BALLOON CATHETER PRESSURE RELIEF VALVE
A pressure relief apparatus for a balloon dilation catheter having a shaft with a dilation balloon attached to the distal end of the shaft and an inflation/deflation lumen for inflating and deflating the balloon includes a pressure relief port formed through the wall of the inflation/deflation lumen with a pressure relief member secured across the pressure relief port to form a fluid tight seal such that the fluid tight seal formed by the pressure relief member fails at a predetermined pressure to release pressure from the inflation/deflation lumen through the pressure relief port.
