DEVICE FOR RF WELDING AN IV TUBE TO A CATHETER LUMEN ABSTRACT OF THE INVENTION A device for welding an IV tube into fluid communi- cation with a lumen of a catheter comprises a grounded metal adapter which is operatively associated with a dielectric collet to clampingly engage and hold a catheter in the collet. The device further comprises a metal mandrel which is par- tially inserted into an IV tube and positioned so that part of the IV tube and mandrel extend into a portion of a lumen of the catheter. With the IV tube and mandrel positioned in the lumen, the dielectric collet is further engaged to compres- singly urge the lumen sidewall into contact with the outer surface of the IV tube. RF energy is then applied to the mandrel to weld the IV tube into the lumen.
