Non-compliant medical balloon having a longitudinal fiber layer

Abstract

A non-compliant medical balloon is formed with a first fiber layer including a first fiber and a second fiber layer over said first fiber layer. The first fiber is substantially parallel to a longitudinal axis of the non-compliant medical balloon.

         23 . The method of  claim 22 , wherein the applying step comprises attaching the at least one fiber in direction substantially parallel to the longitudinal axis of the balloon. 
     
     
         24 . The method of  claim 22 , wherein the applying step comprises attaching the at least one fiber in direction substantially perpendicular to the longitudinal axis of the balloon. 
     
     
         25 . The method of  claim 22 , wherein the applying step comprises:
 attaching a plurality of fibers in direction substantially parallel to the longitudinal axis of the balloon; and   attaching the at least one fiber in direction substantially perpendicular to the longitudinal axis of the balloon.   
     
     
         26 . The method of  claim 21 , further including the step of providing a base layer on the mandrel prior to the forming step. 
     
     
         27 . The method of  claim 26 , further including the step of curing the base layer. 
     
     
         28 . The method of  claim 21 , wherein the removing step comprises dissolving the mandrel. 
     
     
         29 . The method of  claim 21 , wherein the removing step comprises changing the temperature of the mandrel. 
     
     
         30 . The method of  claim 21 , wherein the removing step comprises melting the mandrel. 
     
     
         31 . The method of  claim 21 , wherein the removing step comprises applying a solvent to the mandrel. 
     
     
         32 . A method for making a medical balloon having a longitudinal axis, comprising:
 providing a removable mandrel including a cylindrical barrel section and two conical end sections;   applying at least one fiber layer to the mandrel; and   removing the mandrel.   
     
     
         33 . The method of  claim 32 , wherein the applying step comprises applying a fabric to the mandrel. 
     
     
         34 . The method of  claim 33 , further including the step of applying a fiber over the fabric. 
     
     
         35 . The method of  claim 32 , wherein the applying step comprises;
 providing the at least one fiber layer in the form of a plurality of fibers extending in direction substantially parallel to the longitudinal axis of the balloon; and   providing at least one fiber in direction substantially perpendicular to the longitudinal axis of the balloon.   
     
     
         36 . The method of  claim 32 , further including the step of applying an adhesive to the mandrel prior to the applying step. 
     
     
         37 . A method for forming a non-compliant medical balloon having a longitudinal axis, comprising:
 providing a mandrel;   applying a first fiber layer to the mandrel;   applying a second fiber layer over the first fiber layer;   coating the first or second fiber layer with a coating; and   removing the mandrel.   
     
     
         38 . The method of  claim 37 , wherein the applying step comprises applying a first fabric to the mandrel including fibers extending substantially parallel to the longitudinal direction. 
     
     
         39 . The method of  claim 37 , wherein the applying step comprises applying the second fiber layer in the form of at least one fiber extending substantially perpendicular to the longitudinal direction. 
     
     
         40 . The method of  claim 37 , further including the step of curing the coating prior to removing the mandrel.
