UMD: Clamps designed for external (i.e., noninvasive) atraumatic compression of anatomic structures to provide temporary occlusion of a natural duct. These clamps are handheld, manual, instruments including two parts pivoted at the center or with spring-operated mechanisms, usually with padded distal ends. Dedicated external occlusion clamps are available to suppress urine circulation through the penis or to interrupt breathing through the nose.
