Abstract
A implantable neural electrode assembly is described. The implantable neural electrode assembly includes a plurality of open-ended rings alternatingly connected to a spine. An inner layer of the open-ended rings is formed from a drug-loaded material (e.g., silicone that has been loaded with a steroid) and an outer layer is formed from a drug-free material. One or more electrode assemblies are connected to the inner layer and oriented towards a center of a cylinder defined by the plurality of open-ended rings.
Claims17
An electrode assembly, comprising:
- a spine to support a lead conductor;
- and
- a first open-ended ring comprising a first connected end connected to the spine and a first open end, the first open-ended ring comprising:
- a first layer defining an interior surface of the first open-ended ring, the first layer formed from a drug-loaded silicone, the interior surface oriented toward a center of the first open-ended ring;
- a first electrode fixedly supported by the first layer and disposed at the interior surface, the first electrode configured to electrically connect to the lead conductor;
- and
- a second layer defining an exterior surface of the first open-ended ring, the second layer formed from a drug-free silicone, the exterior surface oriented away from the center of the first open-ended ring.
