<p>PURPOSE:To prevent the connection between an air feeding port and a liquid feeding port as well as between these and the outside by providing the branch portion between the air feeding port and liquid feeding port in a position separated from the end to hand of a flexible pipe and fixing this branch portion. CONSTITUTION:In a balloon catheter 1 by means of a flexible pipe, only an air feeding port 4 is singly connected to a branch pipe 8 with a liquid feeding port 5 being completely separated from the air feeding port 4, and the periphery of the branch pipe 8 being connected to the air feeding port 4 is fixed by means of an adhesive 9. Therefore, no gap for connecting the air feeding port to the liquid feeding port is generated, without totally causing the connection between the air feeding port and liquid feeding port even if bubbles are generated inside.</p> |
