Abstract
A balloon catheter includes a flexible tubular body having a distensible portion inflatable by a balloon. The tubular body is formed with a longitudinally-extending split at the distensible portion, and the balloon is disposed around the distensible portion with the opposite ends of the balloon secured to the two longitudinal edges of the tubular body along the split. The arrangement is such that inflating the balloon dilates the tubular body at the distensible portion, and also applies a tension force to the longitudinal edges of the tubular body at the split, opening the tubular body at the split to produce a flowpath of large cross-sectional area for the fluid through the distensible portion.
