any suitable size and/or shape (e.g. rectangular, circular, triangular, concave). In certain examples, the gripping structures 33 are truncated (see FIGURE 4 ).

- the size and/or shape of the connector hole 40 can vary based on the dimensions of the ear canal component 23 (e.g. the connector hole 40 is circular or oval in shape). In certain examples, the diameter of the connector hole 40 is equal to the diameter of the connector 22.
- the connector hole 40 can be located in the center of the cap 28 on a center axis (not shown). In other examples, the connector hole 40 is radially offset from the center of the cap 28.
- the cap slit 41 intersects the connector hole 40 and the outer edge 80 of the cap 28.
- the cap 28 is configured to elastically deform as the cap 28 couples to the ear canal component 23 such that the cap slit 41 opens whereby the user can position the connector 22 into the connector hole 40.
- the cap slit 41 returns to a closed position such that the connector 22 is not easily moved from the connector hole 40 without an appropriate force and/or the apparatus 26 is not easily removed from the connector 22 and/or the ear canal component 23. In a closed position, two surfaces of the cap slit 41 can contact each other.
- the cap slit 41 is a cut in the cap 28 between the connector hole 40 and the outer edge 80 that defines two surfaces that abut each other in the closed position and separate from each other in an open position. In other examples, a space or gap may separate the two surfaces of the cap slit 41.
- the apparatus 26 includes a sidewall 48 coupled to the cap 28.

- the sidewall 48 elastically deforms as the user stretches the sidewall 48 around the ear canal component 23.
- the sidewall 48 can be any size and/or shape.
- the sidewall 48 is annular.
- the sidewall 48 can be made of any suitable material such as elastic materials, rubber, silicon, flexible plastic, rigid plastic, ceramic, metal, and/or the like.
- the sidewall 48 can be made from the same material of the cap 28 or made from a different material.
- the sidewall 48 can include a plurality of fins or ribs 55 that project into the cavity 49 and are configured to deform as the cavity 49 receives the ear canal component 23 such that the ribs 55 couple to and/or engage with the ear canal component 23.
- the ribs 55 are integrally coupled to the sidewall 48 and are made of any suitable material.
- the structure e.g. projections, detents, suction cups, textured pads
- size, and/or the shape of the ribs 55 can vary.
- the ribs 55 depicted in FIGURES 10A and 10B are smaller and have a different shape when compared to the ribs 55 depicted in FIGURES 11A and 11B .
- the ribs 55 can be stepped in height and/or width such that the rib height and/or width increases from an open end 51 of the cavity 49 to the closed end 50 of the cavity 49 such that engagement or coupling between the ribs 55 and the ear canal component 23 increases as the ear canal component 23 is inserted further into the cavity 49.
- the ribs 55 are depicted in an erect or undeformed position.
- the ribs 55 are depicted in a collapsed or deformed position such as when the ear canal component 23 is received by the cavity 49.
- the ribs 55 deform, collapse, are received in pockets (not shown), and/or move relative each other while moving from the undeformed position to the deformed position.
- the ribs 55 fold onto or overlap adjacent ribs 55.
- the ribs 55 fold or collapse into pockets (not shown).
- the ribs 55 are configured to accommodate ear canal components 23 having different shapes and sizes (i.e. a single apparatus 26 having the sidewall 48 with the ribs 55 accommodates several different ear canal components 23 manufactured by different hearing aid manufacturers). Often, hearing aid manufacturers manufacture various hearing aids 20 with different attributes (e.g. size, dimensions, shapes).
- the sidewall 48 includes an outer surface 57 that defines sidewall channels or slots 58.
- the sidewall channels 58 are opposite the ribs 55 relative to the sidewall 48.
- the sidewall channels 58 receive and/or mate with fingers 74 of a retention tail 70 (to be described below).
- the sidewall 48 is flush with cap 28 such that there is no edge or surface between the sidewall 48 and the cap 28 (see FIGURES 6A-6H ).
- the cap 28 includes a lower surface 38 positioned between the cap 28 and the sidewall 48 such that the sidewall 48 is inset from the outer edge 80 of the cap 28 (see FIGURES 7A-7C , 8A-8C , and 9A-9C ).
- the sidewall 48 includes a top surface 60 adjacent to the cap 28.
- the sidewall 48 includes a sidewall slit 56 that aligns with the cap slit 41 (see FIGURES 6C , 7C , and 9C ).
- the sidewall slit 56 opens as the user elastically deforms the sidewall 48 to position the ear canal component 23 in the cavity 49.
- the sidewall slit 56 returns to a closed position such that the ear canal component 23 is not easily moved from the apparatus 26 without an appropriate force.
- two opposite surfaces of the sidewall slit 56 can contact each other.
- a space or gap may separate the two edges of the sidewall slit 56.

Description
- The present application claims priority to
U.S. Provisional Application No. 62/204,043 filed on August 12, 2015 U.S. Provisional Application No. 62/289,433 filed on February 1, 2016 U.S. Patent Application No. 15/225,010 filed on August 1, 2016 - The present disclosure relates to apparatuses for controlling and/or positioning devices into a living body, specifically apparatuses for controlling and positioning ear canal components in an ear canal.
- Hearing aids are used to assist a person who has impaired hearing or does not perceive sound properly. Technological advances in hearing aids have reduced their size. Accordingly, many components of the hearing aid are very small making the manipulation and positioning of components within an ear canal difficult.
- Generally, there are two types of behind-the-ear hearing aids. Those with receiver-in-the-ear (RITE) (also sometimes called receiver-in-the-canal (RIC)), and those with the receiver-in-the-aid (RITA). Both the RITE and certain RITA hearing aids require a small ear canal component be positioned in the ear canal of the user. The ear canal component can include a sound receiver, a tip (e.g. occluding ear dome, non-occluding ear dome, other suitable component) portions of a wire, portions of an acoustical mini sound tube, and/or other hearing air components that are positioned in the ear canal. In the example of a RITE hearing aid, the receiver and/or the tip are positioned in the ear canal and a thin wire connects the receiver and/or the tip to the main body of the hearing aid. In the example of a RITA hearing aid, a tip (and generally a portion of the acoustical mini sound tube) is positioned in the ear canal, and the tip is connected to the main body of the hearing aid by the acoustical mini sound tube. In this case, the receiver is located in the main body of the hearing aid. Certain examples of hearing aids or ear canal components include a retention tail that maintains the ear canal component in the correct position in the ear canal and/or increases the stability of the ear canal component in the ear canal. Maintaining the ear canal component in position in the ear canal is important as movement of the ear canal (due to the user talking, chewing, leaning over, turning of the head, and/or walking) can cause the ear canal to change shape, and therefore, result in slippage of the ear canal component which may change the performance of the hearing aid.
- Regardless of whether a RITE or RITA hearing aid is utilized by a user, it is essential that ear canal component be property inserted and positioned in the ear canal. The ear canal component must be seated correctly to ensure that the hearing aid user is receiving the prescribed amplification and the hearing aid is secure.
- Presently, it can be very difficult for hearing aid users to insert, control, position, and seat the ear canal component of a hearing aid sufficiently deep into the ear canal for a variety of reasons. Attempts have been made to make the process of positioning the ear canal component using a variety of devices including tweezers, holding rods, and insertion tools. However, hearing aid users intuitively use their fingertips to push the ear canal component into place in the ear canal. The use of a fingernail also can further assist the user when pushing the ear canal component into place in the ear canal. Often times however, the use of a fingertip and/or fingernail to position the ear canal component can result in user frustration, inability to manipulate the ear canal component, and/or too much effort by the user due to the lack of an adequate surface area and accommodations for a fingertip and/or fingernail to manipulate and position the ear canal component.
- Furthermore, the small size of the ear canal component makes it very difficult for the user to manipulate and control the orientation and position of the hearing aid component as the user attempts to direct the ear canal component through the angled and sloped pathways of the ear canal. For instance, a user may have several angles, bends, or curves in the ear canal. Furthermore still, dexterity or mobility limitations of older hearing aid users make the ability to manipulate and position the ear canal component even more difficult and frustrating.
- The ear canal component also lacks adequate surface area for a fingertip to manipulate the movement of the ear canal component. For instance, fingertip may slide past and alongside the ear canal component making manipulation of the ear canal component nearly impossible.
- Further, it should be noted that many components of the hearing aid, such as the ear canal components, the connector wire, and acoustical mini sound tube, are often very delicate. Substantial force on any component may cause damage, malfunction, and/or destruction of the hearing aid. Often times, a twisting motion is used by a user to attempt to achieve proper positioning, but this twisting motion can cause substantial damage to the hearing aid component.
- The resulting consequences of the problems described above for hearing aid users include loosely fitting hearing aids which may fall out and become lost, inadequate amplification which does not meet the prescribed needs of the hearing aid user, unwanted acoustical feedback, user frustration, damage to the hearing aid, diminished reputation for the hearing aid manufacturer, and/or reduced perception of the viability of hearing aids by users.
- Example prior attempts at solving the problems discussed above have been disclosed in
U.S. Patent Publication Nos. 2009/0285428 ,2009/0082801 and2006/0215862 . However, all disclosures have their own problems. It is also conceivable that these handheld tools may cause injury to the user if improperly inserted into the ear canal. For instance, inserting a tool too deeply into the ear canal may rupture to the tympanic membrane (ear drum) and/or injure the surface of the ear canal. Also, the user may lose the handheld tool. - This Summary is provided to introduce a selection of concepts that are further described herein below in the Detailed Description. This Summary is not intended to identify key or central features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
- In certain examples, an apparatus for controlling and positioning a device in a body cavity includes a cap configured to couple to the device such that the cap increases maneuverability of the device in the body cavity as the device is positioned in the ear canal.
- In certain examples, an apparatus for controlling and positioning of ear canal components in an ear canal. The apparatus comprising a cap with a first end portion configured to couple with the ear canal component such that the cap increases maneuverability of the ear canal component in the ear canal as the ear canal component is positioned in the ear canal. The cap including a gripping structure at a second end portion of the cap located opposite to said first end portion, wherein gripping structure projects in a direction away from the first end portion of the cap; and a projection at the second end portion of the cap, wherein the projection projects in a direction away from the first end portion of the cap. The gripping structures and the projection define a groove with a contact surface between them, wherein the groove is adapted to receive a fingernail.
- In certain examples, an assembly comprising an ear canal component of a hearing aid that is positionable in an ear canal and an apparatus for controlling and positioning the ear canal component in the ear canal. The apparatus comprising a cap for increasing maneuverability of the ear canal component in an ear canal. The cap including a gripping structure at a second end portion of the cap located opposite to said first end portion, wherein gripping structure projects in a direction away from the first end portion of the cap; and a projection at the second end portion of the cap, wherein the projection projects in a direction away from the first end portion of the cap. The gripping structures and the projection define a groove with a contact surface between them, wherein the groove is adapted to receive a fingernail. The cap is configured to increase maneuverability and control of the ear canal component as the ear canal component is positioned in the ear canal.

- The inventor has discovered through research and experimentation that it is advantageous for a hearing aid to include an apparatus that allows a user to control and position an ear canal component of the hearing aid into an ear canal. More specifically, the apparatus is an ergonomically designed fingertip fitting guide that couples to the ear canal component to increase the control of the ear canal component while the user positions the ear canal component into the ear canal. The apparatus can prevent damage to the hearing aid (such as the ear canal component) and/or sensitive ear structures.

- Referring to
FIGURE 1 , a device or hearingaid 20 with a fingertip or fingernail guide or apparatus 26 (described herein) is depicted inserted into thehuman ear 10. Thehearing aid 20 includes amain body 21, anear canal component 23, and a connector 22 (e.g. wire, acoustical mini sound tube) which couples theear canal component 23 to themain body 21. Themain body 21 of thehearing aid 20 includes other components of thehearing aid 20 including a power source, electronic processing equipment, and/or the like. Theear canal component 23 can include a receiver, a tip, portions of theconnector 22, and/or other hearing aid components that are positioned in an ear canal 15 (seeFIGURE 3 ). Certain examples of hearingaids 20 orear canal components 23 include a retention tail 24 (seeFIGURE 13 ) that maintains theear canal component 23 in position in theear canal 15 and/or increases the stability of theear canal component 23. - Referring to
FIGURE 2 , an exampleear canal component 23 is depicted, specifically a receiver and a portion of theconnector 22 of thehearing aid 20. - Referring to
FIGURE 3 , a typical cross sectional view of ahuman ear 10 is depicted. Theear 10 includescartilage 11,bones 12, atragus 13, bends 16, anear canal 15, and anear drum 17. For proper sound amplification, the ear canal component 23 (seeFIGURE 1 ) must be inserted into theear canal 15 and manually controlled, manipulated, and positioned sufficiently deep in theear canal 15. Theapparatus 26 assists in manipulating and positioning theear canal component 23 into theear canal 15. In one example, the user uses a fingernail 8 (seeFIGURE 1 ) to engage theapparatus 26. In other examples, the user can use other body parts and objects such as a tool, a tweezer, and/or the like to engage and/or contact theapparatus 26. - Referring to
FIGURES 4 ,5 ,6A-6H ,7A-7C ,8A-8C , and9A-9C ,example apparatuses 26 are shown in greater detail. Theapparatus 26 is coupled to theear canal component 23 and is utilized when positioning theear canal component 23 of thehearing aid 20 into theear canal 15. Theapparatus 26 includes a guide member orcap 28 configured to couple to theear canal component 23 such that thecap 28 supports thefingernail 8 and increases maneuverability of theear canal component 23 in theear canal 15 as theear canal component 23 is positioned in theear canal 15. Thecap 28 includes acontact surface 29 that is contacted by thefingernail 8 such that thefingernail 8 does not slip as the user positions theear canal component 23 in theear canal 15. Thecontact surface 29 can be a smooth surface or a textured surface such as etching, crosshatching, roughen surfaces, bumps, undulations, depressions, and/or the like. Thecap 28 includes a concave endwall 30 (described further herein) opposite thecontact surface 29. Thecap 28 can be any size and/or shape (e.g. circular, disc, spherical, triangular, rectangular). Theapparatus 26 can be coupled to theear canal component 23 by adhesive, friction, compression (i.e. theapparatus 26 elastically deforms when placed on theear canal component 23 such that thatapparatus 26 tightly grips theear canal component 23 such that theapparatus 26 is not easily removed), mechanical connection devices (e.g. screws), and/or the like. In other examples, theapparatus 26 may be integral with the ear canal component 23 (e.g. theapparatus 26 can be integral with a molded plastic cover of the receiver; theapparatus 26 can be integral with the dome of the hearing aid; theapparatus 26 can be integral with the ear canal component 32). Theapparatus 26 can be made of any suitable material such as elastic materials, rubber, silicon, flexible plastic, rigid plastic, ceramic, metal, and/or the like. - The
cap 28 includes a grippingstructure 33 that projects outwardly from thecontact surface 29 of thecap 28. Any number ofgripping structures 33 can be included with thecap 28. The grippingstructures 33 can be any suitable size and/or shape (e.g. rectangular, circular, triangular, concave). In certain examples, the grippingstructures 33 are truncated (seeFIGURE 4 ). The grippingstructure 33 includes a first end that is adjacent to thecontact surface 29 and a second end opposite the first end. The second end of the grippingstructure 33 includes a sloped surface that slopes toward the first end from an outer edge 80 (seeFIGURES 4-5 ) of thecap 28 towards the center of thecap 28. Thecap 28 includes a step orprojection 34 that projects outwardly from thecap 28 and defines agroove 35 between theprojection 34 and the grippingstructure 33. Thefingernail 8 can be received in thegroove 35 between theprojection 34 and the grippingstructure 33. The illustrated number ofgripping structures 33 and/orprojections 34 included with thecap 28 is merely exemplary and can vary from that which is shown. For example,FIGURE 4 depicts three gripping structures 33 (one grippingstructure 33 is hidden by the depicted fingernail 8) andFIGURE 5 depicts fourgripping structures 33. In certain examples, thecap 28 may be devoid of grippingstructures 33. In certain examples, theprojection 34 and a plurality ofgripping structures 33 define a plurality ofgrooves 35 between theprojection 34 and the plurality ofgripping structures 33. In certain examples, thegrooves 35 are shaped to receive a curved fingernail 8 (e.g. thegroove 35 is arc shaped having curvature similar to the curvature of a typical fingernail). The grippingstructures 33 and/or theprojection 34 can comprise the same material as the rest of theapparatus 26 or different materials. - The
cap 28 defines a connector hole 40 (seeFIGURE 7A ) and includes a cap slit 41 that intersects theconnector hole 40. Theconnector hole 40 receives theconnector 22 of the hearing aid 20 (seeFIGURE 2 ). The size and/or shape of theconnector hole 40 can vary based on the dimensions of the ear canal component 23 (e.g. theconnector hole 40 is circular or oval in shape). In certain examples, the diameter of theconnector hole 40 is equal to the diameter of theconnector 22. Theconnector hole 40 can be located in the center of thecap 28 on a center axis (not shown). In other examples, theconnector hole 40 is radially offset from the center of thecap 28. - The cap slit 41 intersects the
connector hole 40 and theouter edge 80 of thecap 28. Thecap 28 is configured to elastically deform as thecap 28 couples to theear canal component 23 such that the cap slit 41 opens whereby the user can position theconnector 22 into theconnector hole 40. When theconnector 22 has been properly received in theconnector hole 40, the cap slit 41 returns to a closed position such that theconnector 22 is not easily moved from theconnector hole 40 without an appropriate force and/or theapparatus 26 is not easily removed from theconnector 22 and/or theear canal component 23. In a closed position, two surfaces of the cap slit 41 can contact each other. In certain examples, the cap slit 41 is a cut in thecap 28 between theconnector hole 40 and theouter edge 80 that defines two surfaces that abut each other in the closed position and separate from each other in an open position. In other examples, a space or gap may separate the two surfaces of the cap slit 41. - The
apparatus 26 includes asidewall 48 coupled to thecap 28. Thesidewall 48 engages and/or couples to theear canal component 23, and thesidewall 48 defines acavity 49 that is configured to receive theear canal component 23. In certain examples, thecap 28 includes theconcave endwall 30 that defines aclosed end 50 of the cavity 49 (seeFIGURE 6E ). Thesidewall 48 is configured to couple with theear canal component 23 by surrounding or encircling theear canal component 23. Thesidewall 48 couples to theear canal component 23 by adhesive, friction, compression (i.e. thesidewall 48 elastically deforms when coupled to theear canal component 23 such that thesidewall 48 tightly grips theear canal component 23 and theapparatus 26 is not easily removed), mechanical connection devices (e.g. screws), and/or the like. In one example, thesidewall 48 elastically deforms as the user stretches thesidewall 48 around theear canal component 23. Thesidewall 48 can be any size and/or shape. In certain examples, thesidewall 48 is annular. Thesidewall 48 can be made of any suitable material such as elastic materials, rubber, silicon, flexible plastic, rigid plastic, ceramic, metal, and/or the like. Thesidewall 48 can be made from the same material of thecap 28 or made from a different material. - Referring to
FIGURES 6E ,10A ,10B ,11A, and 11B , thesidewall 48 can include a plurality of fins orribs 55 that project into thecavity 49 and are configured to deform as thecavity 49 receives theear canal component 23 such that theribs 55 couple to and/or engage with theear canal component 23. Theribs 55 are integrally coupled to thesidewall 48 and are made of any suitable material. The structure (e.g. projections, detents, suction cups, textured pads), size, and/or the shape of theribs 55 can vary. For example, theribs 55 depicted inFIGURES 10A and 10B are smaller and have a different shape when compared to theribs 55 depicted inFIGURES 11A and 11B . In certain examples, theribs 55 can be stepped in height and/or width such that the rib height and/or width increases from anopen end 51 of thecavity 49 to theclosed end 50 of thecavity 49 such that engagement or coupling between theribs 55 and theear canal component 23 increases as theear canal component 23 is inserted further into thecavity 49. - Referring to
FIGURES 10A and11A , theribs 55 are depicted in an erect or undeformed position. Referring toFIGURES 10B and11B , theribs 55 are depicted in a collapsed or deformed position such as when theear canal component 23 is received by thecavity 49. Theribs 55 deform, collapse, are received in pockets (not shown), and/or move relative each other while moving from the undeformed position to the deformed position. In certain examples, theribs 55 fold onto or overlapadjacent ribs 55. In certain examples, theribs 55 fold or collapse into pockets (not shown). Theribs 55 are configured to accommodateear canal components 23 having different shapes and sizes (i.e. asingle apparatus 26 having thesidewall 48 with theribs 55 accommodates several differentear canal components 23 manufactured by different hearing aid manufacturers). Often, hearing aid manufacturers manufacturevarious hearing aids 20 with different attributes (e.g. size, dimensions, shapes). - Referring to
FIGURES 15-16 , thesidewall 48 includes anouter surface 57 that defines sidewall channels orslots 58. Thesidewall channels 58 are opposite theribs 55 relative to thesidewall 48. Thesidewall channels 58 receive and/or mate withfingers 74 of a retention tail 70 (to be described below). - In
certain example apparatuses 26 thesidewall 48 is flush withcap 28 such that there is no edge or surface between thesidewall 48 and the cap 28 (seeFIGURES 6A-6H ). In other examples, thecap 28 includes alower surface 38 positioned between thecap 28 and thesidewall 48 such that thesidewall 48 is inset from theouter edge 80 of the cap 28 (seeFIGURES 7A-7C ,8A-8C , and9A-9C ). Referring toFIGURES 9A-9C , thesidewall 48 includes atop surface 60 adjacent to thecap 28. - The
sidewall 48 includes a sidewall slit 56 that aligns with the cap slit 41 (seeFIGURES 6C ,7C , and9C ). The sidewall slit 56 opens as the user elastically deforms thesidewall 48 to position theear canal component 23 in thecavity 49. When theear canal component 23 has been properly received in thecavity 49, the sidewall slit 56 returns to a closed position such that theear canal component 23 is not easily moved from theapparatus 26 without an appropriate force. In a closed position, two opposite surfaces of the sidewall slit 56 can contact each other. In other examples, a space or gap may separate the two edges of the sidewall slit 56. - The present inventor has also recognized that
ear canals 15 that are longer and require deeper insertion of thehearing aid 20 orear canal component 23 can cause the retention tail 24 (seeFIGURE 13 ) to not lie properly in the concha bowl 18 of the pinna (outer ear) and stick straight-out of the pinna because theear canal component 23 is situated deep into theear canal 15 such that theretention tail 24 is out of alignment with (e.g. not perpendicular to) the concha bowl 18. Accordingly, theapparatus 26 can be configured to increase the length of theear canal component 23 to maintain proper alignment of theretention tail 24. Referring toFIGURES 12 and13 , theapparatus 26 defines aretention tail opening 59 that is configured to receive aretention tail 24 of thehearing aid 20. Theretention tail opening 59 can be defined in thecap 28 and/or thesidewall 48. In certain examples, theretention tail opening 59 extends transverse to theconnector hole 40. - Referring to
FIGURES 14A-14G ,15 , and16 , the apparatus includes aretention tail 70 that is removably coupled to thesidewall 48. Theretention tail 70 is configured to retain theear canal component 23 in theear canal 15. Theretention tail 70 includes acollar 72 that defines abore 73 that receives thesidewall 48. Thecollar 72 comprises a plurality offingers 74 that project into thebore 73 of thecollar 72.

Any number offingers 74 can be included, and thefingers 74 can be any suitable size and/or shape (e.g. rectangular, circular, triangular, concave). In certain examples, thefingers 74 include afirst end 75, asecond end 76, and asloped surface 77 that slopes inwardly from thesecond end 76 to thefirst end 75. The shape of the concha bowl 18 can vary, and some concha bowls 18 include deep valleys in which theretention tail 24 lays. In certain examples, the concha bowl 18 does not include a deep valley below theear canal 15 and theretention tail 24 must lie in the upper portion of the concha bowl 18. The plurality offingers 74 andsidewall channels 58 allows the user to position of theretention tail 70 in different positions relative to the sidewall 48 (i.e. theretention tail 70 can extend upwardly; theretention tail 70 can be positioned downwardly). Theretention tail 70 can be indexed relative to thesidewall 48 such that theretention tail 70 can extend in a plurality of positions (i.e. theretention tail 70 can be indexed relative to thesidewall 48 such that thefingers 74 engage thesidewall channels 58 and theretention tail 70 extends in a selected position). - In certain examples, the
retention tail 70 in permanently coupled and integral to theapparatus 26.
