Inflatable medical devices

Abstract

Inflatable medical devices and methods for making and using the same are disclosed. The inflatable medical devices can be medical balloons. The balloons can be configured to have a through-lumen or no through-lumen and a wide variety of geometries. The device can have a high-strength, non-compliant, fiber-reinforced, multi-layered wall. The inflatable medical device can be used for angioplasty, kyphoplasty, percutaneous aortic valve replacement, or other procedures described herein.

We claim: 
     
         1 . A medical balloon for performing an angioplasty, comprising:
 a body including a wall having an inner layer, an outer layer, and an intermediate layer at least partially between the inner and outer layer, at least the intermediate layer comprising a radiopaque foil.   
     
     
         2 . The balloon of  claim 1 , further including an adhesive for laminating the foil to the inner or outer layer. 
     
     
         3 . The balloon of  claim 1 , wherein the foil is provided on a first portion of the balloon. 
     
     
         4 . The balloon of  claim 3 , wherein the first portion comprises a cylindrical portion of the balloon. 
     
     
         5 . The balloon of  claim 3 , wherein the first portion comprises a tapered portion of the balloon. 
     
     
         6 . The balloon of  claim 1 , wherein a fiber is provided between the inner layer and the outer layer. 
     
     
         7 . The balloon of  claim 1 , wherein the foil comprises a material selected from the group consisting of gold, platinum, platinum-iridium alloy, tantalum, palladium, bismuth, barium, tungsten, or combinations thereof. 
     
     
         8 . The balloon of  claim 1 , wherein the foil is less than about 30 μm thick 
     
     
         9 . The balloon of  claim 1 , wherein the foil is less than about 20 μm thick. 
     
     
         10 . The balloon of  claim 1 , wherein the foil is about 15 μm thick. 
     
     
         11 . The balloon of  claim 1 , wherein the foil is about 12 μm thick. 
     
     
         12 . The balloon of  claim 1 , wherein the foil is about 10 μm thick. 
     
     
         13 . The balloon of  claim 1 , wherein the foil is about 8 μm thick. 
     
     
         14 . The balloon of  claim 1 , wherein the body is non-compliant. 
     
     
         15 . A medical balloon for performing an angioplasty, comprising:
 a body including a wall having an inner layer, an outer layer, and a radiopaque foil therebetween.   
     
     
         16 . The balloon of  claim 15 , wherein the radiopaque foil comprises a single continuous layer. 
     
     
         17 . An apparatus comprising:
 a medical balloon; and   a radiopaque foil having a removable backing.
