Embodiment Construction

[0015] The proposed device and the corresponding method will be illustrated below by means of a planning example using, for example, a TAVI catheter. The TAVI catheter is approximately 7 mm thick and requires relatively large radii of curvature for the vessels involved due to its rigidity. For this planning, a CT angiography dataset from the groin to the aortic arch was recorded. In the proposed device, said volume data set is stored in a data memory 1 . The data set with blood vessels clearly marked by angiography is presented to the user via the visualization module 2 on the screen 3 . The user can select the blood vessel on the screen through which the catheter's path should later pass. Usually, this takes place via the interaction module 5 by means of a graphical input device such as a mouse 4 . Thereby, blood vessels can be selected, for example, by mouse clicks in a known manner.

[0016] In an advantageous embodiment, the user can also set the starting point (eg tra...

Abstract

A device and a method for planning an endovascular procedure are proposed. A medical instrument, particularly a catheter, is introduced into a vessel and is guided to its place of application via the vessel. Vessel diameters and bend radiuses along a plotted vessel course are automatically determined from the volume data set of the medical imaging and compared with a maximum diameter and minimum bend radius of the medical instrument planned for use. Points or regions within the plotted vessel course which have too low a vessel diameter or bend radius are subsequently highlighted in color in an image display of the vascular tree or vessel course. The user immediately detects critical areas and can if necessary change his or her plan or resort to an instrument with different geometric data. The method and the device make planning the endovascular procedure possible even for inexperienced users.

Description

technical field [0001] The present invention relates to a device and a method for planning an intravascular procedure, in which a medical device, in particular a catheter, is introduced into a blood vessel and passed through the blood vessel to an application area. Background technique [0002] In various arterial and venous diseases, the treatment can be effected endovascularly, that is to say through blood vessels. The type of application is varied and includes, for example, in abdominal or thoracic aortic aneurysms, in aneurysms of cerebral arteries, in carotid or coronary vascular stenosis or in aortic / mitral insufficiency or minimally invasive Stent grafts (Stentkrafteinbringung) are introduced in valve replacements (eg TAVI). Preoperative planning is required during these minimally invasive endovascular procedures and is often performed by computed tomography (CT) or magnetic resonance imaging (MRT). [0003] In many minimally invasive applications catheters are used...
