Abstract
A medical device, such as a prosthesis, and method of forming the same are disclosed. The medical device includes a cover material and a reinforcement element, and may include a stent frame structure. The reinforcement element includes a plurality of bends disposed about a pattern axis. The pattern axis is arranged helically along the cover material.
Claims20
A prosthesis comprising:
- a radially expandable stent frame structure;
- a cover material disposed along the stent frame structure;
- and
- a reinforcement element coupled to the cover material, the reinforcement element having a plurality of bends disposed about a pattern axis, the pattern axis arranged helically along the cover material,
- wherein the cover material includes an outer layer disposed along an outer surface of the frame structure, and an inner layer disposed along an inner surface of the frame structure,
- where the radially expandable stent frame structure comprises a plurality of stents that are axially disposed away from one another about a longitudinal axis of the cover material, such that the plurality of stents each form a closed shape when viewed in a direction substantially orthogonal relative to the main longitudinal axis of the cover material.
