| 摘要 |
An embolisation device for promoting clot formation in a lumen comprises at least two segments (3,4), each segment (3,4) comprising a stem and a plurality of flexible bristles extending outwardly from the stem. The bristles have a contracted delivery configuration and a deployed configuration in which the bristles extend generally radially outwardly from the stem to anchor the device in a lumen. In the deployed configuration bristles of one segment (3) extend partially in a first longitudinal direction and the bristles of another segment (4) extend partially in a second longitudinal direction which is opposite to the first longitudinal direction. A flow restrictor (5) is located adjacent to a proximal end of the device and/or a flow restrictor (5') is located adjacent to the distal end of the device. |
