摘要

AN APPLICATION SYSTEM (10) IS DISCOVERED FOR THE APPLICATION AND DEPLOYMENT OF DEVICES (23) THAT HAVE ABRASIVE PORTIONS (24) WITHIN THE PATIENT'S LUMEN. A LUMEN IN A FLEXIBLE CATETER (13) THAT IS PROXIMALLY EXTENDED FROM A DISTAL END (15) OF THE CATETER RECEIVES THE DEVICE IN A COMPACT FORM. AT LEAST ONE IMPENETRABLE SEGMENT (20) PLACED IN THE LUMEN COVER THE ABRASIVE PORTIONS OF THE DEVICE TO PROTECT AND DAMAGE THE CATHETER FROM THE ABRASIVE PORTIONS. THE SEGMENT IS OF RELATIVELY SHORT LENGTH IN A MODE THAT THE CATHETER REMAINS RELATIVELY FLEXIBLE THROUGH TO FACILITATE THE TRANSIT OF THE CATHETER THROUGH THE PATIENT'S LUMEN TO AN APPLICATION PLACE. ADDITIONAL SEGMENTS (50, 51, 52) MAY BE AVAILABLE IN THE CATETER DIFFERENTLY TO THE SEGMENT OR THE SEGMENT CAN BE MOVED WITH THE DEVICE TO THE DISTAL EXTREME TO DAMAGE THE CATHETER DURING THE DEPLOYMENT OF THE DEVICE. ADDITIONAL SEGMENTS CAN BE FITTED WITH THE SEGMENT OF THE MODE THAT THE FOLLOWED FOLLOWS PRESENT A RELATIVE RADIAL DEFLECTION.
