    • A 4-DOF Robot for Positioning Ultrasound Imaging Catheters 

      Loschak, Paul; Tenzer, Yaroslav; Degirmenci, Alperen; Howe, Robert D. (American Society of Mechanical Engineers, 2015)
      In this paper we present the design, fabrication, and testing of a robot for automatically positioning ultrasound imaging catheters. Our system will point ultrasound (US) catheters to provide real-time imaging of anatomical ...

    • Algorithms for Automated Pointing of Cardiac Imaging Catheters 

      Loschak, Paul; Brattain, Laura; Howe, Robert D. (Springer Science + Business Media, 2014)
      This paper presents a modified controller and expanded algorithms for automatically positioning cardiac ultrasound imaging catheters within the heart to improve treatment of cardiac arrhythmias such as atrial fibrillation. ...

    • Algorithms for Automatically Pointing Ultrasound Imaging Catheters 

      Loschak, Paul; Brattain, Laura; Howe, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2017-02)
      A system for automatically pointing ultrasound (US) imaging catheters will enable clinicians to monitor anatomical structures and track instruments during interventional procedures. Off-the-shelf US catheters provide high ...

    • Assured Safety Drill With Bi-Stable Bit Retraction Mechanism 

      Loschak, Paul; Xiao, Kechao; Pei, Hao; Kesner, Samuel Benjamin; Thomas, Ajith; Walsh, Conor (ASME, 2013-08-04)
      A handheld, portable cranial drilling tool for safely creating holes in the skull without damaging brain tissue is presented. Such a device is essential for neurosurgeons and mid-level practitioners treating patients with ...

    • Automated pointing of cardiac imaging catheters 

      Loschak, Paul; Brattain, Laura; Howe, Robert D. (2013)
      Intracardiac echocardiography (ICE) catheters enable high-quality ultrasound imaging within the heart, but their use in guiding procedures is limited due to the difficulty of manually pointing them at structures of interest. ...

    • Compensation for unconstrained catheter shaft motion in cardiac catheters 

      Degirmenci, Alperen; Loschak, Paul; Tschabrunn, Cory; Anter, Elad; Howe, Robert D. (IEEE, 2016)
      Abstract— Cardiac catheterization with ultrasound (US) imaging catheters provides real time US imaging from within the heart, but manually navigating a four degree of freedom (DOF) imaging catheter is difficult and requires ...

    • Instrument Tracking and Visualization for Ultrasound Catheter Guided Procedures 

      Brattain, Laura; Loschak, Paul; Tschabrunn, Cory Michael; Anter, Elad; Howe, Robert D. (Springer Science + Business Media, 2014)
      We present an instrument tracking and visualization system for intra-cardiac ultrasound catheter guided procedures, enabled through the robotic control of ultrasound catheters. Our system allows for rapid acquisition of ...

    • Motion Compensation of Cardiac Catheters: Steering and Control 

      Loschak, Paul M. (2016-08-24)
      Advanced navigation of steerable flexible manipulators can enable a wider range of surgical procedures and interventions to be done less invasively. The techniques described here were designed for applications in cardiac ...

    • A robotic system for actively stiffening flexible manipulators 

      Loschak, Paul; Burke, Stephen; Zumbro, Emiko; Forelli, Ali Ryan; Howe, Robert D. (2015)
      A system for actively changing the stiffness of a long, thin, flexible robotic manipulator has been designed for cardiologists to use in a range of diagnosis and treatment procedures. Low-stiffness manipulators, such as ...
