Устройство для ликвидации закупорок в сосудах или в малых отверстиях в теле человека, содержащее вращающийся наконечник 16 аблятора (ablator), который направляют к месту закупорки в конфигурации с уменьшенным диаметром, расширяют и вращают для устранения этой закупорки и сжимают для удаления устройства из тела человека. Катушку 16 абразивного наконечника с изменяемым объемом в одном воплощении приводят в действие поршнем, находящимся внутри катушки. Пара 28, 50 муфт присоединена к концам этой катушки 20, а поршень осуществляет относительное продольное осевое перемещение этих муфт и соответствующих концов катушки. Когда эти концы наконечника катушки перемещают таким образом, происходит расширение и сжатие диаметра наконечника катушки. В другом воплощении это расширение наконечника катушки активируют расширяемыми и сжимаемыми сильфонами, расположенными внутри катушки. В другом воплощении это расширение и сжатие наконечника катушки осуществляют движением в направлении продольной оси внутренней катушки, присоединенной к одному концу наконечника катушки, внутри внешней катушки , присоединенной к другому концу наконечника.

A device for eliminating obstructions in vessels or in small openings in the human body, containing a rotating tip 16 of the ablator, which is directed to the site of obstruction in a configuration with a reduced diameter, expands and rotates to eliminate this obstruction and compresses to remove the device from the human body. The coil 16 abrasive tip with variable volume in one embodiment is driven by a piston inside the coil. A pair of 28, 50 couplings is attached to the ends of this coil 20, and the piston performs a relative longitudinal axial movement of these couplings and the corresponding ends of the coil. When these ends of the coil tip are moved in this way, the diameter and diameter of the coil tip expands and contracts. In another embodiment, this expansion of the coil tip is activated by expandable and compressible bellows located inside the coil. In another embodiment, this expansion and compression of the coil tip is carried out by moving in the direction of the longitudinal axis of the inner coil, attached to one end of the coil tip, inside the outer coil, attached to the other end of the tip.
