摘要： A safety balloon catheter includes a stretch valve and a balloon catheter having a proximal catheter end, a balloon defining an interior to be inflated with an inflation fluid, an inflation lumen extending through the shaft to the interior and shaped to convey inflation fluid thereto and from, a second lumen parallel to the inflation lumen, and a balloon drainage port fluidically connecting the balloon interior to the second lumen. The hollow stretch valve is shaped to permit a fluid to pass therethrough and is positioned in the second lumen to at least partially slide therein such that, in a steady state, the stretch valve prevents the inflation fluid from passing through the drainage port and, in an over-inflated state, the distal sliding portion slides within the second lumen to permit the inflation fluid to pass through the drainage port and into the second lumen.

摘要： A safety catheter for draining a given fluid includes a hollow stretch valve and a flexible, multi-lumen, balloon drainage catheter having a proximal catheter end, a balloon defining a balloon interior to be inflated with an inflation fluid, a drain lumen. and a balloon drainage port fluidically connecting the balloon interior to the drain lumen. The hollow stretch valve is shaped to permit the given fluid to pass therethrough and is positioned in the drain lumen to at least partially slide therein such that, in a steady state, the stretch valve prevents the inflation fluid from passing through the drainage port, and, in a stretched state when the proximal catheter end is stretched, the distal sliding portion slides within the drain lumen to permit the inflation fluid to pass through the drainage port and into the drain lumen.
