Remote magnetic actuation using a clinical scale system
Remote magnetic manipulation is a powerful technique for controlling devices inside the human body. It enables actuation and locomotion of tethered and untethered objects without the need for a local power supply. In clinical applications, it is used for active steering of catheters in medical interventions such as cardiac ablation for arrhythmia treatment and for steering of camera pills in th...
متن کاملSix-Degrees-of-Freedom Remote Actuation of Magnetic Microrobots
Existing remotely-actuated microrobots powered by magnetic coils far from the workspace exhibit a maximum of only five-degrees-of-freedom (DOF) actuation, as creation of a driving torque about the magnetization axis is not achievable. This lack of orientation control limits the effectiveness of existing microrobots for precision tasks of object manipulation and orientation for advanced medical,...
متن کاملInitial experience with remote catheter ablation using a novel magnetic navigation system: magnetic remote catheter ablation.
BACKGROUND Catheters are typically stiff and incorporate a pull-wire mechanism to allow tip deflection. While standing at the patient's side, the operator manually navigates the catheter in the heart using fluoroscopic guidance. METHODS AND RESULTS A total of 42 patients (32 female; mean age, 55+/-15 years) underwent ablation of common-type (slow/fast) or uncommon-type (slow/slow) atrioventri...
متن کاملMechanically-Stable Micro Assembly Using Magnetic Actuation
We have developed a new magnetic actuation process for assembling three-dimensional MEMS devices using hinged, surface micromachined structures. Electroplated magnetic material (Permalloy) is integrated with two types of hinged microstructures and the magnetic actuation process has been experimentally characterized. Under a given external magnetic field, the angular displacement of a hinged str...
متن کاملSURGICAL ROBOTICS AND INSTRUMENTATION Remote active magnetic actuation for a single-access surgical robotic manipulator
Purpose Magnetic coupling is one of the few strategies to transmit motion through physical obstacles. This approach can be applied to remotely control and manipulate medical devices/robots inside the human body preventing the need for dedicated incisions [1, 2]. The most straightforward approach to take advantage of magnetic coupling to control a medical device inside the human body consists in...
