Claim:
1. An implantable medical graft, comprising: a. A generally seamless continuous tubular body member comprising a film selected from the group consisting of metallic and pseudometallic materials and having a luminal wall surface, an abluminal wall surface, and a wall thickness intermediate the luminal wall surface and the abluminal wall surface; and b. At least a portion of the body member having a plurality of circumferential corrugations defined by a radially undulating pattern of longitudinally alternating radially extending peaks and valleys in the abluminal wall surface of the body member and a radially undulating longitudinally alternating pattern of radially extending peaks and valleys in the luminal wall surface of the body member, wherein each peak in the luminal surface is longitudinally coincident with each peak in the abluminal surface and each valley in the luminal surface is longitudinally coincident with each valley in the abluminal surface, wherein a plurality of microperforations is disposed through the wall thicknesses composing the coincident peaks and the wall thicknesses composing the coincident valleys and wherein the plurality of microperforations provide fluid migration between the luminal and abluminal wall surfaces.
