The Galileo Disposable Hysteroscopes are endoscopes intended for visualization of the cervical canal and uterine cavity for diagnostic and surgical procedures during gynecological procedures. The Hysteroscope diagnostic indications include abnormal uterine bleeding, infertility and pregnancy wastage, evaluation of abnormal hysterosalpingogram, intrauterine foreign body, amenorrhea and pelvic pain. The Hysteroscope is indicated for surgical procedures such as directed biopsy, removal of submucous fibroids and large polyps, submucous myomectomy, transection of intrauterine adhesions and septa and endometrial ablation.
The Galileo Disposable Hysteroscopes are a line of disposable endoscopes based on existing endoscope technology. The Galileo Disposable Hysteroscopes will be available in several sizes and lengths. The Galileo Disposable Hysteroscopes are fiber optic design endoscopes that are offered in disposable configurations only. Fiberoptic design endoscopes function by light being transmitted from a standard external high intensity light source through optical fibers to the distal tip of the endoscope. The image of the target is then transmitted from the distal end via an objective lens and a fiberoptic imaging bundle to a proximal eyepiece. The image can be viewed directly or it may be transmitted through a video camera to a video monitor. The Disposable Hysteroscopes are offered with a coupler that includes a light source which is provided by Galileo Electro-Optics Corporation. The Galileo coupler is compatible only with the Galileo Disposable Hysteroscopes and the other cleared commercially available Galileo endoscopes.
