Zero-pressure balloon catheter and method for using the catheter

摘要

A safety catheter includes a shaft. The shaft has a proximal shaft portion having a proximal end, a distal tip portion defining a junction with the proximal shaft portion, a fluid drain lumen, and a balloon inflation lumen. The fluid drain lumen defines a distal fluid drain opening at the distal tip portion distal of the junction and a proximal fluid drain opening adjacent the proximal end and fluidically connected to the distal fluid drain opening. A hollow zero-pressure balloon is disposed at the junction and has an interior fluidly connected to the balloon inflation lumen, a distal leg fixedly secured to the distal tip portion, and a proximal leg temporarily secured to the proximal shaft portion.
