Abstract:
This document provides catheters (e.g., urinary catheters) having safety mechanisms that indicate when a distal end of the device enters an intended cavity (e.g., a human's bladder) and is properly positioned, thereby preventing inflation of a retention balloon in an unintended location (e.g., the urinary canal). For example, safety urinary catheters and methods for using and inserting such safety urinary catheters are provided.
