Title
(EN) BIOABSORBABLE BRACHYTHERAPY DEVICE
(FR) DISPOSITIF DE CURIETHERAPIE BIOABSORBABLE
Abstract
(EN) A bioabsorbable brachytherapy device (110) includes a tubular housing (112) with sealed ends (122, 124) enclosed radioactive material (126). The radioactive material includes a radioisotope, such as palladium-103 or iodine-125. The tubular housing is made from a biocompatible and bioabsorbable polymeric material, and is sealed by means such as heat welding or solvent fixing. The device may further include a radiopaque medium and one or more therapeutic drugs.
(FR) La présente invention concerne un dispositif de curiethérapie bioabsorbable, comprenant un boîtier tubulaire qui présente des extrémités scellées et renferme un matériau radioactif. Ce matériau radioactif comprend un radio-isotope, tel que le palladium 103 ou l'iode 125. Le boîtier tubulaire est constitué d'un matériau polymère biocompatible et bioabsorbable et est scellé par des moyens tels que le thermosoudage ou la fixation par solvant. Ledit dispositif peut également comprendre un produit de contraste et un ou plusieurs médicaments thérapeutiques.
