Abstract
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.
