Abstract

See full text

A tubular catheter having an inflatable expander member mounted thereon at the distal end thereof is provided with an extremely fine slit passing through the wall of the tubular catheter such that when a liquid is introduced under pressure into the proximal end thereof for inflating the balloon, any air present in the lumen of the catheter and in the yet unexpanded balloon is forced out through the slit. The slit or vent opening through the tube wall is so small that when the catheter is again aspirated to remove the purging fluid, air does not re-enter the expander through the vent opening.
