  • Anatomical visualization with electrically conductive balloon catheter
    Patent number: 9968300
    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.
    Type: Grant

  • Electrically conductive balloon catheter
    Patent number: 9687196
    Abstract: A balloon catheter having a mesh affixed thereto. The mesh is formed having members extending longitudinally and circumferentially about the balloon into columns and rows respectively. Each member of the mesh has a resistance or impedance that changes as the member is deformed such that, when the member comprises a length (L) a measured resistance or impedance will be different than when the member comprise a length (L1) where L1 is greater than L.
