Abstract
A catheter apparatus with occlusion and flow diverting valve means for controlling the flow of fluid into a tube including a conduit to lead fluid into cylindrical tube, a bag-like member made of resilient material and arranged to close an opening of the top of the conduit, a valve means provided on the conduit and a connecting means to connect the bag-like member and the valve means. Settling this apparatus in the cylindrical tube, when fluid is forced to flow into the bag-like member through the conduit, the bag-like member expands, whereby the cylindrical tube is closed and the valve means is opened to flow fluid out of the conduit.
