Abstract
A falloposcope is described, and a method of screening a patient for fallopian tube and/or ovarian cancer with the falloposcope. The falloposcope can perform optical imaging, including fluorescence imaging and/or optical coherence tomography (OCT), and optionally include a channel for a sampling wire, within a diameter of about 0.7 millimeter. The method includes inserting the falloposcope through a lumen of vagina, cervix, uterus, and fallopian tube so a tip of the falloposcope is in proximity to a first fallopian tube or ovary of the patient; providing fluorescence stimulus wavelength through an illumination fiber of the falloposcope while imaging light at fluorescence emission wavelength through a coherent fiber bundle to form fluorescence emissions images; and determining suspect tissue. Then the sampling wire is used to collect cells from the suspect tissue for karyotype and other analysis.
