A photodynamic treatment device treating a patient's cervix opening with light that causes selected tissue to fluoresce and imaging the tissue while the treatment is in progress without affecting the treatment.

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.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

A medical device may include a tool body and a handle. The handle may include a first body having a first coupling feature extending axially along the first body and a second body including a second coupling feature positioned within the first coupling feature. In a first orientation, the first body and second body may be rotatable and axially translatable relative to each other as a function of the first and second coupling features.

The present invention discloses access devices and methods to create an access channel for introduction of one or more working devices into an anatomical region. The access channel is created using a visualization modality that is later removed before inserting one or more working devices through the access channel. This allows the methods and devices of the present invention to be used even in small sized natural or surgically created insertion tracts leading to the anatomical region. The access channel can be made of a device such as a sheath, a guidewire, and an elongate device comprising a lumen. Examples of visualization modalities are endoscopes and body insertable ultrasound imaging devices. The working devices can be used to perform a variety of diagnostic, therapeutic, or preventive procedures. Endometrial ablation devices and procedures have been used as an example to describe various aspects of the present invention.

A speculum includes an upper bill, a lower bill downwardly of the upper bill, a yoke moveably joining the upper bill to the lower bill, and a ratchet to hold the upper bill and lower bill at a position relative to each other, the ratchet including teeth facing upwardly to selectively hold the upper bill and lower bill. When the ratchet is moved downwardly, the upper bill may pivot freely on the yoke. When the ratchet is moved upwardly, the upper bill is fixed against pivoting. In an example, the yoke includes a pivot about which the upper bill pivots when the ratchet allows and holds the upper bill in position against pressure on the upper bill. A latch prevents the yoke from being removed from the lower bill. Guides allow the upper bill move vertically on the lower bill through the yoke.

A stereo colposcope having variable linearity filter systems for both the excitation step and the suppression step, and can be used universally with any fluorescent compound or drug, as is the case of photodynamic diagnosis (PDD). The colposcope is a two-way colposcope because the treatment can be administered by an optical system or by a light-producing radio-frequency electrical current with a diathermic effect which facilitates photodynamic treatment. The colposcope produces ozone, which has an antiseptic effect when applied to the genital tract. A monitor provides for three-dimensional viewing through the use of two video cameras with the DLP (Digital Light Processing) and HDTV (High Definition Television) systems with the use of active lenses.
