NEW ROCHELLE, N.Y. – Might 18, 2017 – PRLog — A new examine demonstrates evidence-of-idea for combining computational layout and simulation tools with 3D printing technology to create self-expandable polymer stents that can grow with pediatric patients, are biodegradable, and call for only a minimally-invasive process for implantation. This progressive approach is described in an report in 3D Printing and Additive Manufacturing, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers (http://www.liebertpub.com/)
M.S. Cabrera, B. Sanders, O.J.G.M. Goor, A. Driessen-Mol, C.W.J. Oomens, and F.P.T. Baaijens, Eindhoven University of Technologies, the Netherlands, coauthored the review entitled “Computationally Made 3D Printed Self-Expandable Polymer Stents with Biodegradation Capacity for Minimally-Invasive Heart Valve Implantation:
To conquer the recent difficulties in creating bioabsorbable polymer stents with the necessary mechanical properties for use in minimally invasive procedures to implant tissue-engineered heart valves in youthful sufferers, researchers have developed a novel strategy to generate stents with development potential and a sufficient degree of plastic deformation. The speedy prototyping method they describe entails generating an in silico model of a traditional nitinol stent and then translating the computational simulation into prototype stents using 3D printing and a versatile copolyester elastomer. The authors evaluated the mechanical properties of the stents by subjecting them to crush and crimping tests, and performed accelerated degradation exams to assess their biodegradability.
