Abstract
The invention provides a catheter assembly having an elongate main body extending longitudinally between proximal and distal ends. A tip structure is attached to the distal end of the main body and also extends longitudinally. The main body and tip structure combine to define side-by-side intake and return lumens and the intake lumen terminates at a transverse intake opening at the distal end of the main body. The return lumen terminates at the distal end of the tip structure at a transverse return opening and a side opening is provided adjacent the return opening. A tubular applicator passes through the intake lumen, through the side opening and into the return lumen. This permits the assembly to be passed over a guide wire by engaging the wire inside the tubular applicator.
