Abstract
A medical instrument including a ductal access device comprising a low profile, ergonomic manifold hub usable to introduce fluids into a breast duct and collect ductal fluid samples including ductal epithelial cells and clumps of ductal epithelial cells from within a breast duct. The ductal access device also comprises an elongated access catheter having a distal end, one lumen and dimensions which permit introduction of the distal end through a ductal orifice so that a distal end of the catheter may be positioned distal to the ductal sphincter of a human breast. The medical instrument may also include and activate valve and a Nitinol introducer.
