Abstract: An inflatable packaging bag formed of a plurality of independent air bags joined to one another by way of heat-sealing, having an air inlet through which compressed air is supplied to inflate the independent air bags. Each independent air bag is formed of a top four thin-sheet flexible layers including a top layer, a bottom layer, a top air-valve layer, and a bottom air-valve layer, having heat sealed seams that seal the layers, constituting an enclosed air chamber such that when some of the independent air bags are punctured, the other independent air bags work normally to continue to protect storage items put inside the inflatable packaging bag and surrounded by the independent air bags.

Abstract: A tool box includes a base and a cover which is pivotably connected to the base and has a magnetic member connected to an inside thereof so as to attract small pieces. A hanging member has a hook portion connected to a first end thereof so as to be attached to a user's belt and an engaging member is connected to the hook portion. A board has two ridges on a side thereof and the tool box is clamped between the two ridges. A hole is defined through the board and the engaging member is rotatably engaged with the tool box.

Abstract: This is a method for treating a patient diagnosed with atrial arrhythmia by forming a circumferential conduction block along a circumferential path of tissue in a pulmonary vein wall that circumscribes the pulmonary vein lumen and transects the electrical conductivity of the pulmonary vein such that conduction is blocked along the longitudinal axis of the vein wall and into the left atrial wall. The method is performed to treat a patient with a focal arrythmogenic origin along the pulmonary vein wall by either ablating the focal origin or by isolating the focal origin from the atrial wall with the circumferential conduction block. The circumferential conduction block is also formed in a pulmonary vein in order to bridge the adjacent ends of two linear lesions, wherein each linear lesion is formed to extend between the pulmonary vein and another adjacent pulmonary vein in a less-invasive "maze"-type procedure.
