Abstract
A grooved stent (100) is provided. Support units (33) are arranged on two sides of a mesh region (30), and the support units (33) can move relative to the mesh region (30) to achieve a certain force buffering effect under pressure. Meanwhile, a gap is reserved between each support unit (33) and the mesh region (30), which provides space for deformation under pressure, to achieve a better buffering effect and to better maintain an overall shape of a bottom support sheet (3). A grooved stent (100) is further provided. The radial size of an end close to an axial edge of a groove (5) of a bottom support sheet (3) is less than the maximum radial size of the bottom support sheet (3), which is conducive to formation of a structure for directing toward a branch port.
