Title (EN) CATHETER WITH SIDE PORTS AND METHODS OF USE
(FR) CATHÉTER AVEC ORIFICES LATÉRAUX ET PROCÉDÉS D'UTILISATION
Abstract:
(EN) A catheter with a lumen and comprising side port(s) through the elongate body of the catheter at predetermined locations. The side port(s) may be positioned at anatomical locations of interest and a fluid, e.g., a medicament, infused down the catheter's lumen, the fluid flowing out of the side port(s) to treat the anatomical location. Alternative embodiments may include a translatable inner sheath that may cover some of the side port(s) and may also include an aperture that may align with at least one of the side port(s). The side ports may be opened and closed by means of an acuator such as a push/pull wire or an electrically response shape memory material. A selective filter may be used to cover the side ports, whereby only fluids of certain viscosities and/or molecular size may pass through the filter and side port.
(FR) L'invention concerne un cathéter avec une lumière et comprenant au moins un orifice latéral à travers le corps allongé du cathéter à des emplacements prédéterminés. L'au moins un orifice latéral peut être positionné à des emplacements anatomiques d'intérêt et un fluide, par exemple un médicament, est infusé en bas de la lumière du cathéter, le fluide s'écoulant hors de l'au moins un orifice latéral pour traiter l'emplacement anatomique. D'autres modes de réalisation peuvent comprendre une gaine interne pouvant être déplacée qui peut recouvrir certains orifices latéraux parmi l'au moins un orifice latéral et peut également comprendre une ouverture qui peut s'aligner avec au moins l'un de l'au moins un orifice latéral. Les orifices latéraux peuvent être ouverts et fermés au moyen d'un actionneur tel qu'un fil de poussée/traction ou un matériau à mémoire de forme à réponse électrique. Un filtre sélectif peut être utilisé pour couvrir les orifices latéraux, moyennant quoi seuls des fluides de certaines viscosités et/ou de taille moléculaire peuvent passer à travers le filtre et l'orifice latéral.
