BIFURCATION POST-DILATATION BALLOON AND METHODS

摘要

A catheter assembly includes a balloon member and a balloon restricting arrangement. The balloon member includes a proximal portion, a distal portion and a circumferential bulge portion. The circumferential bulge portion extends around a circumference of the balloon member and is positioned at a location between the proximal and distal portions of the balloon member. The balloon restricting arrangement includes a proximal portion extending around the proximal portion of the balloon member and a distal portion extending around the distal portion of the balloon member to restrict an inflated size of the proximal and distal portions of the balloon member. The proximal and distal portions of the balloon restricting arrangement are spaced apart axially, and the circumferential bulge portion extends radially outward therebetween. The circumferential bulge portion inflates to a maximum inflated dimension that is greater than an inflated dimension of the proximal and distal portions of the balloon restricting arrangement.
