ARTERIAL TAMPONADE DEVICE AND METHOD

摘要

An arterial tamponade device is expandable between a collapsed condition and an expanded position and has opposite ends, with an enlarged pad at one or both ends. The device is inserted into a body cavity in its collapsed condition and is released at a predetermined location so that opposite ends of the device are biased away from one another and apply pressure to opposite wall regions of the body cavity before the device is fully expanded, with a pad at one end positioned to apply pressure to a predetermined tissue area which includes a blood vessel so as to occlude or partially occlude the vessel and reduce or cut off blood flow to the body cavity. The pad may have a bulbous projection configured to engage a depression of a body cavity wall region in which a blood vessel is located.
