摘要:
A method (10) of forming an electrically conducting feedthrough. The method (10) comprises a first step (11) of forming an electrically conductive structure (21) comprising a sacrificial component and a non-sacrificial component. At least a portion of the non-sacrificial component can then be coated with a relatively electrically insulating material (35) prior to removal of at least a portion of the sacrificial component from the electrically conductive structure. The structure of the feedthrough provides electrical connection through the wall of a housing of an implantable component while preventing unwanted transfer of materials between the interior of the component and the surrounding environment.

An active implantable medical device (AIMD). The AIMD comprises: a knitted electrode assembly comprising: at least one biocompatible, electrically non-conductive filament arranged in substantially parallel rows each stitched to an adjacent row, and at least one biocompatible, electrically conductive filament having a first end intertwined with a first row of the at least one non-conductive filament, and a second end intertwined with a second row of the at least one non-conductive filament, wherein the first and second rows are spaced from one another.

Methods of forming a feedthrough using a mold that defines a cavity when closed and includes one or more cores configured to move in and out of the mold cavity. The methods include injecting non-electrically conductive powder injection molding (PIM) feedstock into the mold cavity to form an insulative body around a portion of each of the cores disposed in the mold cavity, removing each of the cores from the insulative body to form one or more core cavities in the insulative body, injecting electrically conductive PIM feedstock into the core cavities to form one or more conductors in the core cavities, respectively, and sintering the insulative body and the conductors to form the feedthrough.

摘要:
An embodiment of the present invention takes masking effects into consideration when determining stimulation signals for neural stimulation. These masking effects may be modeled using user-specific models determined by taking measurements for an implant system of an implant recipient. Or, the model may correspond to a group of individuals sharing a common characteristic or the population as a whole. These models may be, for example, psycho-physical models.
