A stent delivery assembly includes a delivery balloon having a balloon surface with microbristles extending therefrom, wherein at least a portion of the microbristles has a length within a range of 0.8 through 1.2 mm. Another stent delivery assembly includes a delivery balloon having a balloon surface with microbristles extending therefrom and a stent disposed around the delivery balloon, wherein the stent has interconnected struts with a strut thickness and the delivery balloon has a balloon surface with microbristles extending therefrom, wherein at least a portion of the microbristles has a length that is greater than the strut thickness. The balloon surface may form a monolithic structure with the microbristles. The microbristles may be made of a stiffer material than the balloon surface.
