Abstract
Catheter device for performing atherectomy, comprising an atherectomy catheter, an OCT sensor, an IVUS sensor, position sensors and an image processing unit, which is embodied for creating combined 2D and/or 3D images based on the data of the sensors.
Claims18
A catheter device for performing an atherectomy in a patient, comprising:
- an atherectomy catheter having a rotating knife like cutter arranged in a tip area of the catheter;
- an OCT sensor arranged in a front part of the atherectomy catheter;
- an IVUS sensor arranged in the front part of the atherectomy catheter;
- a position sensor interoperated with the OCT sensor and the IVUS sensor;
- and
- an image processing unit connected with the OCT sensor, the IVUS sensor and the position sensor via a data bus, the image processing unit configured to create a combined image based on data from the sensors;
- wherein the position sensor is an electromagnetic sensor which comprises a transmit coil arranged in the atherectomy catheter and an external receiver coil, or an external transmit coil and a receiver coil arranged in the atherectomy catheter;
- and wherein the OCT sensor or the IVUS sensor is arranged on one side relative to a longitudinal axis of the atherectomy catheter.
