<p>A solid introducer needle with a light guide unit (211) for catheter assemblies is provided, which comprises a sharp rigid needle-like member (202) and a light guide (210), forming a substantially monolithic structure. The monolithic structure is thus non-transparent for optical radiation over its entire length, allowing optical radiation to be emitted solely at the distal end thereof. Unit (211) is preferably provided with an adapter (209), via which adapter unit (211) may be connected to an electronic module (301), thus forming a catheter assembly (201). The light guide (210) is configured to receive by its proximal end at least one light beam from at least one light source of the electronic module device, to further conduct said optical radiation beam throughout internal space thereof and to emit optical radiation beam at a distal end thereof. Optical radiation, thus emitted at the distal end of the unit (211), is preferably of such a wavelength, to be strongly absorbed by blood and walls of the blood vessels.</p> |
