Scaffold comprising surface hyperboloid structure, methods for fabrication and use thereof

Abstract

Provided herein are a scaffold having a surface hyperboloid structure and its fabrication method and application. The scaffold has internally disposed with pores where each of the pores connects with each other and any point on a surface of each of the pores has the hyperboloid structure. Since the surface of the scaffold is smooth and stress concentration is thereby avoided, the scaffold can withstand a greater external force in the case of the same porosity. Moreover, since the pores inside the scaffold connect with each other, the scaffold has a better permeability to fluid and is more conducive to tissue ingrowth. In addition, the scaffold has a large internal surface area, rendering it feasible to subsequent surface treatment, such as film coating, to be carried out on the internal surface of the scaffold.
