| 摘要 |
The atherectomy or thrombectomy device according to the invention comprises a rotary member composed of flexible filiform elements, which are joined by their two ands, the distal end and the proximal end; it contains no mechanical means for bringing said ands closer and the speed of rotation of the rotary member is sufficient, notably higher than 30,000 revs/min, to achieve the transversal expansion of the filiform elements under the effect of the centrifugal force. Preferably, the rotary member is constituted by a conduit, such as a conduit in polytetrafluoroethylene provided with one or two sets of longitudinal slits symmetricaly distributed over its periphery and defining flexible strips.
