| 摘要 |
Optical fibre catheter particularly intended to conduct energy, such as light energy of a laser, into a blood vessel such as an arteria for removing its obstructions by percutaneous transluminal process. It will find its application particularly in the medical field for the treatment of diseases such as arteritis. According to the invention, the catheter (1) comprises a main tube (2) provided with a proximal end and a distal end (4), said tube presenting at least a first conduit (6) provided with a first outlet port (7) at the distal end (4), and an optical fibre (8) capable of conveying light energy from a laser, said optical fibre being arranged within the first conduit (6). The catheter is characterized in that said main tube (2) has a second conduit (10) provided with a second port (11) at the distal end (4), the axis of said first and second conduits (6) and (10) being substantially parallel to the axis of the main tube (2), said second conduit (10) being capable of conveying a mandrel facilitating the percutaneous insertion of the catheter (1) and/or of conveying a cooling and a washing solution.
