    • 3D Ultrasound-Guided Motion Compensation System for Beating Heart Mitral Valve Repair 

      Yuen, Shelten G.; Kesner, Samuel Benjamin; Vasilyev, Nikolay; Del Nido, Pedro J.; Howe, Robert D. (Springer Verlag, 2008)
      Beating heart intracardiac procedures promise significant benefits for patients, however, the fast motion of the heart poses serious challenges to surgeons. We present a new 3D ultrasound-guided motion (3DUS) compensation ...

    • Bayesian change-point analysis for atomic force microscopy and soft material indentation 

      Rudoy, Daniel; Yuen, Shelten G.; Howe, Robert D.; Wolfe, Patrick J. (Wiley-Blackwell, 2010)
      Material indentation studies, in which a probe is brought into controlled physical contact with an experimental sample, have long been a primary means by which scientists characterize the mechanical properties of materials. ...

    • Bayesian Changepoint Detection Through Switching Regressions: Contact Point Determination in Material Indentation Experiments 

      Yuen, Shelten G.; Rudoy, Daniel Gregory; Howe, Robert D.; Wolfe, Patrick J. (Institute of Electrical and Electronics Engineers, 2007)
      Material indentation is a popular method for determining the mechanical properties of biomaterials. The basic premise of an indentation experiment is to physically displace the sample using an indenter that measures resistive ...

    • Force tracking with feed-forward motion estimation for beating heart surgery 

      Yuen, Shelten G.; Perrin, Douglas Paul; Vasilyev, Nikolay; Del Nido, Pedro J.; Howe, Robert D. (Institute of Electrical & Electronics Engineers (IEEE), 2010)
      The manipulation of fast moving, delicate tissues in beating heart procedures presents a considerable challenge to the surgeon. A robotic force tracking system can assist the surgeon by applying precise contact forces to ...

    • Haptic Noise Cancellation: Restoring Force Perception in Robotically-Assisted Beating Heart Surgery 

      Yuen, Shelten G.; Dubec, Karl-Alexander; Howe, Robert D. (Institute of Electrical and Electronics Engineers, 2010)
      Beating heart surgical methods have the potential to remove the need for the heart-lung machine and its attendant side effects, but must contend with the motion of the heart. Recent research in robotically-assisted ...

    • Quasiperiodic predictive filtering for robot-assisted beating heart surgery 

      Yuen, Shelten G.; Novotny, Paul Martin; Howe, Robert D. (Institute of Electrical and Electronics Engineers, 2008)
      Beating heart procedures promise significant health benefits to patients but the fast motion of the heart poses a serious challenge to the surgeon. Robotic motion synchronization to heart movements could facilitate these ...

    • Robotic Force Stabilization for Beating Heart Intracardiac Surgery 

      Yuen, Shelten G.; Yip, Michael C.; Vasilyev, Nikolay; Perrin, Douglas Paul; Del Nido, Pedro J.; Howe, Robert D. (Springer Verlag, 2009)
      The manipulation of fast moving, delicate tissues in beating heart procedures presents a considerable challenge to surgeons. We present a new robotic force stabilization system that assists surgeons by maintaining a constant ...

    • Robotic Motion Compensation for Beating Heart Intracardiac Surgery 

      Howe, Robert D.; Yuen, Shelten G.; Kettler, Daniel T.; Notovny, Paul M.; Plowes, Richard D. (SAGE Publications, 2009)
      3D ultrasound imaging has enabled minimally invasive, beating heart intracardiac procedures. However, rapid heart motion poses a serious challenge to the surgeon that is compounded by significant time delays and noise in ...

    • Robotic tissue tracking for beating heart mitral valve surgery 

      Yuen, Shelten G.; Vasilyev, Nikolay; Del Nido, Pedro J.; Howe, Robert D. (Elsevier BV, 2013)
      The rapid motion of the heart presents a significant challenge to the surgeon during intracardiac beating heart procedures. We present a 3D ultrasound-guided motion compensation system that assists the surgeon by synchronizing ...

    • A Robust Uniaxial Force Sensor for Minimally Invasive Surgery 

      Yip, Michael C.; Yuen, Shelten G.; Howe, Robert D. (Institute of Electrical and Electronics Engineers, 2010)
      This paper presents a novel, miniature uniaxial force sensor for use within a beating heart during mitral valve annuloplasty. The sensor measures 5.5 mm in diameter and 12 mm in length, and provides a hollow core to pass ...

    • Ultrasound Servoing of Catheters for Beating Heart Valve Repair 

      Kesner, Samuel Benjamin; Yuen, Shelten G.; Howe, Robert D. (Springer Verlag, 2010)
      Robotic cardiac catheters have the potential to revolutionize heart surgery by extending minimally invasive techniques to complex surgical repairs inside the heart. However, catheter technologies are currently unable to ...
