DEVICE AND PROCEDURE FOR THE INTERSTICIAL APPLICATION OF LASER ENERGY.

摘要

A CATHETER AND A MOBILE NEEDLE SYSTEM (15''15 '' '') DESCRIBING ONE OR MORE ELEMENTS OF FIBER OPTIC (23''23 '' '') AND THERMOMEDITION DEVICES (24) ARE DESCRIBED THROUGH A WALL OF PASSAGE OF THE BODY AND IN THE MASS OF AN ADJACENT ORGAN (43). THE CATHETER IS PLACED NEXT TO THE ORGAN AND THE NEEDLES ARE EXTENDED TO MECHANICALLY PUNCH THE WALL AND ENTER THE ORGAN WITH THE FIBER OPTIC ELEMENTS. THE NEEDLE MAY BE SEPARATED FROM THE CATHETER BEFORE DEVELOPING LASER ENERGY REMAIN IN THE ORGAN TO SERVE AS A SUCTION-IRRIGATION VEHICLE. LUMENS (16) PROVIDED IN THE CATHETER TO TRANSPORT THE CONCAVE NEEDLES MAY WANT TO BE USED FOR ASPIRATION OR IRRIGATION OF THE PASSAGE. A DILATION BALLOON (19,20) MAY BE PROVIDED IN ORDER TO FIX AND TEMPORARILY SUPPORT THE CATHETER WHILE THE NEEDLE IS INSERTED IN THE ORGAN. THE TEMPERATURE OF THE TREATED AREA IS MONITORED THROUGH THERMO-MEASURING DEVICES PROVIDED IN THE FIBER OPTIC ELEMENTS. SMALL PUNCTURE HOLES CREATED BY CONCAVE NEEDLES QUICKLY AND REDUCE THE RISK OF INFECTION.
