Patent number: 8412307Abstract: The present invention is a device localization system that uses one or more ultrasound reference catheters to establish a fixed three-dimensional coordinate system within a patient's heart using principles of triangulation. The coordinate system is represented graphically in three-dimensions on a video monitor and aids the clinician in guiding other medical devices, which are provided with ultrasound transducers, through the body to locations at which they are needed to perform clinical procedures. In one embodiment of a system according to the present invention, the system is used in the heart to help the physician guide mapping catheters for measuring electrical activity, and ablation catheters for ablating selected regions of cardiac tissue, to desired locations within the heart.Type: GrantFiled: September 9, 2005Date of Patent: April 2, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: N. Parker Willis, Alex Brisken, Jinglin Zeng, Marsha Hurd

Patent number: 7633502Abstract: Methods and systems are provided for generating graphical representations of orifices and vessels. One method comprises generating a representation of the surface (e.g., an endocardial surface) within a coordinate system, and laterally moving the distal end of an elongated probe within an orifice (e.g., a valve or a vessel ostium) associated with the surface. The method further comprises defining line segments within the coordinate system while the probe distal end is moved within the orifice, wherein each of the line segments represents the probe distal end. The method further comprises defining intersection points within the coordinate system, wherein each of the points represents an intersection of one of the line segments and the surface representation. Lastly, the method comprises graphically generating a representation of the orifice based on the intersection points, e.g., by forming the orifice representation around the intersection points.Type: GrantFiled: May 19, 2004Date of Patent: December 15, 2009Assignee: Boston Scientific Scimed, Inc.Inventors: N. Parker Willis, Ren-Her Hwang, Jinglin Zeng

Patent number: 6950689Abstract: The present invention is a system and method for graphically displaying a three-dimensional model of a region located within a living body. A three-dimensional model of a region of interest is displayed on a graphical display. The location in three-dimensional space of a physical characteristic (e.g. a structure, wall or space) in the region of interest is determined using at least one probe positioned within the living body. The graphical display of the model is deformed to approximately reflect the determined three-dimensional location of the physical characteristic. Preferably, the probe or probes are moved throughout the region of interest so as to gather multiple data points that can be used to increase the conformity between the graphical display and the actual region of interest within the patient.Type: GrantFiled: August 3, 1998Date of Patent: September 27, 2005Assignee: Boston Scientific Scimed, Inc.Inventors: N.
