PLASMA ENHANCED POLYMER ULTRA-THIN MULTI-LAYER PACKAGING

摘要

Abstract An implantable medical device including a plurality of components on a substrate, and a biocompatible multi-layer polymeric coating applied by vapour deposition to conform to and sealingly cover at least a portion of the components and/or the substrate. The coating is applied in at least two pairs of layers, wherein each pair has one layer formed by dissociation of a precursor and then simple deposition of that precursor, and the other layer is formed by at least one of plasma dissociation and excitation of the precursor to form a plasma-enhanced precursor, and then deposition of the plasma-enhanced precursor.
