INTRODUCTION Long side-firing microwave (MW) arrays can deliver energy uniformly over its length without the need for intimate endocardial contact. We hypothesize that a novel 6 Fr 20 mm long percutaneous high-efficiency MW antenna array ablation catheter can rapidly create long, continuous, and transmural linear ablation lesions. METHODS AND RESULTS(More)
INTRODUCTION The biophysical properties of microwave electromagnetic radiation suggest that it may be an alternative to radiofrequency (RF) energy for ablation of arrhythmias resistant to treatment using RF ablation. METHODS AND RESULTS The aim of this study was to characterize lesions produced using simple element designs in a blood superfused ovine(More)
We present a reactive navigation algorithm for safe operation of hospital beds in dynamic environments. The proposed navigation is implementation efficient in the sense that it does not require any measurements from the velocities, shapes, dimensions or orientations of the obstacles. Furthermore, it is applicable for a variety of real world scenario where(More)
We present a novel design of an intelligent robotic hospital bed, named Flexbed, with autonomous navigation ability. The robotic bed is developed for fast and safe transportation of critical neurosurgery patients without changing beds. Flexbed is more efficient and safe during the transportation process comparing to the conventional hospital beds. Flexbed(More)
We present a novel motorized semi-autonomous mobile hospital bed guided by a human operator and a reactive navigation algorithm. The proposed reactive navigation algorithm is launched when the sensory device detects that the hospital bed is in the potential danger of collision. The semi-autonomous hospital bed is able to safely and quickly deliver critical(More)
The paper proposes a novel target following solution for an electric powered hospital bed. First, an improved real-time decoupling multivariable control strategy is introduced to stabilize the overall system during its operation. Environment laser-based data are then collected and pre-processed before engaging a neural network classifier for target(More)
We present a reactive navigation algorithm which ensures the safety of the hospital beds in the dynamic environments. The proposed navigation algorithm allows the hospital beds to avoid en-route obstacles with an efficient easy-to-compute sliding mode obstacle avoidance strategy when an obstacle is nearby, and move towards the target location at maximum(More)
