Devices, methods and systems for collecting material from a breast duct

A device for accessing a breast duct and performing ductal lavage, said device comprising:

• a fluid hub comprising a proximal end, a distal end and at least three openings;
• and
• an elongated member for positioning within the breast duct comprising an internal lumen for infusing fluid into the breast duct and retrieving fluid from within the duct, said lumen being in communication with said openings of said fluid hub, and a length sized such that a distal end of said elongated member is positioned distal a ductal sphincter and proximal a portion of the breast duct to be lavaged when said distal end of said hub is proximate a ductal opening on a nipple surface.

A device for accessing a breast duct having multiple branches and performing ductal lavage within said duct, said device comprising:

• an elongated member comprising an outer diameter sized for positioning within the breast duct and having an internal lumen for infusing a fluid into the breast duct and retrieving cellular material from within the branches;
• and
• a body for infusing fluid into said elongated member, said body comprising at least three openings for communicating with said internal lumen and dimensions such that said elongated member remains within the breast duct and capable of retrieving the cellular material from within the branches of the duct being lavaged after said elongated member has been positioned within said duct and said body is free of external support from a practitioner or assistant.

A ductal access device for accessing a breast duct and collecting cellular material from within the duct, said device comprising:

• a single elongated member comprising an outer diameter sized for positioning within the breast duct and an inner diameter for introducing fluid into the duct and receiving cellular material from within the duct;
• and
• a manifold hub for receiving cellular material from the breast duct carried by the elongated member, said manifold hub comprising at least three openings in communication with said elongated member and an inner diameter that is greater than the inner diameter of said elongated member.

A ductal access device comprising:

• a hub comprising an internal elongate manifold and at least three openings;
• and
• an elongated member comprising a distal end including an atraumatic tip, a proximal end, a single lumen in communication with said hub openings and extending between said distal and proximal ends, and dimensions which permit introduction of the distal end through a ductal orifice and positioning a distal end of said elongated member distal to a ductal sphincter and proximal a first bifurcation in a human breast duct.
