Abstract
A cannula is placed in an enlarged opening through a bladder wall and an abdominal wall by applying pulling tension to a placement guide extending through a small pathway to hold an inflated placement balloon in sealing contact with the bladder wall. The seal confines distension fluid in the bladder to establish sufficient reactive resistance to enlarge the opening through the bladder wall with blunt force dilation from an obturator.
