A corporeal access assembly including a tube segment having a body formed of silicone rubber and containing a coil spring embedded therein. The silicone rubber has a low durometer hardness of about 35 on the A scale. The tube segments have relatively large diameter liquid flow passages therethrough for all French sizes, from 12Fr to 24Fr. The body wall thickness for all French sizes remains the same. An air lumen is provided in one embodiment of the tube segment, with a set connector attached which has a removable plug for blocking or opening an air passage to a retention balloon.
