A method for using 3D printing technology produces personalized biomimetic drug-eluting coronary stent and the product thereof. The process of manufacturing stent, based on coronary angiography imaging data, measures the diameter of diseased coronary and conducts 3D reconstruction. A personalized stent for each patient according to diameter, length, and morphological characteristics of target vessel that suited to the lesion is produced. The coronary stent is formed from biodegradable poly-L-lactic acid (PLLA) or other materials. The stent is modeled by 3D printing and then coated with polymers carrying antiproliferative drug to reduce restenosis (the polymers is a mixture of antiproliferative drug and PDLLA at a ratio of 1:1). The biomimetic drug-eluting coronary stent produced by 3D printing technology is personalized stent for each patient according to different characteristics of diseased coronary, reduces the incidence of vascular injury, thrombosis, dissection and other complications caused by stent and vessel diameter mismatch.

An artificial tissue including an internal mass transport network having a plurality of channels, wherein the channels are designed to substantially mimic naturally occurring vascular network and a method for creating an internal transport system within a tissue scaffold to improve circulation, diffusion, and mass transport properties by utilizing computer-aided tissue engineering (CATE). The artificial tissue has the internal mass transport network of channels embedded, deposited, or molded within a scaffold, wherein the channels are made from a biodegradable transporting material and the scaffold is made from a scaffold material. The artificial tissue of the invention includes a basic circulatory system embedded within the tissue scaffold. This system provides mass transport throughout the entire scaffold and degrades after the new circulatory system develops.

A planetary scale object rendering system may provide a plurality of spherical mesh topologies of different levels of detail made up of abutting faces. Tessellation of the faces may be provided at continuous levels of detail. The geometry data at different locations and levels of detail in the mesh topology may be randomly accessible. The geometric data may be organized in quadtrees in some embodiments. A layered quadtree data structure may be formed from the bottom layer up with successively higher parent layers formed from the root nodes of previous child layers. The quadtree structure may be randomly accessed from the top down.
