LOW PROFILE VALVE

摘要

An occlusion device for occluding a body conduit including an elongate tubul ar shaft having an inflatable balloon disposed near the elongate shaft distal e nd and a proximal seal having a sufficiently small profile to allow a second catheter to pass over the distal occlusion device while the inflatable ballo on remains uninflated. One occlusion device includes an elongate fluid displacement rod within the occlusion device elongate shaft, providing both a fluid pressure source and a seal. The elongate rod can be rapidly advanced a nd retracted, providing rapid and controlled inflation and deflation of the distal balloon. Also provided are alignment devices for aligning inflation fluid sources with occlusion device tubular proximal ends which can inject fluid through the device into the distal balloon.
