3. The apparatus of claim 1 , wherein each of the attachment structures include a bendable T-shaped tab that is integrally connected with the thin film body.

4. The apparatus of claim 1 , wherein at least a first subset of the attachment structures is located on an edge of the thin film body.

5. The apparatus of claim 4 , wherein at least a second subset of the attachment structures are cutout tabs located in an internal area of the thin film body away from the edge of the thin film body.

6. The apparatus of claim 1 , wherein the attachment structures each protrude at an angle with respect to a planar surface of the thin film body.

7. The apparatus of claim 1 , wherein each of the attachment structures is bendable about an axis prior to being surrounded by the outer molding.

8. The apparatus of claim 1 , wherein:

the thin film body includes a polyimide substrate; and

the outer molding includes silicone.

9. The apparatus of claim 1 , wherein:

the electrodes are configured to deliver an electrical stimulation therapy from a first side of the thin film body; and

the outer molding is disposed on a second side of the thin film body opposite the first side.

10. The apparatus of claim 9 , wherein none of the outer molding is disposed directly on the first side of the thin film body.

11. The apparatus of claim 9 , wherein a surface of each of the electrodes is flush with a surface of the thin film body at the first side.

12. The apparatus of claim 1 , wherein the thin film body is curved.

13. An apparatus, comprising:

a thin film body extending from a first end to a second end;

a plurality of electrodes disposed on the thin film body, wherein the electrodes are configured to deliver electrical stimulation to a nerve issue located adjacent to a first side of the thin film body;

a plurality of electrode connection traces that are each coupled to a respective one of the electrodes, wherein the electrode connection traces are connectable with a multi-lumen lead;

a plurality of attachment structures disposed at different locations of the thin film body; and

an outer molding surrounding the thin film body and the electrode connection traces, wherein the attachment structures each protrude into the outer molding from a second side of the thin film body.

14. The apparatus of claim 13 , wherein each of the attachment structures include a bendable tab that is integrally connected with the thin film body, wherein the bendable tab has a T-shaped profile.

15. The apparatus of claim 13 , wherein:

at least a first subset of the attachment structures is located on an edge of the thin film body; and

at least a second subset of the attachment structures are cutout tabs located in an internal area of the thin film body away from the edge of the thin film body.

16. The apparatus of claim 13 , wherein the attachment structures each protrude at an angle with respect to a planar surface of the thin film body.

17. The apparatus of claim 13 , wherein:

each of the attachment structures is bendable about an axis before the attachment structures are protruded into the outer molding;

the thin film body is curved and includes a polyimide material; and

the outer molding includes a silicone material.

18. The apparatus of claim 13 , wherein:

no portion of the outer molding is disposed directly on the first side of the thin film body; and

a surface of each of the electrodes is coplanar with a surface of the thin film body at the first side.

19. An apparatus, comprising:

a thin film body extending from a first end to a second end, wherein the thin film body includes a polyimide material;

a plurality of electrodes disposed on the thin film body, wherein the electrodes are configured to deliver an electrical stimulation therapy from a first side of the thin film body;

a plurality of electrode connection traces that are each coupled to a respective one of the electrodes;

a plurality of attachment structures placed at predetermined locations about the thin film body; and

an outer molding disposed on a second side of the thin film body opposite the first side, wherein each of the attachment structures protrude toward and terminate into the outer molding, wherein the outer molding includes a silicone material, and wherein each of the attachment structures is bendable about an axis prior to being surrounded by the outer molding.

20. The apparatus of claim 19 , wherein:

each of the attachment structures include a bendable tab that is integrally connected with the thin film body, wherein the bendable tab has a T-shaped profile;

at least a first subset of the attachment structures is located on an edge of the thin film body; and

at least a second subset of the attachment structures are cutout tabs located in an internal area of the thin film body away from the edge of the thin film body.
