Abstract:
1. A method for fabricating a stent comprising: forming a suspension solution including a fluid, a biodegradable polymer and bioceramic particles, wherein the polymer is dissolved in the fluid, and wherein the bioceramic particles are dispersed in the solution; combining the suspension solution with a second fluid, wherein the second fluid is a poor solvent for the polymer; allowing at least some of the polymer to precipitate upon combining the suspension solution with the second fluid, wherein at least some of the bioceramic particles precipitate with the precipitated polymer to form a composite mixture; and fabricating a scaffolding including a pattern of interconnecting struts from the composite mixture, wherein the composite mixture is between 0.01% and 10% bioceramic particles by weight as compared to the polymer of the composite.
