Abstract

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 and has a radially self-expandable proximal section fixedly connected within the drain lumen by self-expansion, a flexible intermediate section longitudinally movable within the drain lumen, and a distal plug movably positioned in the drain lumen to prevent fluid from passing through the drainage port in a steady state and being slidably disposed within the drain lumen such that, in a stretched state when the proximal catheter end is stretched, the distal plug slides within the drain lumen to permit the inflation fluid to pass through the drainage port.
