Abstract: Balloon catheters, sleeves, cages, cylindrical structures and endoluminal prostheses are provided with stress-applying and spacing features coupled to expandable surfaces thereof. At least one or at least some stress-applying features are immobilized onto the surface or into pre-formed indentations formed in the expandable surface. The stress-applying and spacing features may have blunt and/or rounded contact regions which contact tissue or calcified regions in the vasculature. The contact regions dent or fracture occlusive material on the wall of a vascular lumen and/or patient valve leaflets when expanded. The spacing of features can permit blood, drug, and contrast perfusion past structures expanded in the vasculature, particularly balloon catheters.
