Implantable receptacle for a hearing aid component
An implantable receptacle for receiving a hearing aid component includes a body having a proximal portion, a distal cylindrical portion and a joining portion joining the proximal portion to the distal cylindrical portion. First flexible tines extending from an outer wall of the distal cylindrical portion in the general direction of the proximal portion are configured to engage with and lock the distal cylindrical portion to a wall of a fenestration in a bone of the patient in a permanent fashion in response to pressing the sleeve into the fenestration. Second flexible tines extending from an outer wall of the distal cylindrical portion in a direction generally tangential to the circumference of the distal cylindrical portion are configured to engage with and prevent rotation of the distal cylindrical portion within the wall of the fenestration.
1. An implantable receptacle for receiving a hearing aid component, the receptacle comprising:
a body having a proximal portion, a distal cylindrical portion and a joining portion joining the proximal portion to the distal cylindrical portion;
the proximal portion having a first cross-sectional maximum axial diameter and the distal portion having a second, smaller, maximum cross-sectional axial diameter;
a first plurality of flexible first tines formed in the wall of the distal cylindrical portion, each of the first tines extending from an outer wall of the distal cylindrical portion in a direction of the proximal portion and configured to engage with and lock the distal cylindrical portion to a wall of a fenestration in a bone of the patient in response to pressing a sleeve into the fenestration; and
a second plurality of flexible second tines formed in the wall of the distal cylindrical portion, each of the second tines extending from the outer surface of the wall of the distal cylindrical portion in a direction tangential to the circumference of the distal cylindrical portion such that each of the second tines are perpendicular to the direction of the proximal portion and configured to engage with and prevent rotation of the distal cylindrical portion within the wall of the fenestration.
2. The receptacle of claim 1 , wherein the proximal portion is cylindrical and includes at least one bayonet-type locking sleeve configured to engage with at least one corresponding pin extending from the hearing aid component and removably lock the hearing aid component to the receptacle.
3. The receptacle of claim 2 , wherein the receptacle comprises titanium.
4. The receptacle of claim 2 , wherein the receptacle is formed entirely from titanium.
5. The receptacle of claim 1 , wherein the receptacle comprises titanium.
6. The receptacle of claim 1 , wherein the receptacle is formed entirely from titanium.
