Hemostatic devices and methods of use

Abstract

An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a first component having a first substrate and a second component having a second substrate. The second component is positioned within the first component. One of the first and second substrates includes a hemostatic agent and the other of the first and second substrates includes an active pharmaceutical ingredient. Kits, systems and methods are disclosed.

         29 . The implantable medical device recited in  claim 28 , wherein the hemostatic agent is selected from the group consisting of epinephrine, tranexamic acid, chitosan and oxidized regenerated cellulose. 
     
     
         30 . The implantable medical device recited in  claim 21 , wherein the substrate is a sheet made from collagen and a second hemostatic agent, the hemostatic agents each consisting of tranexamic acid. 
     
     
         31 . The implantable medical device recited in  claim 21 , wherein the substrate is a collagen sheet, the implantable medical device comprising a polymer that coats at least a portion of the collagen sheet, the polymer including the hemostatic agent. 
     
     
         32 . The implantable medical device recited in  claim 31 , wherein the polymer comprises a tyrosine-derived polyarylate and the hemostatic agent. 
     
     
         33 . The implantable medical device recited in  claim 31 , wherein the polymer comprises a tyrosine-derived polyarylate, rifampin, minocycline and the hemostatic agent. 
     
     
         34 . The implantable medical device recited in  claim 31 , wherein the polymer is a tyrosine-derived polyarylate comprising a first layer including the hemostatic agent and a second layer including an active pharmaceutical ingredient. 
     
     
         35 . The implantable medical device recited in  claim 34 , wherein the active pharmaceutical ingredient comprises rifampin and minocycline. 
     
     
         36 . The implantable medical device recited in  claim 34 , wherein the second layer does not include the hemostatic agent. 
     
     
         37 . The implantable medical device recited in  claim 31 , wherein the polymer is a tyrosine-derived polyarylate comprising a first layer including a first amount of the hemostatic agent and a second layer including a second amount of the hemostatic agent, the second amount being different than the first amount. 
     
     
         38 . The implantable medical device recited in  claim 31 , wherein the polymer includes a first polymer defining a first layer and a second polymer defining a second layer, the first polymer including the hemostatic agent and the second polymer including an active pharmaceutical ingredient, the second polymer being different than the first polymer. 
     
     
         39 . An implantable medical device comprising:
 a sheet consisting of collagen; and   a coating that coats at least a portion of the sheet, the coating consisting of tranexamic acid.   
     
     
         40 . An implantable medical device comprising:
 a sheet consisting of collagen; and   a polymer that coats at least a portion of the sheet, the polymer consisting of a tyrosine-derived polyarylate, tranexamic acid, rifampin and minocycline.
