AI Technical Summary
Existing medical stents and stent-grafts face challenges in efficiently expanding to maintain a desired diameter within the body lumen while minimizing delivery profile and reducing the risk of access site complications.
A self-expanding endoprosthesis with a stent element and graft component, where the stent element exerts a radially expansive force on the graft component, which has a higher yield strength to maintain the expanded diameter, and is configured to reduce to a delivery configuration for minimally invasive insertion, with the stent element undergoing plastic strain to facilitate deployment.
The solution allows for effective expansion and maintenance of the desired diameter within the body lumen, reducing the risk of complications and enabling minimally invasive delivery by minimizing the delivery profile.
