         7 . A downhole expandable liner hanger positioned in a subterranean wellbore, comprising:
 a liner; and   an expansion element, comprising:
 one or more spikes; and 
 one or more seal elements bonded to the expansion element in an open-ended containment system, wherein each of the one or more seal elements comprises at least one garter spring. 
   
     
     
         8 . The downhole expandable liner hanger of  claim 7 , wherein each of the one or more seal elements comprises a plurality of garter springs. 
     
     
         9 . The downhole expandable liner hanger of  claim 8 , wherein the plurality of garter springs are spaced apart by about 1 inch to about 10 inches. 
     
     
         10 . The downhole expandable liner hanger of  claim 7 , wherein the one or more seal elements engage a downhole tubular, and further wherein the one or more seal elements bear the axial load placed on the liner hanger. 
     
     
         11 . The downhole expandable liner hanger of  claim 7 , wherein the at least one garter spring has a square shape. 
     
     
         12 . The downhole expandable liner hanger of  claim 7 , wherein the at least one garter spring has a trapezoidal shape. 
     
     
         13 . The downhole expandable liner hanger of  claim 7 , wherein the at least one garter spring comprises stainless steel, stainless steel alloys, carbon steel, carbon steel allows, nickel alloys, or combinations thereof. 
     
     
         14 . A downhole expandable liner hanger positioned in a subterranean wellbore, comprising:
 an expansion element comprising:
 one or more spikes; and 
 one or more seal elements bonded to the expansion element in an open-ended containment system, wherein each of the one or more seal elements comprises at least one garter spring. 
   
     
     
         15 . The downhole expandable liner hanger of  claim 13 , wherein each of the one or more seal elements comprises a plurality of garter springs.
