Flexible and plastic radiopaque laminate composition

Abstract

A flexible laminate composition and methods for manufacturing same are provided. The flexible laminate composition includes one or more discrete and separate layers of a radiopaque material wherein the radiopaque layer is applied via a solvent to a layer that is composed of a plastic material. The laminate composition can be formed into a radiopaque marker band that can be used with a medical device, such as a catheter, for radiographic imaging. The laminate composition as an alternative can also be utilized to form the catheter or other suitable medical device.

       2 . The flexible laminate composition of  claim 1 , wherein the composition is formed into a medical device.  
   
   
       3 . The flexible laminate composition of  claim 2 , wherein the medical device is a catheter.  
   
   
       4 . The flexible laminate composition of  claim 1 , wherein the composition is formed into a radiopaque marker band.  
   
   
       5 . The flexible laminate composition of  claim 4 , wherein the radiopaque marker band can be RF or heat bonded to a medical device.  
   
   
       6 . The flexible laminate composition of  claim 1 , wherein the radiopaque material is selected from the group consisting of bismuth oxychloride, bismuth subcarbonate, bismuth trioxide, barium sulfate, tungsten, tantlium, platinum, silver, gold, copper, carbon and combinations thereof.  
   
   
       7 . The flexible laminate composition of  claim 6 , wherein the radiopaque material has a particle size ranging from about 2 microns to about 120 mesh screen size.  
   
   
       8 . The flexible laminate composition of  claim 6 , wherein the radiopaque material is a perforated metal foil.  
   
   
       9 . The flexible laminate composition of  claim 1 , wherein the plastic material includes a solution grade plastic coating resin.  
   
   
       10 . The flexible laminate composition of  claim 9 , wherein the plastic material is selected from the group consisting of polyurethane, polyester, polyether, polycaprolactone, and mixtures thereof.  
   
   
       11 . The flexible laminate composition of  claim 9 , wherein the plastic material is selected from the group consisting of a copolymer of vinyl chloride and vinyl acetate, polyvinyl chloride and mixtures thereof.  
   
   
       12 . The flexible laminate composition of  claim 9 , wherein the plastic material is composed of a silicone elastomer.  
   
   
       13 . A method of manufacturing a flexible laminate composition, the method comprising: 
 applying a radiopaque material via a solvent to a plastic layer composed of a plastic material; and    forming a uniform layer of the radiopaque material on the plastic layer.    
   
   
       14 . The method of  claim 13 , wherein the solvent is selected from the group consisting of methyl ethyl ketone, tetrahydrofuran, dimethylformamide, toluene, acetone, heptane, cyclohexane, and combinations thereof.
