Medical balloon

Abstract

A non-compliant medical balloon, where the non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon, is made with a first fiber layer, a second fiber layer over said first fiber layer such that the fibers of the first fiber layer and the fibers of the second fiber layer form an angle and a binding layer coating the first fiber layer and said second fiber layer. The interior surface area of the non-compliant medical balloon remains unchanged when the balloon changes from a deflated state to an inflated state

What is claimed is:  
     
         1 . A non-compliant medical balloon, where the non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon, comprising: 
 a first fiber layer;    a second fiber layer over said first fiber layer such that the fibers of the first fiber layer and the fibers of the second fiber layer form an angle;    a binding layer coating the first fiber layer and said second fiber layer;    wherein an interior surface area of the non-compliant medical balloon remains substantially unchanged when the balloon changes from a deflated state to an inflated state.    
     
     
         2 . The non-compliant medical balloon of  claim 1 , wherein said first fiber layer comprises inelastic fibers.  
     
     
         3 . The non-compliant medical balloon of  claim 1 , wherein said first fiber layer comprises a plurality of parallel first fibers.  
     
     
         4 . The non-compliant medical balloon of  claim 1 , further comprising an adhesive layer adhering to said first fiber layer.  
     
     
         5 . The non-compliant medical balloon of  claim 1 , wherein said second fiber layer comprises a plurality of parallel second fibers.  
     
     
         6 . The non-compliant medical balloon of  claim 1 , wherein said angle is substantially a right angle.  
     
     
         7 . The non-compliant medical balloon of  claim 1 , wherein said angle does not change when the balloon changes from a deflated state to an inflated state.  
     
     
         8 . The non-compliant medical balloon of  claim 3 , wherein said plurality of parallel first fibers are substantially parallel to the longitudinal axis of the balloon.  
     
     
         9 . The non-compliant medical balloon of  claim 5 , wherein said plurality of parallel second fibers are substantially transverse to the longitudinal axis of the balloon.  
     
     
         10 . The non-compliant medical balloon of  claim 1 , wherein said binding layer is a polymeric coating.  
     
     
         11 . The non-compliant medical balloon of  claim 10 , wherein said polymeric coating is formed of a polymer.  
     
     
         12 . The non-compliant medical balloon of  claim 10 , wherein said polymeric coating is formed of a copolymer.  
     
     
         13 . The non-compliant medical balloon of  claim 3 , wherein said parallel first fibers each have a thickness of about 0.0005 inch.  
     
     
         14 . The non-compliant medical balloon of  claim 5 , wherein said parallel second fibers each have a thickness of about 0.0005 inch.  
     
     
         15 . The non-compliant medical balloon of  claim 5 , wherein said parallel second fibers have a wind density of approximately 50 wraps per inch.  
     
     
         16 . The non-compliant medical balloon of  claim 1 , wherein said angle is about ten degrees.  
     
     
         17 . The non-compliant medical balloon of  claim 1 , further comprising a third fiber layer on said second fiber layer.
