Abstract
Catheter device comprising a catheter (2), particularly an intravascular catheter, for insertion into an organ or vessel of the human or animal body, with a device for ablation of the adjacent organ tissue or vessel tissue using high-frequency currents in the region of the tip of the catheter, a device (3, 11, 12, 18, 19, 23, 24) being integrated for capturing images of the organ or vessel in the region of the tip of the catheter (10, 17, 22).
Claims7
A catheter device, comprising:
- a catheter for inserting into an organ or vessel of a human or animal body, the catheter comprising:
- an ablation device having an ablation electrode arranged at a tip of the catheter for applying ablation to organ tissue or vessel tissue using high-frequency currents;
- an imaging device, fixedly arranged on the catheter, for recording an image of the organ tissue or the vessel tissue adjacent to the tip when the catheter is inserted;
- an ECG device, fixedly arranged on the catheter, for recording an ECG, the ECG device comprising an ECG electrode for acquiring ECG signals arranged at the tip of the catheter;
- a position detecting device comprising at least one position sensor arranged fixedly on the catheter near the catheter tip and a position signal receiver for detecting a current position or orientation of the catheter tip relative to a coordinate system of a three-dimensional spatial image generated on the basis of the ECG signals;
- and
- a common control device operatively connected to the imaging device, the ECG device and the position detecting device,
- wherein the ablation device, the ECG device and the imaging device are operatively connected to one another and configured to simultaneously apply the ablation, acquire the ECG signals, and record the image;
- and
- the common control device is configured to correlate the recorded image, the acquired ECG signals, and the current position of the catheter tip, respectively with one another, for orientation of the catheter device.
