摘要： Implantable medical devices have zones of high in vivo stability that are adjacent to zones of relatively low in vivo stability, so that when these medical devices are implanted into a host, the zones of low in vivo stability degrade first and allow the formation of independent segments of relatively intact high in vivo stability bands that are sufficiently small that they may pass from the host in a non-harmful manner.

摘要： Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.
