each of the three co planar radially projecting legs 31 a 31 b and 31 c may be symmetrical or asymmetrical relative to one another however in order to achieve uniform geometric deformation across the entire graft body member 12 it is preferable that each of the plurality of microperforations 20 has geometric symmetry those skilled in the art will recognize that beyond the two particular patterns described here any number of different patterns may be used without significantly departing from the inventive graft concept described in the present patent those skilled in the art will understand that each of the microperforations 20 are capable of undergoing deformation upon application of a sufficient force in a tubular geometry the graft 12 may deform both circumferentially and longitudinally as is illustrated in fig3 b each of the plurality of elongated slots may deform into opened microperforations which assume a generally rhomboidal shape similarly y shaped microperforations 20 shown in fig4 are capable of deformation into generally circular or oval open microperforations 21 the deformation regions 22 between adjacent microperforations 20 facilitate deformation of each of the plurality of microperforations 20 by deforming to accommodate opening of each of the plurality of microperforations 20 as depicted in fig5 the inventive graft 12 may be folded to assume a smaller diametric profile for endoluminal delivery in order to facilitate folding the pattern of the plurality of microperforations 20 may be fashioned to create a plurality of folding regions 23 that constitute relatively weakened regions of the graft 12 to permit folding the graft 12 along folding regions 23.
