Abstract

There is to be provided a catheter with the aid of which presentation of 3D ultrasound images is possible in a simple manner. The catheter possesses, approximately at its tip, an ultrasound emitter (6) with the aid of which an ultrasound cross-sectional image can be produced. Localisation for 3D imaging is possible by means of an RF coil (8) in the region of the tip of the catheter (1). There may furthermore be a balloon (2) for dilation of vessels. <IMAGE>

Description

Die Erfindung betrifft einen Katheter zur Einführung in ein Gefäß. Katheter dieser Art werden z. B. zum Aufweiten von Eng­ stellen in Blutgefäßen mit Hilfe eines aufblasbaren Ballons verwendet. Ferner ist es möglich, mit Hilfe eines Katheters ein Kontrastmittel in ein Gefäß einzuspritzen.The invention relates to a catheter for introduction into a Vessel. Catheters of this type are e.g. B. to expand Eng put in blood vessels with the help of an inflatable balloon used. It is also possible to use a catheter inject a contrast medium into a vessel.

Der Erfindung liegt die Aufgabe zugrunde, einen Katheter zu schaffen, der es ermöglicht, in einfacher Weise an einem vor­ gegebenen Ort ein Ultraschallbild des Gefäßes, in das der Katheter eingeführt ist, anzufertigen.The invention has for its object to a catheter create that makes it easy to work on a front given location an ultrasound image of the vessel into which the Catheter is inserted to make.

Diese Aufgabe ist erfindungsgemäß gelöst durch die Merkmale des Patentanspruches 1.According to the invention, this object is achieved by the features of claim 1.

Einzelheiten der Erfindung ergeben sich aus den Unteransprü­ chen.Details of the invention emerge from the subclaims chen.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zei­ gen:The invention is based on one in the drawing illustrated embodiment explained in more detail. It shows gene:

Fig. 1 einen Katheter nach der Erfindung, und Fig. 1 shows a catheter according to the invention, and

Fig. 2 den Katheter gemäß Fig. 1 in einem Blutgefäß. Fig. 2 shows the catheter of FIG. 1 in a blood vessel.

In der Fig. 1 ist ein Katheter 1 dargestellt, der in ein Ge­ fäß eingeführt werden kann und an seinem distalen Ende einen aufblasbaren Ballon 2 für die Gefäßdilatation aufweist. Hierzu kann in einen Kanal 3 Druckluft eingeleitet werden. In einem Kanal 4 des Katheters 1 ist eine Leitung 5 geführt, die zu einem Ultraschallgeber 6 an der Spitze des Katheters 1 führt. Die Leitung 5 führt zu einem Ultraschallbildsystem 7, mit dem dreidimensionale Ultraschallbilder erzeugt und wie­ dergegeben werden können. Eine dreidimensionale Übersichtsdarstellung von Gefäßen kann bei der Katheterisierung direkt erfolgen, wenn zu den Ultraschall-Querschnittsbildern, die mit Hilfe des Ultraschallgebers 6 angefertigt werden, die zugehörigen Raumkoordinaten erfaßt und im Bildsystem einbe­ zogen werden. Hierzu ist im Bereich des Ultraschallgebers 6 eine HF-Spule 8 als Lokalisationsgeber angeordnet.In Fig. 1, a catheter 1 is shown, which can be inserted into a vessel and has at its distal end an inflatable balloon 2 for vascular dilatation. For this purpose, 3 compressed air can be introduced into a duct. A line 5 is guided in a channel 4 of the catheter 1 and leads to an ultrasound transmitter 6 at the tip of the catheter 1 . The line 5 leads to an ultrasound imaging system 7 , with which three-dimensional ultrasound images can be generated and reproduced. A three-dimensional overview of vessels can be made directly in the catheterization if the associated spatial coordinates are acquired for the ultrasound cross-sectional images that are produced with the aid of the ultrasound generator 6 and are included in the imaging system. For this purpose, an RF coil 8 is arranged in the area of the ultrasound transmitter 6 as a localization transmitter.

Die Fig. 2 zeigt ein Gefäß 9, in dem der Katheter 1 einge­ führt ist. Die aktuelle Position der Katheterspitze wird durch Einblendung einer Markierung ins aktuelle dreidimen­ sionale Ultraschallbild wiedergegeben. Es ist eine Pseudodar­ stellung des Katheters durch das jeweilige Zentrum des jewei­ ligen Ultraschall-Querschnittsbildes möglich, dessen Position durch die HF-Spule 8 erfaßt wird. Fig. 2 shows a vessel 9 , in which the catheter 1 is inserted. The current position of the catheter tip is reproduced by inserting a marker into the current three-dimensional ultrasound image. It is a pseudodar position of the catheter through the respective center of the respective ultrasound cross-sectional image possible, the position of which is detected by the RF coil 8 .

Das Ultraschallbildsystem 7 kann auch in einem distalen Rönt­ genbildsystem 10, das in der Kardangiographie verwendet wird, integriert sein.The ultrasound imaging system 7 can also be integrated in a distal X-ray imaging system 10 which is used in cardangiography.
