Therapeutic device
Abstract
Abstract Translated from English Un appareil d'induction de trombose dans un vaisseau sanguin sous jacent a une surface (14) d'un corps d'un etre humain ou d'un animal vivant comprend une electrode therapeutique (15, 21, 22, 23, 24) qui est suffisamment flexible pour epouser la forme de cette surface, et des moyens (17) pour maintenir l'electrode en contact avec la surface et pour restreindre le flux de sang s'ecoulant au travers du vaisseau sanguin pendant l'induction de trombose. Un courant continu passe par l'electrode jouant le role d'anode et d'une contre-cathode pour coaguler le sang dans le vaisseau sanguin adjacent a l'anode. L'appareil est utile pour traiter le saignement actif des varices de l'oesophage, l'electrode (15) pouvant avoir la forme generale d'un tube de tamponnement oesophagien de Fengstaken-Blakemore. An apparatus for inducing thrombosis in a blood vessel underlying a surface (14) of a body of a human or living animal includes a therapeutic electrode (15, 21, 22, 23, 24) which is flexible enough to conform to the shape of this surface, and means (17) for holding the electrode in contact with the surface and for restricting the flow of blood flowing through the blood vessel during induction of thrombosis. A direct current passes through the electrode acting as an anode and a counter-cathode to coagulate the blood in the blood vessel adjacent to the anode. The device is useful for treating active bleeding from varicose veins in the esophagus, the electrode (15) possibly having the general shape of a Fengstaken-Blakemore esophageal tamponade tube.
