Abstract
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).
Claims14
A catheter (5) for the therapeutic embolization of aneurysms (1) by injection of a filling material (2) into the aneurysm (1) by way of an active locator (3) for the determination of the spatial position and/or orientation of the catheter (5).
An apparatus for the therapeutic embolization of aneurysms (1), comprising:
- a catheter (5) for injecting a filling material (2) into an aneurysm (1);
- a locating device (8, 9) and at least one active locator (3) fitted on the catheter (5), it being possible for the spatial position and/or orientation of the locator to be determined by the locating device (8, 9);
- a pump device (6) for controllably supplying filling material (2) to the catheter (5);
- a monitoring unit (7) connected to the locating device (8) and the pump device (6), which monitoring unit is designed to detect emergence of the catheter from the aneurysm during the injection of plugging material (2) into the aneurysm (1), and thereupon to stop the supply of plugging material.
A method of controlling the supply of a plugging material (2) to a catheter (5) during the therapeutic embolization of an aneurysm (1), comprising the steps:
- a) determining the position and/or orientation of the catheter via an active locator (3) fitted thereon;
- b) automatically stopping the supply of the plugging material (2) to the catheter (5) if emergence of the catheter from the aneurysm (1) is detected.
