CATHETER DEVICE COMPRISING A SEPARATING DEVICE FOR RETAINING MAGNETIC PARTICLES CONTAINED IN A FLUID AND PROTECTION DEVICE FOR A FUNCTIONAL ELEMENT

摘要

The invention relates to, amongst other things, a catheter device comprising a catheter (24) in which a rotating shaft (25) which is made at least partially from a magnetic material is arranged, and a separating device which contains an annular body (27) surrounding the rotating shaft and having a cavity containing a magnetic body (13'), the magnetic body being arranged downstream from a point at which the the shaft (25) exits the catheter (24) which it surrounds with respect to the direction of flow of the fluid through the catheter.
