Catheter, apparatus and method for therapeutic embolization

摘要

The invention relates to an apparatus and a method for the therapeutic embolization of an aneurysm ( 1 ) as well as to a catheter. A plugging material ( 2 ) is injected via a catheter ( 5 ) inserted into the aneurysm ( 1 ). During the injection, the spatial position of an active locator ( 3 ), such as a magnetic field sensor for example, which is fitted to the tip of the catheter ( 5 ) is observed by a locating device ( 8, 9 ). If emergence of the catheter tip from the aneurysm ( 1 ) is detected by a monitoring unit ( 7 ), said monitoring unit stops the further supply of plugging material to the catheter ( 5 ).
