Abstract: Presenting intravascular images and angiographic images co-registered on a display. As an imaging catheter is pushed through an occlusion, a center point of the catheter and an outline of the vessel wall can be displayed. A physician can see where the catheter is crossing the occlusion within the vessel. The physician can determine what path the catheter is taking the through occlusion. Methods include extending an imaging catheter through the occlusion, determining a location of a wall of the vessel relative to a center point of the catheter, obtaining a position of the catheter within a lumen of the vessel via angiography, and displaying the catheter crossing the occlusion by co-registering the location of the wall, the position of the catheter within the lumen, and the lumen on a display.

Abstract: The invention describes methods for safely delivering ablation energy to a tissue, e.g., thrombus, in need of ablation therapy. The method uses a catheter adapted for IVUS imaging, ablation, and impedance measurements to monitor the impedance of a tissue receiving ablation energy. In an embodiment, a user may view an IVUS image of the tissue with impedance measurements to determine if it is safe to deliver additional energy. In another embodiment, a processor is configured to determine if it is safe to deliver additional ablation energy based upon the impedance measurement.

Abstract: The invention generally relates to intravascular intervention catheters and provides catheters for performing an intravascular procedure that use a mechanism to control an operation at the end of the catheter. The mechanism can be used to steer the distal tip of the catheter from a controller at a proximal end of the catheter. The mechanism may include one or more pull wires extending along the catheter. The mechanism may optionally be manually or computer controlled.
