Abstract: A method is disclosed for noninvasively obtaining intraductal fluid. The method includes the use of an intraductal fluid sampling device to contact the patient, provide compression, and deliver heat thereto according to predetermined cycle characteristics. The cycle characteristics, such as compression cycle times and compression rates, may be varied and controlled by a control circuit.

Abstract: Disclosed is a disposable patient interface for an intraductal fluid aspiration system. The interface has a flexible tubular distal member for contacting the patient, and a rigid proximal member forming a vacuum chamber therein. The rigid member has a vacuum aperture for communication with a source of vacuum. The flexible member preferably has a low modulus of elasticity and a high tear strength, such that it can be stretched to fit over a rigid support without rupture.

Abstract: A safety-sheathed blood sampling needle for use with a standard vacutainer. The needle is housed in a protective hollow body and held in place with a non-tensioned elastic band. The needle may be extended outside the cover for use without removing the cover assembly from the needle, and may be locked into the use position with one hand. Moving the needle into the use position tensions the elastic band. After the sample is taken, the needle is unlocked and retracted back into the cover by the elastic band. Upon such retraction, the element used to extend the needle is either concealed or disconnected to prevent accidental reuse of the needle.

Abstract: Disclosed is a disposable patient interface for an intraductal fluid aspiration system. The interface has a flexible tubular distal member for contacting the patient, and a proximal support portion forming a vacuum chamber therein. The support portion has a vacuum aperture for communication with a source of vacuum, and a retention structure for releasably mounting within a hand piece of an intraductal fluid aspiration system. The flexible member preferably has a low modulus of elasticity and a high tear strength, such that it can be stretched to fit over a rigid support without rupture.

Abstract: Disclosed is a method and apparatus for accomplishing a noninvasive screen for breast disease markers, including breast cancer markers and cytologically abnormal cells. Intraductal fluid is noninvasively aspirated using compression, heating and suction cycles. The removed sample is thereafter assayed for the presence of cytologically abnormal cells and/or one or more breast disease markers. In addition to the diagnostic applications of the disclosed method and apparatus, a therapeutic application is also contemplated wherein intraductal fluids are noninvasively aspirated using compression, heating and suction cycles to remove toxic buildups within the fluid.

Abstract: Disclosed is a disposable closed fluid loop for providing heat and compression to an intraductal fluid aspiration device. A plurality of bladders are configured to receive a pressurized inflation fluid, and to inflate in response thereto. The fluid is further configured to flow adjacent a heat exchanger, thereby receiving thermal energy, which it imparts to the bladders through conduction. Accordingly, the disclosed fluid loop provides heated inflation media to inflate a plurality of bladders to provide heat and compression to an intraductal fluid aspiration patient.

Abstract: Disclosed is an apparatus for noninvasive intraductal fluid aspiration. Intraductal fluid is noninvasively aspirated using compression, heating and suction cycles. The device is configured to provide a compression force, deliver heat, and apply a vacuum pressure to encourage the aspiration of patient fluid. The device includes an adjustable support and a movable wall for applying compression. Withdrawn fluid may be used either for diagnostic or therapeutic purposes.
