SAFETY CATHETER AND METHOD ABSTRACT OF THE DISCLOSURE A catheter for insertion through a body canal to a body cavity and retention therein. The catheter has an elongated shaft having a proximal end, a distal end, and an inflation lumen. The catheter also has an elongated flexible balloon overlying the shaft and having a length approximating or greater than the length of the body canal, with the bal- loon and shaft defining a space communicating with the infla- tion lumen for inflation of the balloon. The balloon has a distal end portion for placement and inflation in the body cavity, and a proximal end portion being sufficiently elastic to maintain the distal end portion inflated when the distal end portion is located in the body cavity. The proximal end portion is also sufficiently elastic to inflate outside the body canal when the distal end portion is obstructed by the body canal.
