流体の中に含有されている磁性粒子を保持するための分離デバイスを含むカテーテルデバイスおよび機能要素のための保護デバイス

摘要

The present invention relates in particular to a catheter device, which includes a catheter 24 in which a rotating shaft 25 at least partially made from a magnetic material is disposed, the catheter device being a separation device. And the separation device contains an annular body 27, the annular body 27 surrounding the rotating shaft and having a cavity containing a magnetic body 13 ' The body is positioned downstream from the point where the shaft 25 exits the catheter 24 surrounding the shaft 25 with respect to the direction of fluid flow through the catheter.
