ABSTRACT:
A balloon and method of manufacture for use in catheters for medical procedures, in particular percutaneous translumenal coronary angioplasty and other cardiovascular interventions. The balloon incorporates an inflatable membrane having a number of perpendicular ribs which have a higher resistance to collapse during deflation. A number of longitudinal ribs are provided which are preferably equidistantly spaced about a longitudinal axis and which extend between a proximal and distal end of the balloon. A number of triangular indentations are provided, wherein each triangular indentation is preferably equidistantly positioned between adjacent longitudinal ribs and each triangular indentation extends along a portion of the balloon between the proximal and distal ends. Each triangular indentation may extend through a perpendicular rib to reduce the resistance of the perpendicular rib to collapse during deflation. The number of triangular indentations enhance the collapse of the balloon from an expanded configuration to a folded configuration once the resistance of the number of perpendicular ribs to collapse has been overcome.
