Abstract

A composite wire product includes a biodegradable parent material which forms the bulk of the cross-sectional area of the wire, and a central fiber or filament of a slower-degrading or non-biodegradable material runs throughout the length of the wire. This central filament promotes the mechanical integrity of an intraluminal appliance or other medical device made from the wire product throughout the biodegradation process by preventing non-absorbed parent material from dislodging from the central filament. Thus, the present wire design enables the creation of medical devices that are designed to improve in flexibility toward a more natural state over the course of healing, while also controlling for the possibility of non-uniform in vivo erosion.
