At least one strut is composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The delivery system includes a catheter and a stent disposed on a portion of the catheter. The stent includes a framework composed of a biodegradable material. The stent further includes at least one strut composed of a non-biodegradable material. The framework is operably attached to the at least one strut. The method includes positioning an intraluminal stent via a catheter within a vessel.
