Tunneling catheter system for ablating vascular chronic total occlusion

摘要

The present invention relates to a tunneling catheter system for the complete removal of chronic stricture disease , longitudinally at the distal end a hollow catheter (110) and having a through- hole formed by ; The through hole provided cutting tip 111 is projected forward as the catheter 110 is a tool for removing the lesion before and after the movement is possible in the (120) and ; Including drive means ( 150 ) for the fluid 141 as a medium to generate a reciprocating motion of the tool 120 for removing lesions , chronic stenosis lesion completely removed with a high degree of proficiency of the operator as compared to using a conventional guidewire efficiently without requiring even has an effect capable of removing water in the vascular stenosis . ;
