APPARATUS FOR DILATATION OF HOLLOW TUBULAR ORGANS Russian patent published in 1997 - IPC

Abstract RU 2078589 C1

FIELD: medical engineering, surgical and endoscopic apparatus for treatment of pathologic constrictions of tubular organs: oesophagus, ureters, intestine, biliary ducts, blood vessels. SUBSTANCE: apparatus is made in form of current-conductive coaxial cable connectable to current supply source and high-frequency generator. Cable carries at its end working member in form of one or several loops forming some sort of basket made of alloy possessing shape memory effect, such as fluoroplast sheathing. EFFECT: enhanced reliability of dilatation, lower traumatism, possibility to conduct preliminary electric excision of coarse commissure-producing processes in constricted areas, shorter duration of manipulations, increased treatment efficiency due to combination of visual control with medicamentous treatment. 2 cl, 2 dwg
