Implantable electrical cable and method of making

Abstract

The present invention is an implantable cable and a process to manufacture said implantable cable. The cable is composed of a biocompatible fluoropolymer, in which biocompatible conductor wires are embedded. The entire cable is heat treated at various stages to ensure the wires are securely embedded. The cable is then undulated to enhance its pliability and flexibility. Further treatment activates the outer surface of the cable, following which it may be encapsulated in silicone.

1 . An implantable cable comprising: 
 a plurality of conductor wires embedded within a fluoropolymer film;    said fluoropolymer film comprising outer surfaces and at least one tip;    said fluoropolymer film being overall undulated;    said fluoropolymer film being removed at a tip of said implantable cable;    
   
   
       2 . The implantable cable of  claim 1 , wherein said fluoropolymer is activated.  
   
   
       3 . The implantable cable of  claim 1 , wherein said fluoropolymer is activated by sodium treatment of said implantable cable.  
   
   
       4 . The implantable cable of  claim 1 , wherein said fluoropolymer is activated by plasma treatment of said implantable cable.  
   
   
       5 . The implantable cable of  claim 2 ,  3  or  4 , wherein said cable is encased with silicone after activating said fluoropolymer.  
   
   
       6 . The implantable cable of  claim 1 , wherein said biocompatible film is comprised of FEP or PFA.  
   
   
       7 . The implantable cable of  claim 1 , wherein said conductor wires are comprised of Pt or Pt/Ir.  
   
   
       8 . The implantable cable of  claim 7 , wherein said conductor wires have round, oval or rectangular cross sections.
