    An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. Usually congenital , this vascular anomaly is widely known because of its occurrence in the central nervous system (usually as a cerebral AVM ), but can appear anywhere in the body.

    An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization

    Although the lesions can be notoriously hard to find, the patient usually is diagnosed by endoscopy. A new technique, pill enteroscopy, has been a major advance in diagnosis, especially in the small bowel which is difficult to reach with traditional endoscopy. With this technique a pill that contains a video camera and radio transmitter is ...

    APC involves the use of a jet of ionized argon gas directed through a probe passed through the endoscope.The probe is placed at some distance from the bleeding lesion, and argon gas is emitted, then ionized by a high-voltage discharge (approx 6kV). [1]

    A Storz endoscopy unit used for laryngoscopy exams of the vocal folds and the glottis Basil Hirschowitz , Larry Curtiss, and Wilbur Peters invented the first fiber optic endoscope in 1957. [ 18 ] Earlier in the 1950s Harold Hopkins had designed a "fibroscope" consisting of a bundle of flexible glass fibres able to coherently transmit an image.
