Composite woven fabric for endoluminal devices

Abstract

A composite woven fabric for a low profile implantable medical device having a plurality of textile strands of a first material aligned in a first direction interlaced with a plurality of textile strands of a second material. The textile strands have a size between about 10 denier to about 20 denier. The first material has at least one characteristic different from the second material and the second material reacts more favorably with blood when placed within an artery.

         3 . The composite woven fabric of  claim 2 , where the second material comprises between about 50 and about 300 weft yarns per inch and between about 50 and about 300 warp yarns per inch. 
     
     
         4 . The composite woven fabric of  claim 1 , where the first material and the second material of comprise a polymer. 
     
     
         5 . The composite woven fabric of  claim 4 , where the first material comprises ultra-high molecular weight polyethylene and the second material comprises polyethylene terephthalate. 
     
     
         6 . The composite woven fabric of  claim 1 , where the woven fabric has a pick count between about 3 and about 500. 
     
     
         7 . The composite woven fabric of  claim 1 , where the fabric comprises a weave selected from the group consisting of a plain weave, a basket weave, a rep weave, a rib weave, a twill weave, a leno weave, a mock leno weave, a satin weave, a double weave, or a variation thereof. 
     
     
         8 . The composite woven fabric of  claim 7 , where the fabric comprises a plain weave. 
     
     
         9 . The composite woven fabric of  claim 1 , where the textile strands aligned in the first direction has at least one float of at least two textile strands aligned in the second direction. 
     
     
         10 . The composite woven fabric of  claim 1 , where the textile strands have a size of 20 denier. 
     
     
         11 . A composite woven fabric suitable for an implantable medical device comprising:
 polyethylene textile strands having a size between about 10 denier and about 20 denier aligned in a first direction interlaced with polyester textile strands having a size between about 10 denier to about 20 denier aligned in a second direction; and   a primary weave comprising a plain weave,   where the polyethylene textile strands aligned in the first direction comprise warp strands and the polyester textile strands aligned in the second direction comprise weft strands.   
     
     
         12 . The composite woven fabric of  claim 11 , where the polyester textile strands are polyethylene terephthalate. 
     
     
         13 . The composite woven fabric of  claim 11 , where the woven fabric has a pick count between about 3 and about 500. 
     
     
         14 . The composite woven fabric of  claim 11 , where the polyester textile strands and the polyethylene textile strands have a size of 20 denier. 
     
     
         15 . The composite woven fabric of  claim 11 , where the polyethylene textile strands aligned in the first direction have at least one float of at least two polyester textile strands aligned in the second direction. 
     
     
         16 . A method of producing a composite woven fabric for an implantable medical device comprising the steps of:
 providing a plurality of textile strands of a first material to be aligned in a first direction; and   providing a plurality of textile strands of a second material to be aligned in a second direction, the first material having at least one characteristic different from the second material; and   weaving the textile strands to produce a woven fabric;   where the textile strands have a size between about 10 denier to about 20 denier.   
     
     
         17 . The method of  claim 16 , where at least one of the textile strands in the first direction is woven to have at least one float of at least two textile strands in the second direction. 
     
     
         18 . The method of  claim 16 , where the textile strands aligned in the first direction comprise warp strands and the textile strands aligned in the second direction comprise weft strands. 
     
     
         19 . The method of  claim 16 , where the first material is polyethylene and the second material is polyethylene terephthalate. 
     
     
         20 . The method of  claim 16 , where the first material and the second material have a size of 20 denier.
