Abstract
The present invention generally relates to methods for removing plaque from a vessel. The method can involve obtaining a first image of a blood vessel using a first imaging modality, obtaining a second image of the blood vessel using a second imaging modality, and coregistering the first and second images, thereby generating a coregistered data set. The method can further involve inserting an atherectomy catheter into the blood vessel and removing plaque from the vessel with the atherectomy catheter based on plaque identified in the coregistered set of data.
Claims21
A method for removing plaque in a vessel, the method comprising:
- obtaining a first set of image data corresponding to a blood vessel using a first imaging modality;
- obtaining a second set of image data corresponding to the blood vessel using a second imaging modality;
- coregistering the first and second sets of image data, thereby generating a coregistered set of image data;
- identifying vessel plaque in the coregistered set of image data;
- inserting a plaque-removal device into the blood vessel;
- and
- removing plaque within the vessel based on plaque identified in the coregistered set of image data.
