Abstract
Composite catheter braids can be formed from a plurality of filaments, some of which can include significant amounts of molybdenum. Filaments including stainless steel and other materials can be used in combination with filaments including molybdenum. Individual filaments can be composed of single metals, or can represent alloys. Composite catheter braids can be employed in intravascular catheters.
