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.
