An apparatus for securing a marker wire relative to a lumen includes a hub to which the marker wire is secured. The hub includes a feature that secures the hub to an outer surface of the lumen. For example, the hub may include a base member secured to the marker wire and a separate fastener member which secures the hub to an outer surface of a lumen, where the base member includes a split tube segment that receives the lumen within an inner cylindrical opening. Alternatively, the hub may include a cylindrical slide lock collar member with a split tubular extension that receives the lumen within an inner cylindrical opening. Locking features may be included to help fix the two pieces of the hub in position relative to each other.
