Abstract
The present invention is directed to implantable hearing aid systems and provides for selective interconnection between two or more implantable components of a system. The inventive apparatus comprises a first connector interconnected to a first implantable component and a second connector interconnected to a second implantable component which is separate from the first implanted component. The first and second connectors may each comprise outer housings and internal conductors, wherein the outer housings are configured to define male and female connectors for mating interconnection therebetween. In one arrangement, a female connector is defined by a support structure that also supports an interconnected implantable component (e.g., a processor unit and/or induction coil), and wherein the male connector is interconnected to another, separate component (e.g., a middle ear actuator). The support structure may be integrally defined by a molded material (e.g., a silicon-based material). One or more locking member(s) may be provided for selective insertion into the outer housing of the female connector to securably engage the male connector (e.g., the central conductor thereof). The invention facilitates in situ interconnection of plural implantable components in an implantable hearing aid system, and further allows for selective removal/repositioning of one or more of the interconnected components.
