Title: Anatomical Visualization With Electrically Conductive Balloon Catheter
Inventors: Lawrence J. Gerrans, Erhan H. Gunday, Lon Chu
Abstract: A balloon catheter for providing a 3-dimensional rendering of the interior of a cavity, the catheter system including a controller, a catheter connected to the controller and a balloon positioned on the catheter. The balloon includes a mesh having members extending longitudinally and circumferentially about the balloon where each member of the mesh has an electrical characteristic that changes as the member is deformed. The controller uses a measurement of the variable electrical characteristic to generate a three-dimensional rendering of an interior surface of the cavity, which can be rotating to different viewing angles.
