ABSTRACT:
A multi-luminal catheter is characterized in that the cross-sectional shape of each lumen at a connection portion for an extension tube is molded in accordance with the outer shape of the extension tube to be connected. Accordingly, smooth and hermetic connection between a catheter body and the extension tube, that has not been accomplished in the past, can be obtained, and the formation of steps of the lumen which increases fluid resistance can be prevented. This mult-luminal catheter can be produced by pressing a core metal having substantially the same shape as that of the outer shape of the extension tube into each lumen of the catheter body at the connection portion for the extension tube and inserting the connection portion for the extension tube into a molding die while heating it. Higher airtightness and connection strength can be obtained by fitting the connection end of the extension tube into each lumen at the connection portion of the multi-luminal catheter and integrating them by use of a fixing member.
