Abstract: Various embodiments provide systems, methods, devices, and instructions for performing simultaneous localization and mapping (SLAM) that involve initializing a SLAM process using images from as few as two different poses of a camera within a physical environment. Some embodiments may achieve this by disregarding errors in matching corresponding features depicted in image frames captured by an image sensor of a mobile computing device, and by updating the SLAM process in a way that causes the minimization process to converge to global minima rather than fall into a local minimum.

Abstract: The present disclosure describes devices and methods for treating disorders in a hollow body organ by ablating the tissue therein. At least one set of bipolar electrodes is deployed in the hollow body organ to contact the inner wall of the organ. In the deployed position, each positive electrode is positioned in a location substantially opposite each negative electrode. The tissue contact areas of the positive and negative electrodes are substantially the same and the electrodes are separated from one another by a distance of at least 10 times the width of each of the electrodes. The electrodes thereby produce lesions that are substantially identical to one another and also similar to those produced with monopolar electrodes. The electrodes are used to produce an ablation pattern that can electrically isolate regions of the hollow body organ, thereby treating the disorder(s).
