Abstract

Various embodiments provide a device comprising a balloon disposed at least partially along a template, the template including an aperture, wherein the template has a substantially cylindrical portion that resists deformation in a radial direction, wherein the balloon expands radially during inflation, wherein a portion of the balloon at least partially protrudes about the aperture. Other embodiments are directed toward balloons having textured surfaces.
