Embodiment Construction

[0051] exist figure 1 The free first end E1 of the conduit shown is rounded. In the region of this first end E1 , the catheter is equipped with a radiation source 1 with which beta or gamma radiation can be generated for therapeutic purposes.

[0052] The position display element is marked with the reference number 2 . In this case, for example, three coils are arranged offset by 90° relative to each other in the X, Y and Z directions. However, it is also possible to arrange the coils relative to each other at other offset angles (eg 60°). Instead of coils, other suitable transmitting or receiving elements, such as permanent magnets or ultrashort-wave converters, can also be arranged with an offset corresponding to the direction of the magnetic flux. Reference numeral 3 designates an inflatable balloon.

[0053] In the tube 4 of the catheter is placed a core 5 rotatable about the axis of the catheter, on whose second end E2 an NMR device 6 is arranged. The NMR device 6 is...

Abstract

The invention relates to a catheter for brachytherapy having a radiation source for generating beta or gamma rays. So that the catheter can be positioned as precisely as possible it is inventively proposed to provide an NMR device in the area of a free end of the catheter for generating and detecting NMR signals created through magnetic resonance of the atomic nucleus.

Description

technical field [0001] The present invention relates to a catheter. The invention also relates to a catheter device, and an imaging diagnostic device comprising the catheter or the catheter device. Background technique [0002] One such catheter is disclosed in WO 97 / 25102A1. In practice, the problem arises when using known catheters that the radiation source is often not positioned with the required accuracy in the blood vessel to be treated. [0003] In order to eliminate this disadvantage, known catheters are combined with imaging devices. In this case, for example, there are devices which generate images on the basis of ultrasound signals. Such a device is known for example from EP0885594. [0004] US 6,377,048 B1 and US 6,704,594 B1 describe a catheter with an NMR device for generating and acquiring NMR signals induced by magnetic resonance of atomic nuclei. The NMR device makes it possible to create two-dimensional or three-dimensional images of the tissue surroun...
