A method and apparatus for positioning a camera to capture images inside a body cavity of a patient during a medical procedure is disclosed. The apparatus includes an insertion tube, a plurality of connected linkages extending from a distal end of the insertion tube, each linkage having a threaded actuator received on a threaded end of a drive shaft extending between the threaded actuator and a proximal end of the insertion tube. The apparatus also includes a camera disposed at a distal end of the plurality of connected linkages. Each connected linkage has at least one associated movement actuated by movement of the threaded actuator in response to rotation of the drive shaft, the associated movements of the connected linkages together operable to facilitate positioning of the camera within the body cavity of the patient.

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.
