  • Patent number: 9173713
    Abstract: A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter. The present embodiment further contemplates a robotic surgical method for the articulation of a steerable catheter wherein an input device is manipulated to communicate a desired catheter position to a control computer and motor torque commands are outputted to an instrument driver.

  • Patent number: 8927441
    Abstract: Methods of forming rutile titanium dioxide comprise exposing a transition metal (such as V, Cr, W, Mn, Ru, Os, Rh, Ir, Pt, Ge, Sn, or Pb) to an atmosphere consisting of oxygen gas (O2) to produce an oxidized transition metal over an unoxidized portion of the transition metal. Rutile titanium dioxide is formed over the oxidized transition metal by atomic layer deposition. The oxidized transition metal is sequentially exposed to a titanium halide precursor and an oxidizer. Other methods include oxidizing a portion of a ruthenium material to ruthenium(IV) oxide using an atmosphere consisting of O2, nitric oxide (NO), or nitrous oxide (N2O); and introducing a gaseous titanium halide precursor and water vapor to the ruthenium(IV) oxide to form rutile titanium dioxide on the ruthenium(IV) oxide by atomic layer deposition. Some methods include exposing transition metal to an atmosphere consisting essentially of O2, NO, and N2O.
