ABSTRACT:
A ductal access device is provided for accessing a breast duct and collecting biological material from within the duct. The access device may include an elongated member having an outer diameter sized for positioning within the breast duct and an internal lumen for infusing a fluid into the breast duct and collecting fluid from the breast duct. The elongated member may include a central axis extending through the internal lumen and a different axis being parallel to the central axis defining an off-axis configuration. An elongated distal tip extends beyond the distal end of the internal lumen and along the different axis. The elongated distal tip has a closed distal end for navigating within the breast duct. The elongated distal tip may include an internal passageway that is sized to slidiably or removably receive an elongated introducer.
