Abstract
A falloposcope intended for use with a hysteroscope to access, image, and collect samples from a patient's fallopian tube includes a cannula having an angled tip oriented to engage a fallopian tube os when the cannula is transcervically introduced to a patient's uterus through the hysteroscope. The catheter has a distal viewing tip configured to be advanced from a distal end of the cannula into the patient's uterus through a cervical os. A viewing chamber has a wide proximal end attached to the distal viewing tip of the catheter, and the viewing chamber is at least partially transparent and typically tapers in a distal direction to provide a clear viewing zone for the endoscope as well as atraumatic advancement into the fallopian tube.
