摘要：
A system is provided that includes an elongated introducer navigable through body vessels of a human subject and a pusher component for incorporation within the introducer. The pusher component includes a tubular portion with a spiral ribbon. A radiopaque marker is secured to at least a portion of the spiral ribbon such that an outer surface of the radiopaque marker is substantially flush with an outer surface of the tubular portion immediately proximal and/or immediately distal the radiopaque marker. According to a method of manufacturing such a component, the spiral ribbon is formed by a spiral cutting operation and a pre-assembly radiopaque marker member is crimped onto the spiral ribbon. According to another method of manufacturing such a component, the spiral ribbon is formed by winding a filament and a pre-assembly radiopaque marker member is crimped onto the spiral ribbon.
