         2 . The vacuum deposition substrate of  claim 1  wherein the at least one of the plurality of patterned recesses or the at least one of a plurality of patterned raises is configured to define a geometry of a scaffold. 
     
     
         3 . The vacuum deposition substrate of  claim 1  wherein the vacuum deposition substrate is tubular. 
     
     
         4 . The vacuum deposition substrate of  claim 1  wherein the at least one of the plurality of patterned recesses or the at least one of a plurality of patterned raises is configured to define a geometry of a stent. 
     
     
         5 . The vacuum deposition substrate of  claim 1  wherein vacuum deposition substrate is substantially planar. 
     
     
         6 . The vacuum deposition substrate of  claim 1  wherein the vacuum deposition substrate is arcuate. 
     
     
         7 . The vacuum deposition substrate of  claim 1  further comprised of a deoxygenated copper material. 
     
     
         8 . The vacuum deposition substrate of  claim 7  further comprised of a titanium nitride coating on a surface. 
     
     
         9 . The vacuum deposition substrate of  claim 8  wherein the titanium nitride coating is configured as a diffusion barrier to prevent migration of copper into a deposited layer. 
     
     
         10 . The vacuum deposition substrate of  claim 1  further configured to be rotated about a longitudinal axis, moved in an X-Y plane, or planatarily or rotationally moved within a deposition chamber to facilitate deposition or patterning of a deposited material onto the vacuum deposition substrate. 
     
     
         11 . The vacuum deposition substrate of  claim 2  wherein the patterned openings comprise a plurality of circular openings passing through the vacuum deposition substrate. 
     
     
         12 . The vacuum deposition substrate of  claim 11  wherein the plurality of circular openings is patterned in a regular array of rows and columns with regular inter-opening spacing 165 between adjacent openings. 
     
     
         13 . The vacuum deposition substrate of  claim 12  wherein a diameter of each of the plurality of circular openings is about 19 μm, with an inter-opening spacing in each row and column of about 34 μm on center. 
     
     
         14 . The vacuum deposition substrate of  claim 2  wherein the patterned openings comprise an alternating slot pattern in which the patterned openings are arrayed adjacent one another forming a y-axis oriented array relative to the vacuum deposition substrate, further wherein a second plurality of patterned openings are arrayed adjacent one another forming an x-axis oriented array relative to vacuum deposition substrate. 
     
     
         15 . The vacuum deposition substrate of  claim 14  inter-array wherein the alternating slot pattern includes a spacing between the y-axis oriented array and the x-axis oriented array of about 17 μm, further wherein each of the plurality of openings has a length of about 153 μm and a width of about 17 μm. 
     
     
         16 . The vacuum deposition substrate of  claim 2  wherein the patterned openings comprise an array of a plurality of diamond-shaped openings passing through the vacuum deposition substrate. 
     
     
         17 . The vacuum deposition substrate of  claim 16  wherein the plurality of diamond-shaped openings includes a dimension configured to permit cellular migration through the plurality of diamond-shaped openings while preventing blood flow or seepage, and passage of embolic material through the plurality of diamond-shaped openings.
