Abstract

Medical devices as wells as methods for making and using medical devices are disclosed. An example medical device may include a left atrial appendage device. The left atrial appendage device may include an expandable frame configured to shift between a first configuration and an expanded configuration. A fabric mesh may be disposed along at least a portion of the expandable frame. An anti-thrombogenic coating may be disposed along the fabric mesh.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An occlusive medical device, comprising:
 an expandable frame configured to shift between a first configuration and an expanded configuration;   a fabric disposed along at least a portion of the expandable frame;   wherein the fabric includes a plurality of filaments; and   an anti-thrombogenic coating incorporated within the fabric.   
     
     
         2 . The occlusive medical device of  claim 1 , wherein the plurality of filaments are arranged into a fiber bundle. 
     
     
         3 . The occlusive medical device of  claim 2 , wherein the anti-thrombogenic coating is disposed along an interior region of the fiber bundle. 
     
     
         4 . The occlusive medical device of  claim 1 , wherein the plurality of filaments include polyethylene terephthalate. 
     
     
         5 . The occlusive medical device of  claim 1 , wherein the plurality of filaments include polyester. 
     
     
         6 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating encapsulates at least some of the plurality of filaments. 
     
     
         7 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating individually coats each of the plurality of filaments. 
     
     
         8 . The occlusive medical device of  claim 1 , wherein the plurality of filaments are arranged in a non-woven configuration. 
     
     
         9 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating includes a fluoropolymer. 
     
     
         10 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating includes polyvinylidene fluoride. 
     
     
         11 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating includes a polyvinylidene fluoride copolymer. 
     
     
         12 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating includes poly(vinylidene fluoride-co-hexafluoropropylene). 
     
     
         13 . The occlusive medical device of  claim 1 , wherein the anti-thrombogenic coating includes poly[bis (trifluoroethoxy)phosphazene]. 
     
     
         14 . A left atrial appendage device, comprising:
 an expandable frame configured to shift between a first configuration and an expanded configuration;   a fabric disposed along at least a portion of the expandable frame, the fabric including a fiber bundle; and   an anti-thrombogenic coating disposed within the fiber bundle.   
     
     
         15 . The left atrial appendage device of  claim 14 , wherein the anti-thrombogenic coating is disposed along an interior region of the fiber bundle. 
     
     
         16 . The left atrial appendage device of  claim 14 , wherein the fabric includes polyethylene terephthalate. 
     
     
         17 . The left atrial appendage device of  claim 14 , wherein the anti-thrombogenic coating includes poly(vinylidene fluoride-co-hexafluoropropylene). 
     
     
         18 . The left atrial appendage device of  claim 14 , wherein the anti-thrombogenic coating includes poly[bis (trifluoroethoxy)phosphazene]. 
     
     
         19 . A left atrial appendage device, comprising:
 an expandable frame configured to shift between a first configuration and an expanded configuration;   an occlusive member disposed along at least a portion of the expandable frame, the occlusive member including a fiber bundle that includes one or more filaments; and   an anti-thrombogenic coating disposed on the occlusive member, the anti-thrombogenic coating encapsulating at least some of the one or more filaments.   
     
     
         20 . The left atrial appendage device of  claim 19 , wherein the anti-thrombogenic coating encapsulates all of the one or more filaments.
