Methods and devices for obtaining and assaying mammary fluid samples for evaluating breast diseases, including cancer
First Claim
1. A sample collection device for collecting a biological sample from a mammary organ of a patient, comprising:
- a breast engaging member constructed of a non-porous material sized and dimensioned to receive at least a nipple portion of a breast of said patient and form a suction seal therewith;
a solid phase sample collection medium in fluid connection with said breast engaging member for receiving a sample of expressed breast fluid; and
vacuum pump means in gaseous connection with said breast engaging member for generating negative pressure through the breast engaging member to facilitate breast fluid expression, wherein said solid phase sample collection medium is selected from the group consisting of microscopic glass slides, capillary tubes, collection tubes, columns, micro-columns, wells, plates, membranes, filters, resins, inorganic matrices, beads, particulate chromatographic media, plastic microparticles, latex particles, coated tubes, coated templates, coated beads, coated matrices, or a combination thereof.

Abstract
Non-invasive methods are provided for obtaining biological samples of mammary fluid or mammary fluid components by administering oxytocin to a patient to stimulate expression of mammary fluid. During or after mammary fluid expression, a biological sample is collected in the form of whole mammary fluid, whole cells or cellular components, other selected liquid or solid fractions of the mammary fluid, purified or bulk proteins, glycoproteins, peptides, nucleotides or other desired Constituents of mammary fluid. Methods and kits are also provided for determining the presence or amount of a breast disease marker in biological samples of mammary fluid or mammary fluid components obtained according to the above sample collection methods. Also provided within the invention are novel breast pump and breast pump adapter devices which incorporate a solid phase sample collection medium integrated within the breast pump or adapter or otherwise fluidly connected therewith. These devices collect a sample of expressed breast fluid by contacting the fluid with a solid phase sample collection medium while the pump or adapter is applied to the breast.
