Patent number: 9259559Abstract: 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. A splash guard is positioned across the pressure relief port, the splash guard being formed from a fluid permeable body defining a plurality of flow passages therethrough, whereby the splash guard partially obstructs fluid flow through the pressure relief port to prevent a direct uncontrolled release of the fluid from the pressure relief port.Type: GrantFiled: February 6, 2015Date of Patent: February 16, 2016Assignee: FUTUREMATRIX INTERVENTIONAL, INC.Inventor: Lanny R.
