Double lumen catheter.

摘要

Method for manufacturing a double-lumen catheter, comprising of receiving into a mould with a Y-shaped mould cavity the end part of a two-channel catheter basic material (1) with core wires (11,12) inserted therein, each wire having a first portion (13) closely fitting in the channels (3,4) and a second portion (14) with a cross section substantially corresponding with the external cross section of the single-channel basic material and a transitional portion therebetween, the shape of the section of which gradually transposes from that of the first portion (13) to that of the lengthwise channel of the single-channel basic material, filling the mould cavity (18) with a curable material, removing the formed assembly from the mould cavity (18) after the curable material has hardened to a fork piece (22), removing the core wires (11,12) from the fork piece (22), fixing the pieces of single-channel basic material (23,24) in the cavities in the fork piece (22) defined by the second portions (14) of the core wires (11,12), fixing to the other ends of the pieces of single-channel basic material connecting members (25,26) which can allow passage respectively of a guide wire (32) and an optic fibre bundle (31).
