Abstract
At least some embodiments of the present disclosure are directed to systems and methods for sleep disordered breathing (e.g., obstructive sleep apnea) therapy. An electrode assembly includes a cuff body to wrap around a nerve. The cuff body includes an inner layer to form a hollowed cylinder shape, and an outer layer to overlap at least a part of the inner layer and cover a closeable opening of the inner layer. Electrode elements are at least partially embedded within the inner layer and spaced apart from each other along a longitudinal direction. The electrode elements each include an arcuate portion facing a lumen of the inner layer. The electrode assembly has a cross-sectional shape that is substantially circular.

-30. (canceled)
An apparatus, comprising:
- a cuff body configured to be disposed around a nerve, the cuff body including:
- an inner layer defining a lumen configured to receive a portion of the nerve, the inner layer having an outer surface and an inner surface, the outer surface of the inner layer defining a cylindrical profile with a first cross-section having a first center, the inner surface of the inner layer forming a second cylindrical profile with a second cross-section having a second center, the first center and the second center being offset with respect to each other;
- a closeable opening defined in the inner layer;
- and
- an outer layer configured to overlap at least a portion of the inner layer to cover the closeable opening;
- and
- one or more electrode elements coupled to the inner layer and configured to stimulate the nerve when the cuff body is disposed around the nerve.
An apparatus, comprising:
- a cuff body configured to be disposed around a nerve, the cuff body including:
- a wall defining a lumen configured to receive a portion of the nerve therethrough, the wall including an outer surface and an inner surface, the outer surface defining a first shape with a first cross-section having a first center, the inner surface defining a second shape with a second cross-section having a second center, the first center and the second center being offset with respect to each other;
- a closeable opening defined in the wall and extending longitudinally along the wall, the closeable opening configured to allow the nerve to be received within the lumen;
- and
- one or more electrode elements coupled to the wall and configured to stimulate the nerve when the cuff body is disposed around the nerve.
An apparatus, comprising:
- a cuff body configured to be disposed around a nerve, the cuff body including:
- an inner layer defining a lumen configured to receive a portion of the nerve, the inner layer defining a closeable opening therein extending longitudinally along the inner layer and configured to allow the nerve to be received in the lumen, and
- an outer layer configured to overlap at least part of the inner layer and cover the closeable opening,
- the inner layer having a first thickness at a first portion of the inner layer proximate to the closeable opening and a second thickness at a second portion of the inner layer, the first thickness being smaller than the second thickness;
- and
- one or more electrode elements coupled to the inner layer and configured to stimulate the nerve when the cuff body is disposed around the nerve.
