Biodegradable stents can support vessels for an extended period, maintain vascular
patency, and progressively degrade once vascular remodeling is completed, thereby …

In this study, four novel three-dimensional (3D) warp and woof structures with negative
Poisson's ratio (NPR) were designed and assembled using the interlocking assembly …

This paper presents a conceptual design and finite element (FE) simulation of a novel class
of negative Poisson's ratio (NPR) stents with hybrid auxetic structures fabricated by FDM 3D …

The re-entrant auxetic topology was one of the first unit-cells proposed to build cellular
auxetic structures. This unit cell (UC) is still widely used in energy-absorbing systems, but …

Anti-tetra chiral honeycomb is a typical auxetic metamaterial that exhibits excellent auxetic
behavior. Based on anti-tetra chiral honeycomb, previous studies proposed a 3D tubular …

With the rising popularity of endovascular aortic repair (EVAR) for aortic aneurysms and
dissections, there is a crucial need for investigating the delayed appearance of post-EVAR …

In this paper, a novel 3D composite auxetic tubular structure (3D CATS) connected by a thin-
walled (TW) circular tube was proposed, and two sets of parameters h 1, h 2, and β, n were …

Additive manufacturing has enabled the fabrication of lightweight complex metamaterials
that possess high energy absorption and impact resistance properties. Stents, a typical 3D …

Introduction Numerical simulations have demonstrated the superior bending flexibility of
auxetic stents compared to conventional stent designs for endovascular procedures …

Conventional stents have some limitations, such as dogboning and foreshortening, that can
lead to issues like in-stent restenosis and thrombosis. Negative Poisson's ratio stents, called …
