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.

Abstract: An interventional hysteroscope includes a shaft, an optical imaging element, an ultrasonic imaging element and a treatment element, such as an ablation needle. The shaft has a distal end, a proximal end, and a longitudinal axis therebetween, and the optical imaging element is disposed at the distal end of the shaft. The ultrasonic imaging element is also disposed at the distal end of the shaft and is configured to image along a laterally oriented image path. The treatment element is configured to be deployed from the shaft along a laterally oriented treatment path, and the imaging path and the treatment path intersect at an intersectional location spaced laterally away from the shaft. A display is configured to present both an optical image from the optical imaging element and an ultrasonic image from the ultrasonic imaging element and to present a marker on the ultrasonic image at a location corresponding to the intersectional location.

Abstract: The systems and methods described herein provide for a medical device insertable into the body of a living being having an imaging device with a layout that is adjustable from an undeployed layout, where the imaging device is insertable into the inner lumen of a medical device, to a larger deployed layout, where the imaging device preferably has a larger imaging aperture. The medical device can also include a flexible membrane coupled with or located on the distal end of the medical device. The flexible membrane can be expanded or inflated to create a spatial operating region for the deployed imaging device.

Abstract: A method and apparatus are described for locating a bifurcation of an artery. An elongated probe having a plurality of ultrasonic transducers, and an indicator attached to each transducer, is moved along the artery. Each transducer transmits ultrasound signals to the portion of the anatomy located underneath the transducer, and receives echo signals reflected from the portion of the anatomy. The echo signals are analyzed to detect any presence of blood flow. Each indicator generates output reference signals, for example light or sound, only if blood flow is detected by its associated transducer. The bifurcation is located by observing when a two-group pattern of output reference signals from the indicators merges into a single-group pattern of output reference signals. A single signaling device may be used instead of a plurality of indicators. Once the bifurcation is located, the probe may be switched into a measuring mode, in which the thickness of intima media is measured at the bifurcation.
