Zusammenfassung:	A catheter (10) for the administration of a liquid agent at a target site includes a catheter tube (11), a handle (12) and a conduit (13) that extends through a central volume formed in the handle. The catheter includes a guidewire lumen (22) and two parallel liquid agent transfer lumens (23 24). The conduit seals into the proximal end of the guidewire lumen and to the handle at a first entry port (30) and spans the central volume. The tube therefore prevents the transfer of any liquid agent into the guidewire lumen and provides a passageway for enabling the catheter to transfer over the guidewire. With two transfer lumens the catheter tube provides a maximum transfer flow rate while maintaining the ability of the catheter to resist kinking and bending.
