Abstract
An improved balloon catheter is disclosed that facilitates catheter release when a pull is entered upon the inserted catheter while the balloon is inflated in a body passageway. The catheter is provided with one or more weakened regions on the inflatable balloon portion. These weakened regions may be provided by portions of non-uniform thicknesses arranged circumferentially around the balloon. These weakened regions rupture and release the inflation when the catheter is pulled from its inserted, inflated position. This mechanism allows for a tight seal on the body passageway while alleviating the danger of accidental removal with the balloon in its inflated state.
