Abstract
A catheter comprising, an elongated shaft, an inflatable balloon secured to the shaft, and an inflation lumen extending along the shaft and communicating with the balloon. The catheter has an inflation control assembly comprising a housing having a chamber, and a control member projecting into the chamber and having a circumferential sealing surface. The control assembly has a generally tubular valve element of flexible material having a sealing portion biased against the sealing surface. The valve element normally prevents passage of fluid through the housing, and flexes away from the sealing surface to permit inflation of the balloon. The valve element also flexes away from the sealing surface at a predetermined pressure in order to relieve pressure in the inflated balloon when overinflated.
