A balloon catheter for deployment within a body vessel, the balloon catheter comprising: a shaft having a proximal portion extending to a distal portion and a lumen formed therethrough; and an inflatable balloon connected to the distal portion of the shaft and having a balloon wall comprising a balloon interior surface and a balloon exterior surface opposite the balloon interior surface, the balloon wall in fluid communication with the lumen for inflating the balloon to treat the body vessel defining an inflated state and for collapsing the balloon defining a deflated state, the balloon wall textured in the deflated state, the balloon in the inflated state being tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state; wherein said texture comprises a balloon interior surface roughness spatially registered with a balloon exterior surface roughness providing corresponding surface profiles, wherein the texture of the balloon wall reduces the force for collapsing the balloon to facilitate retrieval of the balloon catheter from the body vessel; and wherein the balloon is formed by blow molding with a internal mold surface textured to provide a surface profile with a mold surface roughness, said balloon exterior surface roughness conforming to said mold surface roughness, wherein either: the surface roughness value of the balloon exterior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 2 microns, and/or the surface roughness value of the balloon interior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 1.5 microns. a shaft having a proximal portion extending to a distal portion and a lumen formed therethrough; and an inflatable balloon connected to the distal portion of the shaft and having a balloon wall comprising a balloon interior surface and a balloon exterior surface opposite the balloon interior surface, the balloon wall in fluid communication with the lumen for inflating the balloon to treat the body vessel defining an inflated state and for collapsing the balloon defining a deflated state, the balloon wall textured in the deflated state, the balloon in the inflated state being tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state; wherein said texture comprises a balloon interior surface roughness spatially registered with a balloon exterior surface roughness providing corresponding surface profiles, wherein the texture of the balloon wall reduces the force for collapsing the balloon to facilitate retrieval of the balloon catheter from the body vessel; and wherein the balloon is formed by blow molding with a internal mold surface textured to provide a surface profile with a mold surface roughness, said balloon exterior surface roughness conforming to said mold surface roughness, wherein either: the surface roughness value of the balloon exterior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 2 microns, and/or the surface roughness value of the balloon interior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 1.5 microns. the surface roughness value of the balloon exterior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 2 microns, and/or the surface roughness value of the balloon interior surface in the deflated state is at least a numerical average surface roughness value (S a ) of 1.5 microns. <EOS>
