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.

1 . A method for making an inflatable device for use in a biological body comprising:
 forming a first film on a first portion of a mandrel;   forming a second film on a second portion of the mandrel;   joining the first film to the second film; and   eliminating the mandrel.   
     
     
         2 . The method of  claim 1 , further comprising adhering with a first bonding agent the first film to the mandrel. 
     
     
         3 . The method of  claim 1 , wherein joining comprises bonding with a second bonding agent the first film to a second film. 
     
     
         4 . The method of  claim 1 , wherein eliminating the mandrel comprises removing the mandrel. 
     
     
         5 . The method of  claim 1 , wherein eliminating the mandrel comprises dissolving the mandrel. 
     
     
         6 . The method of  claim 5 , wherein dissolving comprises applying water to the mandrel. 
     
     
         7 . The method of  claim 5 , wherein the first bonding agent is water soluble. 
     
     
         8 . The method of  claim 5 , wherein the mandrel comprises a sugar. 
     
     
         9 . The method of  claim 5 , wherein the mandrel comprises a plastic. 
     
     
         10 . The method of  claim 5 , wherein the mandrel comprises a polylactic acid. 
     
     
         11 . The method of  claim 5 , wherein the mandrel comprises a polyvinylacetate. 
     
     
         12 . The method of  claim 5 , wherein the mandrel comprises a water-soluble wax. 
     
     
         13 . A method for making an inflatable device for use in a biological body comprising:
 positioning a solid film on a mandrel; and   eliminating the mandrel.   
     
     
         14 . The method of  claim 13 , wherein eliminating the mandrel comprises removing the mandrel. 
     
     
         15 . The method of  claim 13 , wherein eliminating the mandrel comprises dissolving the mandrel. 
     
     
         16 . The method of  claim 15 , wherein dissolving comprises dissolving with water 
     
     
         17 . The method of  claim 25 , wherein the mandrel comprises a sugar. 
     
     
         18 . The method of  claim 25 , wherein the mandrel comprises a plastic. 
     
     
         19 . The method of  claim 25 , wherein the mandrel comprises a polylactic acid. 
     
     
         20 . The method of  claim 25 , wherein the mandrel comprises a polyvinylacetate. 
     
     
         21 . The method of  claim 25 , wherein the mandrel comprises a water-soluble wax. 
     
     
         22 . The method of  claim 25 , wherein the film is water-tight. 
     
     
         23 . The method of  claim 13 , wherein the film comprises a flat piece before forming on the mandrel. 
     
     
         24 . A method for making an inflatable device for use in a biological body comprising:
 positioning a film on a mandrel, wherein the mandrel comprises a plastic; and   eliminating the mandrel.   
     
     
         25 . The method of  claim 24 , wherein eliminating the mandrel comprises removing the mandrel. 
     
     
         26 . The method of  claim 24 , wherein eliminating the mandrel comprises dissolving the mandrel. 
     
     
         27 . The method of  claim 26 , wherein dissolving comprises dissolving with water. 
     
     
         28 . The method of  claim 26 , wherein the mandrel comprises a sugar. 
     
     
         29 . The method of  claim 26 , wherein the mandrel comprises polylactic acid. 
     
     
         30 . The method of  claim 26 , wherein the mandrel comprises polyvinylacetate. 
     
     
         31 . The method of  claim 26 , wherein the mandrel comprises a water-soluble wax.
