12 to the body at different points in time alternatively or additionally the degradable plugs may degrade at different rates to expose the same bioactive agent in different internal cavities 12 at different periods of time to effectively elongate the period of time during which the bioactive agent is delivered the body element 10 is preferably formed of a metal such as titanium vanadium aluminum nickel tantalum zirconium chromium silver gold silicon magnesium niobium scandium platinum cobalt palladium manganese molybdenum and alloys thereof such as zirconium titanium tantalum alloys nitinol or stainless steel turning to fig5 7 there is illustrated an alternative embodiment of the inventive endoluminal stent 30 fabricated from a plurality of tubular structural elements 31 formed into a tubular stent and having a desired geometry it will be appreciated that the generally hexagonal cell geometric pattern defining a plurality of interstices 32 as illustrated in fig5 is merely exemplary and a myriad of different geometries of different geometric complexities are contemplated by the invention each of the tubular structural elements 31 has a central lumen that forms the internal cavity 37 within each structural element 31 a plurality of separation members 38 may be provided to subdivide the internal cavity 37 into a plurality of discontinuous internal cavities 37 each of the tubular structural elements 31 has a plurality of openings 36 which communicate between the internal cavity 37 and one or both of a luminal surface 33 or an abluminal surface 35 of each of the plurality of tubular structural elements 31 the tubular structural elements 31 may assume any.
