Patent ID: 7785261

Claim:
A catheter device for treatment of a vessel blockage of a patient under an image monitoring, comprising: a pincer-type catheter which treats the vessel blockage, said pincer-type catheter arranged at a tip of the catheter device, and including pincers configured to push away plaque of the vessel blockage in stages to remove the vessel blockage; a position sensor system which is arranged in the catheter device for locating a position of the catheter device within the patient; an OCT catheter and an IVUS catheter which are arranged in the catheter device for the image monitoring; an image fusion unit coupled to the OCT catheter, the IVUS catheter and the position sensor system; said image fusion unit configured to combine image data from the OCT catheter of a local area to the vessel blockage and image data from the IVUS catheter of a remote area to the vessel blockage into a combined OCT/IVUS image; an X-ray device configured to combine or overlay the combined OCT/IVUS image with image data of the patient from the X-ray image device, to register the OCT/IVUS image; wherein said pincers include an opening through which the OCT catheter and IVUS catheter are configured to pass to record an image in advance of said pincers, said opening being formed between an upper half and a lower half of the pincers; and wherein the catheter device is configured to rotate and simultaneously pull or push the OCT catheter or the IVUS catheter through the opening, to perform a three-dimensional imaging.
