<p>A multilumen catheter comprises separate proximal IV tubes of substantially circular cross-section welded in fluid communication with each of the substantially elliptical-shaped lumens of the catheter. The weld, at the interface between the outer surface of each IV tube and the associated lumen sidewall, is continuous over the interface to provide for an integral fluid sealing connection between the catheter lumen and the IV tube.</p> |
