Catheter for administering a liquid agent |
摘要 |
A catheter for the administration of a liquid agent at a target site includes a catheter tube, a handle and a conduit that extends through a central volume formed in the handle. The catheter includes a guidewire lumen and two parallel liquid agent transfer lumens. The conduit seals into the proximal end of the guidewire lumen and to the handle at a first entry port 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.
