Abstract
A balloon catheter having a flexible tubing containing a plurality of lumens and an inflatable balloon adjacent its distal end is connected to a coaxial unit incorporating a syringe at its proximal end. The syringe applies fluid through at least one of the lumens to inflate the balloon. Other lumens are connected to fluid sources or electrical leads through the coaxial unit for diagnostic or medicinal purposes. Visual means carried by the syringe indicate balloon failure.
