First Claim
Patent Images
1. A method for implanting a hearing aid transducer within a patient, the method comprising the steps of:
- mounting a transducer body subcutaneously within the patient;
aligning an aperture in a first side of the transducer body with a desired interface point on a middle ear component;
securing the transducer body in the aligned position relative to the desired interface point; and
advancing an actuator through the aperture toward the middle ear component.

Abstract
A hearing aid transducer that includes an actuator advanceable relative to the transducer to couple with a middle ear component. In one aspect of the invention, the actuator is a separate structure from the transducer that is insertable into an aperture defined between a first and second end of the transducer. This permits separate connection of the actuator to the middle ear component and the transducer to improve coupling of the transducer to the middle ear component, e.g., minimizing loads on the middle ear component.

19. A method for operating an implantable transducer, the method comprising the steps of:
-
receiving transducer drive signals in the transducer; processing the drive signals to axially vibrate a tube movably connected within an aperture defined in the transducer between first and second sides thereof; and axially vibrating, with the tube, an actuator connected to the tube to stimulate a middle ear component.
