Combining 3D Printing and Electrospinning for the Fabrication of a Bioabsorbable Poly-p-dioxanone Stent
For a good radial strength and small volume,the metal stent is widely applied in treating vascular disease.However,because metal stents can form a fixed stenosis in the treated area of vascular disease,it is not appropriate for treating children who are growing up.Bioabsorbable vascular stent (BVS) is the ideal choice for children.Aiming at overcoming the defects in mechanical properties of existing vascular stents,a sliding-lock bioabsorbable poly-p-dioxanone (PPDO) vascular stent,which is fabricated through combining 3D printing and electrospinning technology,is proposed herein.The results of experiments show that when the thickness of a stent is constant,the stent combined with electrospinning is obviously better than one fabricated through 3D printing.In addition,it is very favorable for the growth and proliferation of cells.This fabrication process lays the foundation for further applying the stent in treating vascular disease in children.
