Title
(EN) BIO-RESORBABLE MICROSTRUCTURED OPTICAL FIBER TO RELEASE FLUIDS, IN PARTICULAR DRUGS, AND TO TRANSMIT LIGHT
(FR) FIBRE OPTIQUE MICROSTRUCTURÉE BIORÉSORBABLE POUR LIBÉRER DES FLUIDES, EN PARTICULIER DES MÉDICAMENTS, ET POUR TRANSMETTRE DE LA LUMIÈRE
Abstract
(EN)
A microstructured bioresorbable optical glass fiber comprises a compound including phosphorus oxide, magnesium oxide and calcium oxide; so as to provide a loss of no more than 22 dB/m for a radiation having a wavelength of 633 nm when curved with a curvature of 10 cm; and has a longitudinal channel (2) having a diameter such to release and/ or uptake a liquid.
(FR)
Fibre de verre optique biorésorbable microstructurée comprenant un composé contenant de l'oxyde de phosphore, de l'oxyde de magnésium et de l'oxyde de calcium ; de manière à assurer une perte maximale de 22 dB/m pour un rayonnement ayant une longueur d'onde de 633 nm lorsqu'elle est incurvée avec une courbure de 10 cm ; et a un canal longitudinal (2) ayant un diamètre tel qu'il permet la libération et/ou l'absorption d'un liquide.
