Abstract
A multipurpose tamponade and thrombosclerotherapy tube for the endoscopic thrombosclerosis of esophageal varices and which permits effective gastric lavage at the same time that controlled esophageal tamponade is taking place. The invention comprises a tube-balloon assembly which includes a transparent polyvinyl tube of predetermined dimensions having a pair of opposing windows located at a spaced distance from its distal end. A latex balloon is mounted over the tube at an intermediate position and connected to a manometer by means of a polyvinyl catheter. The proximal end of the outer tube is connected to an irrigating system and a large siphon for gastric drainage. A metal cap fits snugly into the proximal outer tube and comprises a copper member having a latex nipple diaphragm mounted thereover which provides a seal and yet includes a small opening allowing passage of an endoscope.
