摘要： A safety catheter includes a flexible, multi-lumen shaft having an outer diameter, a distal tip, a proximal catheter end with a drain end and a proximal inflation end. The multi-lumen shaft defines a drain lumen, a distal hollow balloon portion, at least one inflation lumen, and a drainage port. A hollow stretch valve is coaxially disposed in the drainage lumen, has a fixed portion within the drainage lumen just proximal of an increased stretching portion, and prevents fluid from passing through the drainage port in a steady state. The stretch valve has a sliding portion slidably disposed within the drainage lumen such that, in a stretched state when the proximal catheter end is stretched, the sliding portion slides within the drainage lumen to permit fluid to pass through the balloon drainage port and/or inner wall of the catheter.

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.
