Abstract
A device, including an electrode array carrier, that carries one or more electrode arrays, and a therapeutic substance such as for example an anti-inflammatory, wherein the therapeutic substance is located in at least one cavity of the carrier, the cavity having at least one of a non-uniform depth or a non-uniform width with respect to location in a direction of the depth that has an effective impact on a delivery of the therapeutic substance to a human.
Claims20
A method, comprising:
- obtaining an electrode array carrier having therein at least one void, the electrode array carrier being a stock electrode carrier and the voids being common to other electrode array carriers of the stock;
- and
- providing a therapeutic substance into the at least one void, wherein the action of providing the therapeutic substance into the at least one void results in a specific therapeutic substance delivery profile when the electrode array carrier is implanted in a human.
A device, comprising:
- a plurality of electrodes;
- an electrode array carrier;
- and
- a therapeutic substance, wherein the therapeutic substance is located in at least one recess of the carrier, the recess extending along the electrode array a distance that passes a plurality of electrodes.
1 more element
A method, comprising:
- delivering a therapeutic substance to a cochlea of a recipient from a cochlear implant electrode array carrier, wherein a delivery rate by weight over a period of time is variable owing to a geometry of the carrier containing the therapeutic substance.
