Graphic Details
It's a magnificent convergence of 3D printing and medicine where a new generation of vascular bioresorbable stents (BRS) can be 3D printed directly from fully biodegradable polymeric raw material pellets. As an advanced form of additive manufacturing, not only does our proprietary Multi-Axial Scaffold Extrusion (MASE) technology save on the raw materials, reduce the production times and lower the manufacturing costs, but also can fabricate complex stent structures and dimesons that cannot be produced by the laser cutting method. The patented closed-cell strut structure with fused joints provides both excellent flexibility and structural stability for the stent. The thin and round struts are easier to embed into the blood vessel wall for good stent apposition to reduce the interference with the blood flow. In the clinical trial production, all AMSorb® and PeriSorb® BRS units were manufactured in a Class 10,000 clean room environment using the MASE equipment custom designed and made at AMET. The BRS production output can be readily scaled up by installing as many MASE equipment stations as needed (each output: ∼40 units/hr.), without such a high capital cost as the laser cutting equipment.
