Title (EN) INTRACRANIAL CATHETER ASSEMBLY FOR PRECISE TREATMENT OF BRAIN TISSUE
(FR) ENSEMBLE CATHETER INTRACRANIEN POUR TRAITEMENT PRECIS DE TISSU CEREBRAL
Abstract: front page image
(EN)A catheter assembly (10) for intracranial treatment of a patient is disclosed. The assembly comprises an outer catheter (30) and an inner catheter (50). The outer catheter includes a proximal opening (31), at least one aperture (32), a lumen (33) connecting the opening and the aperture, and at least one element (40). The inner catheter (50) is adapted to be received within the lumen and includes a passageway (51) and at least one port (52) for transferring fluids between the inner catheter and a tissue region (81) within the patient's brain (80). The assembly facilitates regular accurate placement of the drug delivery catheter at the tissue region without additional extended contact with the brain during insertion.
(FR)L'invention concerne un ensemble cathéter (10) pour traitement intracrânien, qui comprend un cathéter externe (30) et un cathéter interne (50). Le cathéter externe comprend une ouverture proximale (31), au moins un orifice (32), une lumière (33) reliant l'ouverture et l'orifice, et au moins un élément (40). Le cathéter interne (50) peut être reçu dans la lumière, et il comprend un passage (51) et au moins un accès (52) pour le transfert de fluides entre le cathéter interne et une zone tissulaire (81) du cerveau (80). L'ensemble facilite le positionnement précis régulier du cathéter de délivrance de médicaments dans ladite zone, sans contact additionnel prolongé avec le cerveau en cours d'insertion.
